- Monitor Functions:
Monitor commands can be included or excluded
from the build by using the #include files
- "config_cmd_all.h" and #undef'ing unwanted
- commands, or using "config_cmd_default.h"
+ <config_cmd_all.h> and #undef'ing unwanted
+ commands, or using <config_cmd_default.h>
and augmenting with additional #define's
for wanted commands.
If this variable is defined, an environment variable
named "ver" is created by U-Boot showing the U-Boot
version as printed by the "version" command.
- This variable is readonly.
+ Any change to this variable will be reverted at the
+ next reset.
- Real-Time Clock:
commands like bootm or iminfo. This option is
automatically enabled when you select CONFIG_CMD_DATE .
-- Partition Support:
- CONFIG_MAC_PARTITION and/or CONFIG_DOS_PARTITION
- and/or CONFIG_ISO_PARTITION and/or CONFIG_EFI_PARTITION
+- Partition Labels (disklabels) Supported:
+ Zero or more of the following:
+ CONFIG_MAC_PARTITION Apple's MacOS partition table.
+ CONFIG_DOS_PARTITION MS Dos partition table, traditional on the
+ Intel architecture, USB sticks, etc.
+ CONFIG_ISO_PARTITION ISO partition table, used on CDROM etc.
+ CONFIG_EFI_PARTITION GPT partition table, common when EFI is the
+ bootloader. Note 2TB partition limit; see
+ disk/part_efi.c
+ CONFIG_MTD_PARTITIONS Memory Technology Device partition table.
If IDE or SCSI support is enabled (CONFIG_CMD_IDE or
CONFIG_CMD_SCSI) you must configure support for at
- least one partition type as well.
+ least one non-MTD partition type as well.
- IDE Reset method:
CONFIG_IDE_RESET_ROUTINE - this is defined in several
Disable PCI-Express on systems where it is supported but not
required.
+- CONFIG_PCI_ENUM_ONLY
+ Only scan through and get the devices on the busses.
+ Don't do any setup work, presumably because someone or
+ something has already done it, and we don't need to do it
+ a second time. Useful for platforms that are pre-booted
+ by coreboot or similar.

- info->start = mpart.start_block;
- info->size = mpart.block_count;
- memcpy (info->type, mpart.type, sizeof(info->type));
- memcpy (info->name, mpart.name, sizeof(info->name));
+ info->start = mpart->start_block;
+ info->size = mpart->block_count;
+ memcpy (info->type, mpart->type, sizeof(info->type));
+ memcpy (info->name, mpart->name, sizeof(info->name));
return (0);
}
This this case CPU will be set to "normal_cpu" during the main u-boot
build and "spl_cpu" during the SPL build.
+
+
+Debugging
+---------
+
+When building SPL with DEBUG set you may also need to set CONFIG_PANIC_HANG
+as in most cases do_reset is not defined within SPL.
+
+
+Estimating stack usage
+----------------------
+
+With gcc 4.6 (and later) and the use of GNU cflow it is possible to estimate
+stack usage at various points in run sequence of SPL. The -fstack-usage option
+to gcc will produce '.su' files (such as arch/arm/cpu/armv7/syslib.su) that
+will give stack usage information and cflow can construct program flow.
+
+Must have gcc 4.6 or later, which supports -fstack-usage
+
+1) Build normally
+2) Perform the following shell command to generate a list of C files used in
+SPL:
+$ find spl -name '*.su' | sed -e 's:^spl/::' -e 's:[.]su$:.c:' > used-spl.list
+3) Execute cflow:
+$ cflow --main=board_init_r `cat used-spl.list` 2>&1 | $PAGER
+
+cflow will spit out a number of warnings as it does not parse
+the config files and picks functions based on #ifdef. Parsing the '.i'
+files instead introduces another set of headaches. These warnings are
+not usually important to understanding the flow, however.

+How to enable PMECC(Programmable Multibit ECC) for nand on Atmel SoCs
+-----------------------------------------------------------
+2012-08-22 Josh Wu <josh.wu@atmel.com>
+
+The Programmable Multibit ECC (PMECC) controller is a programmable binary
+BCH(Bose, Chaudhuri and Hocquenghem) encoder and decoder. This controller
+can be used to support both SLC and MLC NAND Flash devices. It supports to
+generate ECC to correct 2, 4, 8, 12 or 24 bits of error per sector (512 or
+1024 bytes) of data.
+
+Following Atmel AT91 products support PMECC.
+- AT91SAM9X25, X35, G25, G15, G35 (tested)
+- AT91SAM9N12 (not tested, Should work)
+
+As soon as your nand flash software ECC works, you can enable PMECC.
+
+To use PMECC in this driver, the user needs to set:
+ 1. the PMECC correction error bits capability: CONFIG_PMECC_CAP.
+ It can be 2, 4, 8, 12 or 24.
+ 2. The PMECC sector size: CONFIG_PMECC_SECTOR_SIZE.
+ It only can be 512 or 1024.
+ 3. The PMECC index lookup table's offsets in ROM code: CONFIG_PMECC_INDEX_TABLE_OFFSET.
+ In the chip datasheet section "Boot Stragegies", you can find
+ two Galois Field Table in the ROM code. One table is for 512-bytes
+ sector. Another is for 1024-byte sector. Each Galois Field includes
+ two sub-table: indext table & alpha table.
+ In the beginning of each Galois Field Table is the index table,
+ Alpha table is in the following.
+ So the index table's offset is same as the Galois Field Table.
+
+ Please set CONFIG_PMECC_INDEX_TABLE_OFFSET correctly according the
+ Galois Field Table's offset base on the sector size you used.
+
+Take AT91SAM9X5EK as an example, the board definition file likes:
+
+/* PMECC & PMERRLOC */
+#define CONFIG_ATMEL_NAND_HWECC 1
+#define CONFIG_ATMEL_NAND_HW_PMECC 1
+#define CONFIG_PMECC_CAP 2
+#define CONFIG_PMECC_SECTOR_SIZE 512
+#define CONFIG_PMECC_INDEX_TABLE_OFFSET 0x8000
+
+NOTE: If you use 1024 as the sector size, then need set 0x10000 as the
+ CONFIG_PMECC_INDEX_TABLE_OFFSET

+The U-Boot Driver Model Project
+===============================
+Block device subsystem analysis
+===============================
+
+Pavel Herrmann <morpheus.ibis@gmail.com>
+2012-03-08
+
+I) Overview
+-----------
+
+ U-Boot currently implements several distinct APIs for block devices - some
+ drivers use the SATA API, some drivers use the IDE API, sym53c8xx and
+ AHCI use the SCSI API, mg_disk has a separate API, and systemace also has a
+ separate API. There are also MMC and USB APIs used outside of drivers/block,
+ those will be detailed in their specific documents.
+
+ Block devices are described by block_dev_desc structure, that holds, among
+ other things, the read/write/erase callbacks. Block device structures are
+ stored in any way depending on the API, but can be accessed by
+
+ block_dev_desc_t * $api_get_dev(int dev)
+
+ function, as seen in disk/part.c.
+
+ 1) SATA interface
+ -----------------
+
+ The SATA interface drivers implement the following functions:
+
+ int init_sata(int dev)
+ int scan_sata(int dev)
+ ulong sata_read(int dev, ulong blknr, ulong blkcnt, void *buffer)
+ ulong sata_write(int dev, ulong blknr, ulong blkcnt, const void *buffer)
+
+ Block devices are kept in sata_dev_desc[], which is prefilled with values
+ common to all SATA devices in cmd_sata.c, and then modified in init_sata
+ function in the drivers. Callbacks of the block device use SATA API
+ directly. The sata_get_dev function is defined in cmd_sata.c.
+
+ 2) SCSI interface
+ -----------------
+
+ The SCSI interface drivers implement the following functions:
+
+ void scsi_print_error(ccb *pccb)
+ int scsi_exec(ccb *pccb)
+ void scsi_bus_reset(void)
+ void scsi_low_level_init(int busdevfunc)
+
+ The SCSI API works through the scsi_exec function, the actual operation
+ requested is found in the ccb structure.
+
+ Block devices are kept in scsi_dev_desc[], which lives only in cmd_scsi.c.
+ Callbacks of the block device use functions from cmd_scsi.c, which in turn
+ call scsi_exec of the controller. The scsi_get_dev function is also defined
+ in cmd_scsi.c.
+
+ 3) mg_disk interface
+ --------------------
+
+ The mg_disk interface drivers implement the following functions:
+
+ struct mg_drv_data* mg_get_drv_data (void)
+ uint mg_disk_init (void)
+ uint mg_disk_read (u32 addr, u8 *buff, u32 len)
+ uint mg_disk_write(u32 addr, u8 *buff, u32 len)
+ uint mg_disk_write_sects(void *buff, u32 sect_num, u32 sect_cnt)
+ uint mg_disk_read_sects(void *buff, u32 sect_num, u32 sect_cnt)
+
+ The mg_get_drv_data function is to be overridden per-board, but there are no
+ board in-tree that do this.
+
+ Only one driver for this API exists, and it only supports one block device.
+ Callbacks for this device are implemented in mg_disk.c and call the mg_disk
+ API. The mg_disk_get_dev function is defined in mg_disk.c and ignores the
+ device number, always returning the same device.
+
+ 4) systemace interface
+ ----------------------
+
+ The systemace interface does not define any driver API, and has no command
+ itself. The single defined function is systemace_get_devs() from
+ systemace.c, which returns a single static structure for the only supported
+ block device. Callbacks for this device are also implemented in systemace.c.
+
+ 5) IDE interface
+ ----------------
+
+ The IDE interface drivers implement the following functions, but only if
+ CONFIG_IDE_AHB is set:
+
+ uchar ide_read_register(int dev, unsigned int port);
+ void ide_write_register(int dev, unsigned int port, unsigned char val);
+ void ide_read_data(int dev, ulong *sect_buf, int words);
+ void ide_write_data(int dev, ulong *sect_buf, int words);
+
+ The first two functions are called from ide_inb()/ide_outb(), and will
+ default to direct memory access if CONFIG_IDE_AHB is not set, or
+ ide_inb()/ide_outb() functions will get overridden by the board altogether.
+
+ The second two functions are called from input_data()/output_data()
+ functions, and also default to direct memory access, but cannot be
+ overridden by the board.
+
+ One function shared by IDE drivers (but not defined in ide.h) is
+ int ide_preinit(void)
+ This function gets called from ide_init in cmd_ide.c if CONFIG_IDE_PREINIT
+ is defined, and will do the driver-specific initialization of the device.
+
+ Block devices are kept in ide_dev_desc[], which is filled in cmd_ide.c.
+ Callbacks of the block device are defined in cmd_ide.c, and use the
+ ide_inb()/ide_outb()/input_data()/output_data() functions mentioned above.
+ The ide_get_dev function is defined in cmd_ide.c.
+
+II) Approach
+------------
+
+ A new block controller core and an associated API will be created to mimic the
+ current SATA API, its drivers will have the following ops:
+
+ struct block_ctrl_ops {
+ int scan(instance *i);
+ int reset(instance *i, int port);
+ lbaint_t read(instance *i, int port, lbaint_t start, lbatin_t length,
+ void *buffer);
+ lbaint_t write(instance *i, int port, lbaint_t start, lbatin_t length,
+ void*buffer);
+ }
+
+ The current sata_init() function will be changed into the driver probe()
+ function. The read() and write() functions should never be called directly,
+ instead they should be called by block device driver for disks.
+
+ Other block APIs would either be transformed into this API, or be kept as
+ legacy for old drivers, or be dropped altogether.
+
+ Legacy driver APIs will each have its own driver core that will contain the
+ shared logic, which is currently located mostly in cmd_* files. Callbacks for
+ block device drivers will then probably be implemented as a part of the core
+ logic, and will use the driver ops (which will copy current state of
+ respective APIs) to do the work.
+
+ All drivers will be cleaned up, most ifdefs should be converted into
+ platform_data, to enable support for multiple devices with different settings.
+
+ A new block device core will also be created, and will keep track of all
+ block devices on all interfaces.
+
+ Current block_dev_desc structure will be changed to fit the driver model, all
+ identification and configuration will be placed in private data, and
+ a single accessor and modifier will be defined, to accommodate the need for
+ different sets of options for different interfaces, while keeping the
+ structure small. The new block device drivers will have the following ops
+ structure (lbaint_t is either 32bit or 64bit unsigned, depending on
+ CONFIG_LBA48):
+
+ struct blockdev_ops {
+ lbaint_t (*block_read)(struct instance *i, lbaint_t start, lbaint_t blkcnt,
+ void *buffer);
+ lbaint_t (*block_write)(struct instance *i, lbaint_t start, lbaint_t blkcnt,
+ void *buffer);
+ lbaint_t (*block_erase)(struct instance *i, lbaint_t start, lbaint_t blkcnt
+ );
+ int (*get_option)(struct instance *i, enum blockdev_option_code op,
+ struct option *res);
+ int (*set_option)(struct instance *i, enum blockdev_option_code op,
+ struct option *val);
+ }
+
+ struct option {
+ uint32_t flags
+ union data {
+ uint64_t data_u;
+ char* data_s;
+ void* data_p;
+ }
+ }
+
+ enum blockdev_option_code {
+ BLKD_OPT_IFTYPE=0,
+ BLKD_OPT_TYPE,
+ BLKD_OPT_BLOCKSIZE,
+ BLKD_OPT_BLOCKCOUNT,
+ BLKD_OPT_REMOVABLE,
+ BLKD_OPT_LBA48,
+ BLKD_OPT_VENDOR,
+ BLKD_OPT_PRODICT,
+ BLKD_OPT_REVISION,
+ BLKD_OPT_SCSILUN,
+ BLKD_OPT_SCSITARGET,
+ BLKD_OPT_OFFSET
+ }
+
+ Flags in option above will contain the type of returned data (which should be
+ checked against what is expected, even though the option requested should
+ specify it), and a flag to indicate whether the returned pointer needs to be
+ free()'d.
+
+ The block device core will contain the logic now located in disk/part.c and
+ related files, and will be used to forward requests to block devices. The API
+ for the block device core will copy the ops of a block device (with a string
+ identifier instead of instance pointer). This means that partitions will also
+ be handled by the block device core, and exported as block devices, making
+ them transparent to the rest of the code.
+
+ Sadly, this will change how file systems can access the devices, and thus will
+ affect a lot of places. However, these changes should be localized and easy to
+ implement.
+
+ AHCI driver will be rewritten to fit the new unified block controller API,
+ making SCSI API easy to merge with sym53c8xx, or remove it once the device
+ driver has died.
+
+ Optionally, IDE core may be changed into one driver with unified block
+ controller API, as most of it is already in one place and device drivers are
+ just sets of hooks. Additionally, mg_disk driver is unused and may be removed
+ in near future.
+
+
+
+III) Analysis of in-tree drivers
+--------------------------------
+
+ 1) ahci.c
+ ---------
+ SCSI API, will be rewritten for a different API.
+
+ 2) ata_piix.c
+ -------------
+ SATA API, easy to port.
+
+ 3) fsl_sata.c
+ -------------
+ SATA API, few CONFIG macros, easy to port.
+
+ 4) ftide020.c
+ -------------
+ IDE API, defines CONFIG_IDE_AHB and ide_preinit hook functions.
+
+ 5) mg_disk.c
+ ------------
+ Single driver with mg_disk API, not much to change, easy to port.
+
+ 6) mvsata_ide.c
+ ---------------
+ IDE API, only defines ide_preinit hook function.
+
+ 7) mxc_ata.c
+ ------------

+
+ 11) sata_sil.c
+ --------------
+ SATA API, easy to port.
+
+ 12) sil680.c
+ ------------
+ IDE API, only defines ide_preinit hook function.
+
+ 13) sym53c8xx.c
+ ---------------
+ SCSI API, may be merged with code from cmd_scsi.
+
+ 14) systemace.c
+ ---------------
+ Single driver with systemace API, not much to change, easy to port.

+The U-Boot Driver Model Project
+===============================
+Driver cores API document
+=========================
+
+Pavel Herrmann <morpheus.ibis@gmail.com>
+
+1) Overview
+-----------
+ Driver cores will be used as a wrapper for devices of the same type, and as
+ an abstraction for device driver APIs. For each driver API (which roughly
+ correspond to device types), there will be one driver core. Each driver core
+ will implement three APIs - a driver API (which will be the same as API of
+ drivers the core wraps around), a core API (which will be implemented by all
+ cores) and a command API (core-specific API which will be exposed to
+ commands).
+
+ A) Command API
+ The command API will provide access to shared functionality for a specific
+ device, which is currently located mostly in commands. Commands will be
+ rewritten to be more lightweight by using this API. As this API will be
+ different for each core, it is out of scope of this document.
+
+ B) Driver API
+ The driver API will act as a wrapper around actual device drivers,
+ providing a single entrypoint for device access. All functions in this API
+ have an instance* argument (probably called "this" or "i"), which will be
+ examined by the core, and a correct function for the specified driver will
+ get called.
+
+ If the core gets called with a group instance pointer (as discussed in
+ design), it will automatically select the instance that is associated
+ with this core, and use it as target of the call. if the group contains
+ multiple instances of a single type, the caller must explicitly use an
+ accessor to select the correct instance.
+
+ This accessor will look like:
+ struct instance *get_instance_from_group(struct instance *group, int i)
+
+ When called with a non-group instance, it will simply return the instance.
+
+ C) Core API
+ The core API will be implemented by all cores, and will provide
+ functionality for getting driver instances from non-driver code. This API
+ will consist of following functions:
+
+ int get_count(struct instance *core);
+ struct instance* get_instance(struct instance *core, int index);
+ int init(struct instance *core);
+ int bind(struct instance *core, struct instance *dev, void *ops,
+ void *hint);
+ int unbind(struct instance *core, instance *dev);
+ int replace(struct instance *core, struct_instance *new_dev,
+ struct instance *old_dev);
+ int destroy(struct instance *core);
+ int reloc(struct instance *new_core, struct instance *old_core);
+
+ The 'hint' parameter of bind() serves for additional data a driver can
+ pass to the core, to help it create the correct internal state for this
+ instance. the replace() function will get called during instance
+ relocation, and will replace the old instance with the new one, keeping
+ the internal state untouched.
+
+
+2) Lifetime of a driver core
+----------------------------
+ Driver cores will be initialized at runtime, to limit memory footprint in
+ early-init stage, when we have to fit into ~1KB of memory. All active cores
+ will be stored in a tree structure (referenced as "Core tree") in global data,
+ which provides good tradeoff between size and access time.
+ Every core will have a number constant associated with it, which will be used
+ to find the instance in Core tree, and to refer to the core in all calls
+ working with the Core tree.
+ The Core Tree should be implemented using B-tree (or a similar structure)
+ to guarantee acceptable time overhead in all cases.
+
+ Code for working with the core (i2c in this example) follows:
+
+ core_init(CORE_I2C);
+ This will check whether we already have a i2c core, and if not it creates
+ a new instance and adds it into the Core tree. This will not be exported,
+ all code should depend on get_core_instance to init the core when
+ necessary.
+
+ get_core_instance(CORE_I2C);
+ This is an accessor into the Core tree, which will return the instance
+ of i2c core, creating it if necessary
+
+ core_bind(CORE_I2C, instance, driver_ops);
+ This will get called in bind() function of a driver, and will add the
+ instance into cores internal list of devices. If the core is not found, it
+ will get created.
+
+ driver_activate(instance *inst);
+ This call will recursively activate all devices necessary for using the
+ specified device. the code could be simplified as:
+ {
+ if (is_activated(inst))
+ return;
+ driver_activate(inst->bus);
+ get_driver(inst)->probe(inst);
+ }
+
+ The case with multiple parents will need to be handled here as well.
+ get_driver is an accessor to available drivers, which will get struct
+ driver based on a name in the instance.
+
+ i2c_write(instance *inst, ...);
+ An actual call to some method of the driver. This code will look like:
+ {
+ driver_activate(inst);
+ struct instance *core = get_core_instance(CORE_I2C);
+ device_ops = get_ops(inst);
+ device_ops->write(...);
+ }
+
+ get_ops will not be an exported function, it will be internal and specific
+ to the core, as it needs to know how are the ops stored, and what type
+ they are.
+
+ Please note that above examples represent the algorithm, not the actual code,
+ as they are missing checks for validity of return values.
+
+ core_init() function will get called the first time the core is requested,
+ either by core_link() or core_get_instance(). This way, the cores will get
+ created only when they are necessary, which will reduce our memory footprint.

+The U-Boot Driver Model Project
+===============================
+Design document
+===============
+Marek Vasut <marek.vasut@gmail.com>
+Pavel Herrmann <morpheus.ibis@gmail.com>
+2012-05-17
+
+I) The modular concept
+----------------------
+
+The driver core design is done with modularity in mind. The long-term plan is to
+extend this modularity to allow loading not only drivers, but various other
+objects into U-Boot at runtime -- like commands, support for other boards etc.
+
+II) Driver core initialization stages
+-------------------------------------
+
+The drivers have to be initialized in two stages, since the U-Boot bootloader
+runs in two stages itself. The first stage is the one which is executed before
+the bootloader itself is relocated. The second stage then happens after
+relocation.
+
+ 1) First stage
+ --------------
+
+ The first stage runs after the bootloader did very basic hardware init. This
+ means the stack pointer was configured, caches disabled and that's about it.
+ The problem with this part is the memory management isn't running at all. To
+ make things even worse, at this point, the RAM is still likely uninitialized
+ and therefore unavailable.
+
+ 2) Second stage
+ ---------------
+
+ At this stage, the bootloader has initialized RAM and is running from it's
+ final location. Dynamic memory allocations are working at this point. Most of
+ the driver initialization is executed here.
+
+III) The drivers
+----------------
+
+ 1) The structure of a driver
+ ----------------------------
+
+ The driver will contain a structure located in a separate section, which
+ will allow linker to create a list of compiled-in drivers at compile time.
+ Let's call this list "driver_list".
+
+ struct driver __attribute__((section(driver_list))) {
+ /* The name of the driver */
+ char name[STATIC_CONFIG_DRIVER_NAME_LENGTH];
+
+ /*
+ * This function should connect this driver with cores it depends on and
+ * with other drivers, likely bus drivers
+ */
+ int (*bind)(struct instance *i);
+
+ /* This function actually initializes the hardware. */
+ int (*probe)(struct instance *i);
+
+ /*
+ * The function of the driver called when U-Boot finished relocation.
+ * This is particularly important to eg. move pointers to DMA buffers
+ * and such from the location before relocation to their final location.
+ */
+ int (*reloc)(struct instance *i);
+
+ /*
+ * This is called when the driver is shuting down, to deinitialize the
+ * hardware.
+ */
+ int (*remove)(struct instance *i);
+
+ /* This is called to remove the driver from the driver tree */
+ int (*unbind)(struct instance *i);
+
+ /* This is a list of cores this driver depends on */
+ struct driver *cores[];
+ };
+
+ The cores[] array in here is very important. It allows u-boot to figure out,
+ in compile-time, which possible cores can be activated at runtime. Therefore
+ if there are cores that won't be ever activated, GCC LTO might remove them
+ from the final binary. Actually, this information might be used to drive build
+ of the cores.
+
+ FIXME: Should *cores[] be really struct driver, pointing to drivers that
+ represent the cores? Shouldn't it be core instance pointer?
+
+ 2) Instantiation of a driver
+ ----------------------------
+
+ The driver is instantiated by calling:
+
+ driver_bind(struct instance *bus, const struct driver_info *di)
+
+ The "struct instance *bus" is a pointer to a bus with which this driver should
+ be registered with. The "root" bus pointer is supplied to the board init
+ functions.
+
+ FIXME: We need some functions that will return list of busses of certain type
+ registered with the system so the user can find proper instance even if
+ he has no bus pointer (this will come handy if the user isn't
+ registering the driver from board init function, but somewhere else).
+
+ The "const struct driver_info *di" pointer points to a structure defining the
+ driver to be registered. The structure is defined as follows:
+
+ struct driver_info {
+ char name[STATIC_CONFIG_DRIVER_NAME_LENGTH];
+ void *platform_data;
+ }
+
+ The instantiation of a driver by calling driver_bind() creates an instance
+ of the driver by allocating "struct driver_instance". Note that only struct
+ instance is passed to the driver. The wrapping struct driver_instance is there
+ for purposes of the driver core:
+
+ struct driver_instance {
+ uint32_t flags;
+ struct instance i;
+ };
+
+ struct instance {
+ /* Pointer to a driver information passed by driver_register() */
+ const struct driver_info *info;
+ /* Pointer to a bus this driver is bound with */
+ struct instance *bus;
+ /* Pointer to this driver's own private data */
+ void *private_data;
+ /* Pointer to the first block of successor nodes (optional) */
+ struct successor_block *succ;
+ }
+
+ The instantiation of a driver does not mean the hardware is initialized. The
+ driver_bind() call only creates the instance of the driver, fills in the "bus"
+ pointer and calls the drivers' .bind() function. The .bind() function of the
+ driver should hook the driver with the remaining cores and/or drivers it
+ depends on.
+
+ It's important to note here, that in case the driver instance has multiple
+ parents, such parent can be connected with this instance by calling:
+
+ driver_link(struct instance *parent, struct instance *dev);
+
+ This will connect the other parent driver with the newly instantiated driver.
+ Note that this must be called after driver_bind() and before driver_acticate()
+ (driver_activate() will be explained below). To allow struct instance to have
+ multiple parent pointer, the struct instance *bus will utilize it's last bit
+ to indicate if this is a pointer to struct instance or to an array if
+ instances, struct successor block. The approach is similar as the approach to
+ *succ in struct instance, described in the following paragraph.
+
+ The last pointer of the struct instance, the pointer to successor nodes, is
+ used only in case of a bus driver. Otherwise the pointer contains NULL value.
+ The last bit of this field indicates if this is a bus having a single child
+ node (so the last bit is 0) or if this bus has multiple child nodes (the last
+ bit is 1). In the former case, the driver core should clear the last bit and
+ this pointer points directly to the child node. In the later case of a bus
+ driver, the pointer points to an instance of structure:
+
+ struct successor_block {
+ /* Array of pointers to instances of devices attached to this bus */
+ struct instance *dev[BLOCKING_FACTOR];
+ /* Pointer to next block of successors */
+ struct successor_block *next;
+ }
+
+ Some of the *dev[] array members might be NULL in case there are no more
+ devices attached. The *next is NULL in case the list of attached devices
+ doesn't continue anymore. The BLOCKING_FACTOR is used to allocate multiple
+ slots for successor devices at once to avoid fragmentation of memory.
+
+ 3) The bind() function of a driver
+ ----------------------------------
+
+ The bind function of a driver connects the driver with various cores the
+ driver provides functions for. The driver model related part will look like
+ the following example for a bus driver:
+
+ int driver_bind(struct instance *in)
+ {
+ ...
+ core_bind(&core_i2c_static_instance, in, i2c_bus_funcs);
+ ...
+ }
+
+ FIXME: What if we need to run-time determine, depending on some hardware
+ register, what kind of i2c_bus_funcs to pass?
+
+ This makes the i2c core aware of a new bus. The i2c_bus_funcs is a constant
+ structure of functions any i2c bus driver must provide to work. This will
+ allow the i2c command operate with the bus. The core_i2c_static_instance is
+ the pointer to the instance of a core this driver provides function to.
+
+ FIXME: Maybe replace "core-i2c" with CORE_I2C global pointer to an instance of
+ the core?
+
+ 4) The instantiation of a core driver
+ -------------------------------------
+
+ The core driver is special in the way that it's single-instance driver. It is
+ always present in the system, though it might not be activated. The fact that
+ it's single instance allows it to be instantiated at compile time.
+
+ Therefore, all possible structures of this driver can be in read-only memory,
+ especially struct driver and struct driver_instance. But the successor list,
+ which needs special treatment.
+
+ To solve the problem with a successor list and the core driver flags, a new
+ entry in struct gd (global data) will be introduced. This entry will point to
+ runtime allocated array of struct driver_instance. It will be possible to
+ allocate the exact amount of struct driver_instance necessary, as the number
+ of cores that might be activated will be known at compile time. The cores will
+ then behave like any usual driver.
+
+ Pointers to the struct instance of cores can be computed at compile time,
+ therefore allowing the resulting u-boot binary to save some overhead.
+
+ 5) The probe() function of a driver
+ -----------------------------------
+
+ The probe function of a driver allocates necessary resources and does required
+ initialization of the hardware itself. This is usually called only when the
+ driver is needed, as a part of the defered probe mechanism.
+
+ The driver core should implement a function called
+
+ int driver_activate(struct instance *in);
+
+ which should call the .probe() function of the driver and then configure the
+ state of the driver instance to "ACTIVATED". This state of a driver instance
+ should be stored in a wrap-around structure for the structure instance, the
+ struct driver_instance.
+
+ 6) The command side interface to a driver
+ -----------------------------------------
+
+ The U-Boot command shall communicate only with the specific driver core. The
+ driver core in turn exports necessary API towards the command.
+
+ 7) Demonstration imaginary board
+ --------------------------------
+
+ Consider the following computer:

+ +-- System power management logic
+ |
+ +-- CPU clock controlling logc

+ +-- NAND controller

+I/O system analysis
+===================
+Marek Vasut <marek.vasut@gmail.com>
+2012-02-21
+
+I) Overview
+-----------
+
+The current FPGA implementation is handled by command "fpga". This command in
+turn calls the following functions:
+
+fpga_info()
+fpga_load()
+fpga_dump()
+
+These functions are implemented by what appears to be FPGA multiplexer, located
+in drivers/fpga/fpga.c . This code determines which device to operate with
+depending on the device ID.
+
+The fpga_info() function is multiplexer of the functions providing information
+about the particular FPGA device. These functions are implemented in the drivers
+for the particular FPGA device:
+
+xilinx_info()
+altera_info()
+lattice_info()
+
+Similar approach is used for fpga_load(), which multiplexes "xilinx_load()",
+"altera_load()" and "lattice_load()" and is used to load firmware into the FPGA
+device.
+
+The fpga_dump() function, which prints the contents of the FPGA device, is no
+different either, by multiplexing "xilinx_dump()", "altera_dump()" and
+"lattice_dump()" functions.
+
+Finally, each new FPGA device is registered by calling "fpga_add()" function.
+This function takes two arguments, the second one being particularly important,
+because it's basically what will become platform_data. Currently, it's data that
+are passed to the driver from the board/platform code.
+
+II) Approach
+------------
+
+The path to conversion of the FPGA subsystem will be very straightforward, since
+the FPGA subsystem is already quite dynamic. Multiple things will need to be
+modified though.
+
+First is the registration of the new FPGA device towards the FPGA core. This
+will be achieved by calling:
+
+ fpga_device_register(struct instance *i, const struct fpga_ops *ops);
+
+The particularly interesting part is the struct fpga_ops, which contains
+operations supported by the FPGA device. These are basically the already used
+calls in the current implementation:
+
+struct fpga_ops {
+ int info(struct instance *i);
+ int load(struct instance *i, const char *buf, size_t size);
+ int dump(struct instance *i, const char *buf, size_t size);
+}
+
+The other piece that'll have to be modified is how the devices are tracked.
+It'll be necessary to introduce a linked list of devices within the FPGA core
+instead of tracking them by ID number.
+
+Next, the "Xilinx_desc", "Lattice_desc" and "Altera_desc" structures will have
+to be moved to driver's private_data. Finally, structures passed from the board
+and/or platform files, like "Xilinx_Virtex2_Slave_SelectMap_fns" would be passed
+via platform_data to the driver.
+
+III) Analysis of in-tree drivers
+--------------------------------
+
+ 1) Altera driver
+ ----------------
+ The driver is realized using the following files:
+
+ drivers/fpga/altera.c
+ drivers/fpga/ACEX1K.c
+ drivers/fpga/cyclon2.c
+ drivers/fpga/stratixII.c
+
+ All of the sub-drivers implement basically the same info-load-dump interface
+ and there's no expected problem during the conversion. The driver itself will
+ be realised by altera.c and all the sub-drivers will be linked in. The
+ distinction will be done by passing different platform data.
+
+ 2) Lattice driver
+ -----------------
+ The driver is realized using the following files:
+
+ drivers/fpga/lattice.c
+ drivers/fpga/ivm_core.c
+
+ This driver also implements the standard interface, but to realise the
+ operations with the FPGA device, uses functions from "ivm_core.c" file. This
+ file implements the main communications logic and has to be linked in together
+ with "lattice.c". No problem converting is expected here.
+
+ 3) Xilinx driver
+ ----------------
+ The driver is realized using the following files:
+
+ drivers/fpga/xilinx.c
+ drivers/fpga/spartan2.c
+ drivers/fpga/spartan3.c
+ drivers/fpga/virtex2.c
+
+ This set of sub-drivers is special by defining a big set of macros in
+ "include/spartan3.h" and similar files. These macros would need to be either
+ rewritten or replaced. Otherwise, there are no problems expected during the
+ conversion process.

+===============================
+GPIO analysis
+=============
+Viktor Krivak <viktor.krivak@gmail.com>
+2012-02-24
+
+I) Overview
+-----------
+
+ At this moment U-Boot provides standard API that consists of 7 functions.
+
+ int gpio_request(unsigned gpio, const char *label)
+ int gpio_free(unsigned gpio)
+ int gpio_direction_input(unsigned gpio)
+ int gpio_direction_output(unsigned gpio, int value)
+ int gpio_get_value(unsigned gpio)
+ void gpio_set_value(unsigned gpio, int value)
+
+ Methods "gpio_request()" and "gpio_free()" are used for claiming and releasing
+ GPIOs. First one should check if the desired pin exists and if the pin wasn't
+ requested already elsewhere. The method also has a label argument that can be
+ used for debug purposes. The label argument should be copied into the internal
+ memory, but only if the DEBUG macro is set. The "gpio_free()" is the exact
+ opposite. It releases the particular pin. Other methods are used for setting
+ input or output direction and obtaining or setting values of the pins.
+
+II) Approach
+------------
+
+ 1) Request and free GPIO
+ ------------------------
+
+ The "gpio_request()" implementation is basically the same for all boards.
+ The function checks if the particular GPIO is correct and checks if the
+ GPIO pin is still free. If the conditions are met, the method marks the
+ GPIO claimed in it's internal structure. If macro DEBUG is defined, the
+ function also copies the label argument to the structure. If the pin is
+ already locked, the function returns -1 and if DEBUG is defined, certain
+ debug output is generated, including the contents of the label argument.
+ The "gpio_free()" function releases the lock and eventually deallocates
+ data used by the copied label argument.
+
+ 2) Internal data
+ ----------------
+
+ Internal data are driver specific. They have to contain some mechanism to
+ realise the locking though. This can be done for example using a bit field.
+
+ 3) Operations provided by the driver
+ ------------------------------------
+
+ The driver operations basically meet API that is already defined and used.
+ Except for "gpio_request()" and "gpio_free()", all methods can be converted in
+ a simple manner. The driver provides the following structure:
+
+ struct gpio_driver_ops {
+ int (*gpio_request)(struct instance *i, unsigned gpio,
+ const char *label);
+ int (*gpio_free)(struct instance *i, unsigned gpio);
+ int (*gpio_direction_input)(struct instance *i, unsigned gpio);
+ int (*gpio_direction_output)(struct instance *i, unsigned gpio,
+ int value);
+ int (*gpio_get_value)(struct instance *i, unsigned gpio);
+ void (*gpio_set_value)(struct instance *i, unsigned gpio, int value);
+ }
+
+III) Analysis of in-tree drivers
+--------------------------------
+
+ 1) altera_pio.c
+ ---------------
+ Meets standard API. Implements gpio_request() properly. Simple conversion
+ possible.
+
+ 2) at91_gpio.c
+ --------------
+ Don't meet standard API. Need some other methods to implement.
+
+ 3) da8xx_gpio.c
+ ---------------
+ Meets standard API. Implements gpio_request() properly. Simple conversion
+ possible.
+
+ 4) kw_gpio.c
+ ------------
+ Doesn't meet standard API. Needs some other methods to implement and move some
+ methods to another file.
+
+ 5) mpc83xx_gpio.c
+ -----------------
+ Meets standard API. Doesn't implement gpio_request() properly (only checks
+ if the pin is valid). Simple conversion possible.
+
+ 6) mvgpio.c
+ -----------
+ Meets standard API. Doesn't implement gpio_request() properly (only checks
+ if the pin is valid). Simple conversion possible.
+
+ 7) mvgpio.h
+ -----------
+ Wrong placement. Will be moved to another location.
+
+ 8) mvmfp.c
+ ----------
+ Wrong placement. Will be moved to another location.

+===============================
+Hwmon device subsystem analysis
+===============================
+
+Tomas Hlavacek <tmshlvck@gmail.com>
+2012-03-02
+
+I) Overview
+-----------
+
+U-Boot currently implements one API for HW monitoring devices. The
+interface is defined in include/dtt.h and comprises of functions:
+
+ void dtt_init(void);
+ int dtt_init_one(int);
+ int dtt_read(int sensor, int reg);
+ int dtt_write(int sensor, int reg, int val);
+ int dtt_get_temp(int sensor);
+
+The functions are implemented by a proper device driver in drivers/hwmon
+directory and the driver to be compiled in is selected in a Makefile.
+Drivers are mutually exclusive.
+
+Drivers depends on I2O code and naturally on board specific data. There are
+few ad-hoc constants put in dtt.h file and driver headers and code. This
+has to be consolidated into board specific data or driver headers if those
+constants makes sense globally.
+
+
+II) Approach
+------------
+
+ 1) New API
+ ----------
+ In the UDM each hwmon driver would register itself by a function
+
+ int hwmon_device_register(struct instance *i,
+ struct hwmon_device_ops *o);
+
+ The structure being defined as follows:
+
+ struct hwmon_device_ops {
+ int (*read)(struct instance *i, int sensor, int reg);
+ int (*write)(struct instance *i, int sensor, int reg,
+ int val);
+ int (*get_temp)(struct instance *i, int sensor);
+ };
+
+
+ 2) Conversion thougths
+ ----------------------
+ U-Boot hwmon drivers exports virtually the same functions (with exceptions)
+ and we are considering low number of drivers and code anyway. The interface
+ is already similar and unified by the interface defined in dtt.h.
+ Current initialization functions dtt_init() and dtt_init_one() will be
+ converted into probe() and hwmon_device_register(), so the funcionality will
+ be kept in more proper places. Besides implementing core registration and
+ initialization we need to do code cleanup, especially separate
+ driver-specific and HW specific constants.
+
+ 3) Special consideration due to early initialization
+ ----------------------------------------------------
+ The dtt_init() function call is used during early initialization in
+ board/gdsys/405ex/io64.c for starting up fans. The dtt code is perfectly
+ usable in the early stage because it uses only local variables and no heap
+ memory is required at this level. However the underlying code of I2C has to
+ keep the same properties with regard to possibility of running in early
+ initialization stage.
+
+III) Analysis of in-tree drivers
+--------------------------------
+
+ 1) drivers/hwmon/lm81.c
+ -----------------------
+ The driver is standard dtt. Simple conversion is possible.
+
+
+ 2) drivers/hwmon/ds1722.c
+ -------------------------
+ The driver is not standard dtt, but interface is similar to dtt.
+ The interface has to be changed in order to comply to above mentioned
+ specification.
+
+
+ 3) drivers/hwmon/ds1775.c
+ -------------------------
+ The driver is standard dtt. Simple conversion is possible.
+
+
+ 4) drivers/hwmon/lm73.c
+ -----------------------
+ The driver is standard dtt. Simple conversion is possible.
+
+
+ 5) drivers/hwmon/lm63.c
+ -----------------------
+ The driver is standard dtt. Simple conversion is possible.
+
+
+ 6) drivers/hwmon/adt7460.c
+ --------------------------
+ The driver is standard dtt. Simple conversion is possible.
+
+
+ 7) drivers/hwmon/lm75.c
+ -----------------------
+ The driver is standard dtt. Simple conversion is possible.
+
+
+ 8) drivers/hwmon/ds1621.c
+ -------------------------
+ The driver is standard dtt. Simple conversion is possible.
+
+
+ 9) drivers/hwmon/adm1021.c
+ --------------------------
+ The driver is standard dtt. Simple conversion is possible.

+Keyboard input analysis
+=======================
+Marek Vasut <marek.vasut@gmail.com>
+2012-02-20
+
+I) Overview
+-----------
+
+The keyboard drivers are most often registered with STDIO subsystem. There are
+components of the keyboard drivers though, which operate in severe ad-hoc
+manner, often being related to interrupt-driven keypress reception. This
+components will require the most sanitization of all parts of keyboard input
+subsystem.
+
+Otherwise, the keyboard is no different from other standard input but with the
+necessity to decode scancodes. These are decoded using tables provided by
+keyboard drivers. These tables are often driver specific.
+
+II) Approach
+------------
+
+The most problematic part is the interrupt driven keypress reception. For this,
+the buffers that are currently shared throughout the whole U-Boot would need to
+be converted into driver's private data.
+
+III) Analysis of in-tree drivers
+--------------------------------
+
+ 1) board/mpl/common/kbd.c
+ -------------------------
+ This driver is a classic STDIO driver, no problem with conversion is expected.
+ Only necessary change will be to move this driver to a proper location.
+
+ 2) board/rbc823/kbd.c
+ ---------------------
+ This driver is a classic STDIO driver, no problem with conversion is expected.
+ Only necessary change will be to move this driver to a proper location.
+
+ 3) drivers/input/keyboard.c
+ ---------------------------
+ This driver is special in many ways. Firstly because this is a universal stub
+ driver for converting scancodes from i8042 and the likes. Secondly because the
+ buffer is filled by various other ad-hoc implementations of keyboard input by
+ using this buffer as an extern. This will need to be fixed by allowing drivers
+ to pass certain routines to this driver via platform data.

+MMC system analysis
+===================
+Marek Vasut <marek.vasut@gmail.com>
+2012-02-25
+
+I) Overview
+-----------
+
+The MMC subsystem is already quite dynamic in it's nature. It's only necessary
+to flip the subsystem to properly defined API.
+
+The probing process of MMC drivers start by calling "mmc_initialize()",
+implemented by MMC framework, from the architecture initialization file. The
+"mmc_initialize()" function in turn calls "board_mmc_init()" function and if
+this doesn't succeed, "cpu_mmc_init()" function is called. It is important to
+note that both of the "*_mmc_init()" functions have weak aliases to functions
+which automatically fail.
+
+Both of the "*_mmc_init()" functions though serve only one purpose. To call
+driver specific probe function, which in turn actually registers the driver with
+MMC subsystem. Each of the driver specific probe functions is currently done in
+very ad-hoc manner.
+
+The registration with the MMC subsystem is done by calling "mmc_register()",
+whose argument is a runtime configured structure of information about the MMC
+driver. Currently, the information structure is intermixed with driver's internal
+data. The description of the structure follows:
+
+struct mmc {
+ /*
+ * API: Allows this driver to be a member of the linked list of all MMC drivers
+ * registered with MMC subsystem
+ */
+ struct list_head link;
+
+ /* DRIVER: Name of the registered driver */
+ char name[32];
+
+ /* DRIVER: Driver's private data */
+ void *priv;
+
+ /* DRIVER: Voltages the host bus can provide */
+ uint voltages;
+
+ /* API: Version of the card */
+ uint version;
+
+ /* API: Test if the driver was already initialized */
+ uint has_init;
+
+ /* DRIVER: Minimum frequency the host bus can provide */
+ uint f_min;
+
+ /* DRIVER: Maximum frequency the host bus can provide */
+ uint f_max;
+
+ /* API: Is the card SDHC */
+ int high_capacity;
+
+ /* API: Actual width of the bus used by the current card */
+ uint bus_width;
+
+ /*
+ * DRIVER: Clock frequency to be configured on the host bus, this is read-only
+ * for the driver.
+ */
+ uint clock;
+
+ /* API: Capabilities of the card */
+ uint card_caps;
+
+ /* DRIVER: MMC bus capabilities */
+ uint host_caps;
+
+ /* API: Configuration and ID data retrieved from the card */
+ uint ocr;
+ uint scr[2];
+ uint csd[4];
+ uint cid[4];
+ ushort rca;
+
+ /* API: Partition configuration */
+ char part_config;
+
+ /* API: Number of partitions */
+ char part_num;
+
+ /* API: Transmission speed */
+ uint tran_speed;
+
+ /* API: Read block length */
+ uint read_bl_len;
+
+ /* API: Write block length */
+ uint write_bl_len;
+
+ /* API: Erase group size */
+ uint erase_grp_size;
+
+ /* API: Capacity of the card */
+ u64 capacity;
+
+ /* API: Descriptor of this block device */
+ block_dev_desc_t block_dev;
+
+ /* DRIVER: Function used to submit command to the card */
+ int (*send_cmd)(struct mmc *mmc,
+ struct mmc_cmd *cmd, struct mmc_data *data);
+
+ /* DRIVER: Function used to configure the host */
+ void (*set_ios)(struct mmc *mmc);
+
+ /* DRIVER: Function used to initialize the host */
+ int (*init)(struct mmc *mmc);
+
+ /* DRIVER: Function used to report the status of Card Detect pin */
+ int (*getcd)(struct mmc *mmc);
+
+ /*
+ * DRIVER: Maximum amount of blocks sent during multiblock xfer,
+ * set to 0 to autodetect.
+ */
+ uint b_max;
+};
+
+The API above is the new API used by most of the drivers. There're still drivers
+in the tree that use old, legacy API though.
+
+2) Approach
+-----------
+
+To convert the MMC subsystem to a proper driver model, the "struct mmc"
+structure will have to be properly split in the first place. The result will
+consist of multiple parts, first will be the structure defining operations
+provided by the MMC driver:
+
+struct mmc_driver_ops {
+ /* Function used to submit command to the card */
+ int (*send_cmd)(struct mmc *mmc,
+ struct mmc_cmd *cmd, struct mmc_data *data);
+ /* DRIVER: Function used to configure the host */
+ void (*set_ios)(struct mmc *mmc);
+ /* Function used to initialize the host */
+ int (*init)(struct mmc *mmc);
+ /* Function used to report the status of Card Detect pin */
+ int (*getcd)(struct mmc *mmc);
+}
+
+The second part will define the parameters of the MMC driver:
+
+struct mmc_driver_params {
+ /* Voltages the host bus can provide */
+ uint32_t voltages;
+ /* Minimum frequency the host bus can provide */
+ uint32_t f_min;
+ /* Maximum frequency the host bus can provide */
+ uint32_t f_max;
+ /* MMC bus capabilities */
+ uint32_t host_caps;
+ /*
+ * Maximum amount of blocks sent during multiblock xfer,
+ * set to 0 to autodetect.
+ */
+ uint32_t b_max;
+}
+
+And finally, the internal per-card data of the MMC subsystem core:
+
+struct mmc_card_props {
+ /* Version of the card */
+ uint32_t version;
+ /* Test if the driver was already initializes */
+ bool has_init;
+ /* Is the card SDHC */
+ bool high_capacity;
+ /* Actual width of the bus used by the current card */
+ uint8_t bus_width;
+ /* Capabilities of the card */
+ uint32_t card_caps;
+ /* Configuration and ID data retrieved from the card */
+ uint32_t ocr;
+ uint32_t scr[2];
+ uint32_t csd[4];
+ uint32_t cid[4];
+ uint16_t rca;
+ /* Partition configuration */
+ uint8_t part_config;
+ /* Number of partitions */
+ uint8_t part_num;
+ /* Transmission speed */
+ uint32_t tran_speed;
+ /* Read block length */
+ uint32_t read_bl_len;
+ /* Write block length */
+ uint32_t write_bl_len;
+ /* Erase group size */
+ uint32_t erase_grp_size;
+ /* Capacity of the card */
+ uint64_t capacity;
+ /* Descriptor of this block device */
+ block_dev_desc_t block_dev;
+}
+
+The probe() function will then register the MMC driver by calling:
+
+ mmc_device_register(struct instance *i, struct mmc_driver_ops *o,
+ struct mmc_driver_params *p);
+
+The struct mmc_driver_params will have to be dynamic in some cases, but the
+driver shouldn't modify it's contents elsewhere than in probe() call.
+
+Next, since the MMC drivers will now be consistently registered into the driver
+tree from board file, the functions "board_mmc_init()" and "cpu_mmc_init()" will
+disappear altogether.
+
+As for the legacy drivers, these will either be converted or removed altogether.
+
+III) Analysis of in-tree drivers
+--------------------------------
+
+ 1) arm_pl180_mmci.c
+ -------------------
+ Follows the new API and also has a good encapsulation of the whole driver. The

+Net system analysis
+===================
+Marek Vasut <marek.vasut@gmail.com>
+2012-03-03
+
+I) Overview
+-----------
+
+The networking subsystem already supports multiple devices. Therefore the
+conversion shall not be very hard.
+
+The network subsystem is operated from net/eth.c, which tracks all registered
+ethernet interfaces and calls their particular functions registered via
+eth_register().
+
+The eth_register() is called from the network driver initialization function,
+which in turn is called most often either from "board_net_init()" or
+"cpu_net_init()". This function has one important argument, which is the
+"struct eth_device", defined at include/net.h:
+
+struct eth_device {
+ /* DRIVER: Name of the device */
+ char name[NAMESIZE];
+ /* DRIVER: MAC address */
+ unsigned char enetaddr[6];
+ /* DRIVER: Register base address */
+ int iobase;
+ /* CORE: state of the device */
+ int state;
+
+ /* DRIVER: Device initialization function */
+ int (*init) (struct eth_device*, bd_t*);
+ /* DRIVER: Function for sending packets */
+ int (*send) (struct eth_device*, volatile void* packet, int length);
+ /* DRIVER: Function for receiving packets */
+ int (*recv) (struct eth_device*);
+ /* DRIVER: Function to cease operation of the device */
+ void (*halt) (struct eth_device*);
+ /* DRIVER: Function to send multicast packet (OPTIONAL) */
+ int (*mcast) (struct eth_device*, u32 ip, u8 set);
+ /* DRIVER: Function to change ethernet MAC address */
+ int (*write_hwaddr) (struct eth_device*);
+ /* CORE: Next device in the linked list of devices managed by net core */
+ struct eth_device *next;
+ /* CORE: Device index */
+ int index;
+ /* DRIVER: Driver's private data */
+ void *priv;
+};
+
+This structure defines the particular driver, though also contains elements that
+should not be exposed to the driver, like core state.
+
+Small, but important part of the networking subsystem is the PHY management
+layer, whose drivers are contained in drivers/net/phy. These drivers register in
+a very similar manner to network drivers, by calling "phy_register()" with the
+argument of "struct phy_driver":
+
+struct phy_driver {
+ /* DRIVER: Name of the PHY driver */
+ char *name;
+ /* DRIVER: UID of the PHY driver */
+ unsigned int uid;
+ /* DRIVER: Mask for UID of the PHY driver */
+ unsigned int mask;
+ /* DRIVER: MMDS of the PHY driver */
+ unsigned int mmds;
+ /* DRIVER: Features the PHY driver supports */
+ u32 features;
+ /* DRIVER: Initialize the PHY hardware */
+ int (*probe)(struct phy_device *phydev);
+ /* DRIVER: Reconfigure the PHY hardware */
+ int (*config)(struct phy_device *phydev);
+ /* DRIVER: Turn on the PHY hardware, allow it to send/receive */
+ int (*startup)(struct phy_device *phydev);
+ /* DRIVER: Turn off the PHY hardware */
+ int (*shutdown)(struct phy_device *phydev);
+ /* CORE: Allows this driver to be part of list of drivers */
+ struct list_head list;
+};
+
+II) Approach
+------------
+
+To convert the elements of network subsystem to proper driver model method, the
+"struct eth_device" will have to be split into multiple components. The first
+will be a structure defining the driver operations:
+
+struct eth_driver_ops {
+ int (*init)(struct instance*, bd_t*);
+ int (*send)(struct instance*, void *packet, int length);
+ int (*recv)(struct instance*);
+ void (*halt)(struct instance*);
+ int (*mcast)(struct instance*, u32 ip, u8 set);
+ int (*write_hwaddr)(struct instance*);
+};
+
+Next, there'll be platform data which will be per-driver and will replace the
+"priv" part of "struct eth_device". Last part will be the per-device core state.
+
+With regards to the PHY part of the API, the "struct phy_driver" is almost ready
+to be used with the new driver model approach. The only change will be the
+replacement of per-driver initialization functions and removal of
+"phy_register()" function in favor or driver model approach.

+===============================
+PCI subsystem analysis
+======================
+
+Pavel Herrmann <morpheus.ibis@gmail.com>
+2012-03-17
+
+I) Overview
+-----------
+
+ U-Boot already supports multiple PCI busses, stored in a linked-list of
+ pci_controller structures. This structure contains generic driver data, bus
+ interface operations and private data for the driver.
+
+ Bus interface operations for PCI are (names are self-explanatory):
+
+ read_byte()
+ read_word()
+ read_dword()
+ write_byte()
+ write_word()
+ write_dword()
+
+ Each driver has to implement dword operations, and either implement word and
+ byte operations, or use shared $operation_config_$type_via_dword (eg.
+ read_config_byte_via_dword and similar) function. These functions are used
+ for config space I/O (read_config_dword and similar functions of the PCI
+ subsystem), which is used to configure the connected devices for standard MMIO
+ operations. All data transfers by respective device drivers are then done by
+ MMIO
+
+ Each driver also defines a separate init function, which has unique symbol
+ name, and thus more drivers can be compiled in without colliding. This init
+ function is typically called from pci_init_board(), different for each
+ particular board.
+
+ Some boards also define a function called fixup_irq, which gets called after
+ scanning the PCI bus for devices, and should dismiss any interrupts.
+
+ Several drivers are also located in arch/ and should be moved to drivers/pci.
+
+II) Approach
+------------
+
+ The pci_controller structure needs to be broken down to fit the new driver
+ model. Due to a large number of members, this will be done through three
+ distinct accessors, one for memory regions, one for config table and one for
+ everything else. That will make the pci_ops structure look like this:
+
+ struct pci_ops {
+ int (*read_byte)(struct instance *bus, pci_dev_t *dev, int addr,
+ u8 *buf);
+ int (*read_word)(struct instance *bus, pci_dev_t *dev, int addr,
+ u16 *buf);
+ int (*read_dword)(struct instance *bus, pci_dev_t *dev, int addr,
+ u32 *buf);
+ int (*write_byte)(struct instance *bus, pci_dev_t *dev, int addr,
+ u8 val);
+ int (*write_byte)(struct instance *bus, pci_dev_t *dev, int addr,
+ u8 val);
+ int (*write_dword)(struct instance *bus, pci_dev_t *dev, int addr,
+ u32 val);
+ void (*fixup_irq)(struct instance *bus, pci_dev_t *dev);
+ struct pci_region* (*get_region)(struct instance *, uint num);
+ struct pci_config_table* (*get_cfg_table)(struct instance *bus);
+ uint (*get_option)(struct instance * bus, enum pci_option_code op);
+ }
+
+ enum pci_option_code {
+ PCI_OPT_BUS_NUMBER=0,
+ PCI_OPT_REGION_COUNT,
+ PCI_OPT_INDIRECT_TYPE,
+ PCI_OPT_AUTO_MEM,
+ PCI_OPT_AUTO_IO,
+ PCI_OPT_AUTO_PREFETCH,
+ PCI_OPT_AUTO_FB,
+ PCI_OPT_CURRENT_BUS,
+ PCI_OPT_CFG_ADDR,
+ }
+
+ The return value for get_option will be an unsigned integer value for any
+ option code. If the option currently is a pointer to pci_region, it will
+ return an index for get_region function. Special case has to be made for
+ PCI_OPT_CFG_ADDR, which should be interpreted as a pointer, but it is only
+ used for equality in find_hose_by_cfg_addr, and thus can be returned as an
+ uint. Other function using cfg_addr value are read/write functions for
+ specific drivers (especially ops for indirect bridges), and thus have access
+ to private_data of the driver instance.
+
+ The config table accessor will return a pointer to a NULL-terminated array of
+ pci_config_table, which is supplied by the board in platform_data, or NULL if
+ the board didn't specify one. This table is used to override PnP
+ auto-initialization, or to specific initialization functions for non-PNP
+ devices.
+
+ Transparent PCI-PCI bridges will get their own driver, and will forward all
+ operations to operations of their parent bus. This however makes it
+ impossible to use instances to identify devices, as not all devices will be
+ directly visible to the respective bus driver.
+
+ Init functions of controller drivers will be moved to their respective
+ probe() functions, in accordance to the driver model.
+
+ The PCI core will handle all mapping functions currently found in pci.c, as
+ well as proxy functions for read/write operations of the drivers. The PCI
+ core will also handle bus scanning and device configuration.
+
+ The PnP helper functions currently in pci_auto.c will also be a part of PCI
+ core, but they will be exposed only to PCI controller drivers, not to other
+ device drivers.
+
+ The PCI API for device drivers will remain largely unchanged, most drivers
+ will require no changes at all, and all modifications will be limited to
+ changing the pci_controlle into instance*.

+PCMCIA analysis
+===============
+Viktor Krivak <viktor.krivak@gmail.com>
+2012-03-17
+
+I) Overview
+-----------
+
+ U-boot implements only 2 methods to interoperate with pcmcia. One to turn
+ device on and other to turn device off. Names of these methods are usually
+ pcmcia_on() and pcmcia_off() without any parameters. Some files in driver
+ directory implements only internal API. These methods aren't used outside
+ driver directory and they are not converted to new driver model.
+
+II) Approach
+-----------
+
+ 1) New API
+ ----------
+
+ Current API is preserved and all internal methods are hiden.
+
+ struct ops {
+ void (*pcmcia_on)(struct instance *i);
+ void (*pcmcia_off)(struct instance *i);
+ }
+
+ 2) Conversion
+ -------------
+
+ In header file pcmcia.h are some other variables which are used for
+ additional configuration. But all have to be moved to platform data or to
+ specific driver implementation.
+
+ 3) Platform data
+ ----------------
+
+ Many boards have custom implementation of internal API. Pointers to these
+ methods are stored in platform_data. But the most implementations for Intel
+ 82365 and compatible PC Card controllers and Yenta-compatible
+ PCI-to-CardBus controllers implement whole API per board. In these cases
+ pcmcia_on() and pcmcia_off() behave only as wrappers and call specific
+ board methods.
+
+III) Analysis of in-tree drivers
+--------------------------------
+
+ 1) i82365.c
+ -----------
+ Driver methods have different name i82365_init() and i82365_exit but
+ all functionality is the same. Board files board/atc/ti113x.c and
+ board/cpc45/pd67290.c use their own implementation of these method.
+ In this case all methods in driver behave only as wrappers.
+
+ 2) marubun_pcmcia.c
+ -------------------
+ Meets standard API behaviour. Simple conversion.
+
+ 3) mpc8xx_pcmcia.c
+ ------------------
+ Meets standard API behaviour. Simple conversion.
+
+ 4) rpx_pcmcia.c
+ ---------------
+ Implements only internal API used in other drivers. Non of methods
+ implemented here are used outside driver model.
+
+ 5) ti_pci1410a.c
+ ----------------
+ Has different API but methods in this file are never called. Probably
+ dead code.
+
+ 6)tqm8xx_pcmcia.c
+ -----------------
+ Implements only internal API used in other drivers. Non of methods
+ implemented here are used outside driver model.

+2012-03-09
+
+I) Overview
+-----------
+
+ 1) Actual state
+ ---------------
+
+ At this moment power doesn't contain API. There are many methods for
+ initialization of some board specific functions but only few does what is
+ expected. Basically only one file contains something meaningful for this
+ driver.
+
+ 2) Current implementation
+ -------------------------
+
+ In file twl6030.c are methods twl6030_stop_usb_charging() and
+ twl6030_start_usb_charging() for start and stop charging from USB. There are
+ also methods to get information about battery state and initialization of
+ battery charging. Only these methods are used in converted API.
+
+
+II) Approach
+------------
+
+ 1) New API
+ ----------
+
+ New API implements only functions specific for managing power. All board
+ specific init methods are moved to other files. Name of methods are
+ self-explanatory.
+
+ struct ops {
+ void (*start_usb_charging)(struct instance *i);
+ void (*stop_usb_charging)(struct instance *i);
+ int (*get_battery_current)(struct instance *i);
+ int (*get_battery_voltage)(struct instance *i);
+ void (*init_battery_charging)(struct instance *i);
+ }
+
+ 2) Conversions of other methods
+ -------------------------------
+
+ Methods that can't be converted to new API are moved to board file or to
+ special file for board hacks.
+
+III) Analysis of in-tree drivers
+--------------------------------
+
+ 1) ftpmu010.c
+ -------------
+ All methods of this file are moved to another location.
+ void ftpmu010_32768osc_enable(void): Move to boards hacks
+ void ftpmu010_mfpsr_select_dev(unsigned int dev): Move to board file
+ arch/nds32/lib/board.c

+ arch/nds32/lib/board.c
+ void ftpmu010_sdramhtc_set(unsigned int val): Move to board file
+ arch/nds32/lib/board.c
+
+ 2) twl4030.c
+ ------------
+ All methods of this file are moved to another location.
+ void twl4030_power_reset_init(void): Move to board hacks
+ void twl4030_pmrecv_vsel_cfg(u8 vsel_reg, u8 vsel_val, u8 dev_grp,
+ u8 dev_grp_sel): Move to board hacks
+ void twl4030_power_init(void): Move to board hacks
+ void twl4030_power_mmc_init(void): Move to board hacks
+
+ 3) twl6030.c
+ ------------
+ Some methods are converted to new API and rest are moved to another location.
+ void twl6030_stop_usb_charging(void): Convert to new API
+ void twl6030_start_usb_charging(void): Convert to new API
+ int twl6030_get_battery_current(void): Convert to new API
+ int twl6030_get_battery_voltage(void): Convert to new API
+ void twl6030_init_battery_charging(void): Convert to new API
+ void twl6030_power_mmc_init(): Move to board file

+RTC device subsystem analysis
+=============================
+
+Tomas Hlavacek <tmshlvck@gmail.com>
+2012-03-10
+
+I) Overview
+-----------
+
+U-Boot currently implements one common API for RTC devices. The interface
+is defined in include/rtc.h and comprises of functions and structures:
+
+ struct rtc_time {
+ int tm_sec;
+ int tm_min;
+ int tm_hour;
+ int tm_mday;
+ int tm_mon;
+ int tm_year;
+ int tm_wday;
+ int tm_yday;
+ int tm_isdst;
+ };
+
+ int rtc_get (struct rtc_time *);
+ int rtc_set (struct rtc_time *);
+ void rtc_reset (void);
+
+The functions are implemented by a proper device driver in drivers/rtc
+directory and the driver to be compiled in is selected in a Makefile.
+Drivers are mutually exclusive.
+
+Drivers depends on date code in drivers/rtc/date.c and naturally on board
+specific data.
+
+II) Approach
+------------
+
+ 1) New API
+ ----------
+ In the UDM each rtc driver would register itself by a function
+
+ int rtc_device_register(struct instance *i,
+ struct rtc_device_ops *o);
+
+ The structure being defined as follows:
+
+ struct rtc_device_ops {
+ int (*get_time)(struct instance *i, struct rtc_time *t);
+ int (*set_time)(struct instance *i, struct rtc_time *t);
+ int (*reset)(struct instance *i);
+ };
+
+
+ 2) Conversion thougths
+ ----------------------
+ U-Boot RTC drivers exports the same functions and therefore the conversion
+ of the drivers is straight-forward. There is no initialization needed.

+Serial I/O analysis
+===================
+Marek Vasut <marek.vasut@gmail.com>
+2012-02-20
+
+I) Overview
+-----------
+
+The serial port support currently requires the driver to export the following
+functions:
+
+ serial_putc() ...... Output a character
+ serial_puts() ...... Output string, often done using serial_putc()
+ serial_tstc() ...... Test if incoming character is in a buffer
+ serial_getc() ...... Retrieve incoming character
+ serial_setbrg() .... Configure port options
+ serial_init() ...... Initialize the hardware
+
+The simpliest implementation, supporting only one port, simply defines these six
+functions and calls them. Such calls are scattered all around U-Boot, especiall
+serial_putc(), serial_puts(), serial_tstc() and serial_getc(). The serial_init()
+and serial_setbrg() are often called from platform-dependent places.
+
+It's important to consider current implementation of CONFIG_SERIAL_MULTI though.
+This resides in common/serial.c and behaves as a multiplexer for serial ports.
+This, by calling serial_assign(), allows user to switch I/O from one serial port
+to another. Though the environmental variables "stdin", "stdout", "stderr"
+remain set to "serial".
+
+These variables are managed by the IOMUX. This resides in common/iomux.c and
+manages all console input/output from U-Boot. For serial port, only one IOMUX is
+always registered, called "serial" and the switching of different serial ports
+is done by code in common/serial.c.
+
+On a final note, it's important to mention function default_serial_console(),
+which is platform specific and reports the default serial console for the
+platform, unless proper environment variable overrides this.
+
+II) Approach
+------------
+
+Drivers not using CONFIG_SERIAL_MULTI already will have to be converted to
+similar approach. The probe() function of a driver will call a function
+registering the driver with a STDIO subsystem core, stdio_device_register().
+
+The serial_init() function will now be replaced by probe() function of the
+driver, the rest of the components of the driver will be converted to standard
+STDIO driver calls. See [ UDM-stdio.txt ] for details.
+
+The serial_setbrg() function depends on global data pointer. This is wrong,
+since there is likely to be user willing to configure different baudrate on two
+different serial ports. The function will be replaced with STDIO's "conf()"
+call, with STDIO_CONFIG_SERIAL_BAUDRATE argument.
+
+III) Analysis of in-tree drivers

+SPI analysis
+============
+Viktor Krivak <viktor.krivak@gmail.com>
+2012-03-03
+
+I) Overview
+-----------
+
+ 1) The SPI driver
+ -----------------
+
+ At this moment U-Boot provides standard API that consist of 7 functions:
+
+ void spi_init(void);
+ struct spi_slave *spi_setup_slave(unsigned int bus, unsigned int cs,
+ unsigned int max_hz, unsigned int mode);
+ void spi_free_slave(struct spi_slave *slave);
+ int spi_claim_bus(struct spi_slave *slave);
+ void spi_release_bus(struct spi_slave *slave);
+ int spi_xfer(struct spi_slave *slave, unsigned int bitlen,
+ const void *dout, void *din, unsigned long flags);
+ int spi_cs_is_valid(unsigned int bus, unsigned int cs);
+ void spi_cs_activate(struct spi_slave *slave);
+ void spi_cs_deactivate(struct spi_slave *slave);
+ void spi_set_speed(struct spi_slave *slave, uint hz);
+
+ Method spi_init() is usually empty. All necessary configuration are sets by
+ spi_setup_slave(). But this configuration is usually stored only in memory.
+ No real hardware sets are made. All hardware settings are provided by method
+ spi_claim_bus(). This method claims the bus and it can't be claimed again
+ until it's release. That's mean all calls of method spi_claim_bus() will
+ fail. But lots of cpu implementation don't meet this behaviour.
+ Method spi_release_bus() does exact opposite. It release bus directly by
+ some hardware sets. spi_free_slave() only free memory allocated by
+ spi_setup_slave(). Method spi_xfer() do actually read and write operation
+ throw specified bus and cs. Other methods are self explanatory.
+
+ 2) Current limitations
+ ----------------------
+
+ Theoretically at this moment api allows use more then one bus per device at
+ the time. But in real this can be achieved only when all buses have their
+ own base addresses in memory.
+
+
+II) Approach
+------------
+
+ 1) Claiming bus
+ ---------------
+
+ The current api cannot be used because struct spi_slave have to be in
+ private data. In that case user are prohibited to use different bus on one
+ device at same time. But when base memory address for bus are different.
+ It's possible make more instance of this driver. Otherwise it can't can be
+ done because of hardware limitation.
+
+ 2) API change
+ -------------
+
+ Method spi_init() is moved to probe. Methods spi_setup_slave() and
+ spi_claim_bus() are joined to one method. This method checks if desired bus
+ exists and is available then configure necessary hardware and claims bus.
+ Method spi_release_bus() and spi_free_slave() are also joined to meet this
+ new approach. Other function remain same. Only struct spi_slave was change
+ to instance.
+
+ struct ops {
+ int (*spi_request_bus)(struct instance *i, unsigned int bus,
+ unsigned int cs, unsigned int max_hz,
+ unsigned int mode);
+ void (*spi_release_bus)(struct instance *i);
+ int (*spi_xfer) (struct instance *i, unsigned int bitlen,
+ const void *dout, void *din, unsigned long flags);
+ int (*spi_cs_is_valid)(struct instance *i, unsigned int bus,
+ unsigned int cs);
+ void (*spi_cs_activate)(struct instance *i);
+ void (*spi_cs_deactivate)(struct instance *i);
+ void (*spi_set_speed)(struct instance *i, uint hz);
+ }
+
+ 3) Legacy API
+ -------------
+
+ To easy conversion of the whole driver. Original and new api can exist next
+ to each other. New API is designed to be only a wrapper that extracts
+ necessary information from private_data and use old api. When driver can
+ use more than one bus at the time. New API require multiple instance. One
+ for each bus. In this case spi_slave have to be copied in each instance.
+
+ 4) Conversion TIME-LINE
+ -----------------------
+
+ To prevent build corruption api conversion have to be processed in several
+ independent steps. In first step all old API methods are renamed. After that
+ new API and core function are implemented. Next step is conversion of all
+ board init methods to set platform data. After all these steps it is possible
+ to start conversion of all remaining calls. This procedure guarantees that
+ build procedure and binaries are never broken.
+

+I/O system analysis
+===================
+Marek Vasut <marek.vasut@gmail.com>
+2012-02-20
+
+I) Overview
+-----------
+
+The console input and output is currently done using the STDIO subsystem in
+U-Boot. The design of this subsystem is already flexible enough to be easily
+converted to new driver model approach. Minor changes will need to be done
+though.
+
+Each device that wants to register with STDIO subsystem has to define struct
+stdio_dev, defined in include/stdio_dev.h and containing the following fields:
+
+struct stdio_dev {
+ int flags; /* Device flags: input/output/system */
+ int ext; /* Supported extensions */
+ char name[16]; /* Device name */
+
+/* GENERAL functions */
+
+ int (*start) (void); /* To start the device */
+ int (*stop) (void); /* To stop the device */
+
+/* OUTPUT functions */
+
+ void (*putc) (const char c); /* To put a char */
+ void (*puts) (const char *s); /* To put a string (accelerator) */
+
+/* INPUT functions */
+
+ int (*tstc) (void); /* To test if a char is ready... */
+ int (*getc) (void); /* To get that char */
+
+/* Other functions */
+
+ void *priv; /* Private extensions */
+ struct list_head list;
+};
+
+Currently used flags are DEV_FLAGS_INPUT, DEV_FLAGS_OUTPUT and DEV_FLAGS_SYSTEM,
+extensions being only one, the DEV_EXT_VIDEO.
+
+The private extensions are now used as a per-device carrier of private data and
+finally list allows this structure to be a member of linked list of STDIO
+devices.
+
+The STDIN, STDOUT and STDERR routing is handled by environment variables
+"stdin", "stdout" and "stderr". By configuring the variable to the name of a
+driver, functions of such driver are called to execute that particular
+operation.
+
+II) Approach
+------------
+
+ 1) Similarity of serial, video and keyboard drivers
+ ---------------------------------------------------
+
+ All of these drivers can be unified under the STDIO subsystem if modified
+ slightly. The serial drivers basically define both input and output functions
+ and need function to configure baudrate. The keyboard drivers provide only
+ input. On the other hand, video drivers provide output, but need to be
+ configured in certain way. This configuration might be dynamic, therefore the
+ STDIO has to be modified to provide such flexibility.
+
+ 2) Unification of serial, video and keyboard drivers
+ ----------------------------------------------------
+
+ Every STDIO device would register a structure containing operation it supports
+ with the STDIO core by calling:
+
+ int stdio_device_register(struct instance *i, struct stdio_device_ops *o);
+
+ The structure being defined as follows:
+
+ struct stdio_device_ops {
+ void (*putc)(struct instance *i, const char c);
+ void (*puts)(struct instance *i, const char *s); /* OPTIONAL */
+
+ int (*tstc)(struct instance *i);
+ int (*getc)(struct instance *i);
+
+ int (*init)(struct instance *i);
+ int (*exit)(struct instance *i);
+ int (*conf)(struct instance *i, enum stdio_config c, const void *data);
+ };
+
+ The "putc()" function will emit a character, the "puts()" function will emit a
+ string. If both of these are set to NULL, the device is considered STDIN only,
+ aka input only device.
+
+ The "getc()" retrieves a character from a STDIN device, while "tstc()" tests
+ if there is a character in the buffer of STDIN device. In case these two are
+ set to NULL, this device is STDOUT / STDERR device.
+
+ Setting all "putc()", "puts()", "getc()" and "tstc()" calls to NULL isn't an
+ error condition, though such device does nothing. By instroducing tests for
+ these functions being NULL, the "flags" and "ext" fields from original struct
+ stdio_dev can be eliminated.
+
+ The "init()" and "exit()" calls are replacement for "start()" and "exit()"
+ calls in the old approach. The "priv" part of the old struct stdio_dev will be
+ replaced by common private data in the driver model and the struct list_head
+ list will be eliminated by introducing common STDIO core, that tracks all the
+ STDIO devices.
+
+ Lastly, the "conf()" call will allow the user to configure various options of
+ the driver. The enum stdio_config contains all possible configuration options
+ available to the STDIO devices, const void *data being the argument to be
+ configured. Currently, the enum stdio_config will contain at least the
+ following options:
+
+ enum stdio_config {
+ STDIO_CONFIG_SERIAL_BAUDRATE,
+ };
+
+ 3) Transformation of stdio routing
+ ----------------------------------
+
+ By allowing multiple instances of drivers, the environment variables "stdin",
+ "stdout" and "stderr" can no longer be set to the name of the driver.
+ Therefore the STDIO core, tracking all of the STDIO devices in the system will
+ need to have a small amount of internal data for each device:
+
+ struct stdio_device_node {
+ struct instance *i;
+ struct stdio_device_ops *ops;
+ uint8_t id;
+ uint8_t flags;
+ struct list_head list;
+ }
+
+ The "id" is the order of the instance of the same driver. The "flags" variable
+ allows multiple drivers to be used at the same time and even for different
+ purpose. The following flags will be defined:
+
+ STDIO_FLG_STDIN ..... This device will be used as an input device. All input
+ from all devices with this flag set will be received
+ and passed to the upper layers.
+ STDIO_FLG_STDOUT .... This device will be used as an output device. All
+ output sent to stdout will be routed to all devices
+ with this flag set.
+ STDIO_FLG_STDERR .... This device will be used as an standard error output
+ device. All output sent to stderr will be routed to
+ all devices with this flag set.
+
+ The "list" member of this structure allows to have a linked list of all
+ registered STDIO devices.
+
+III) Analysis of in-tree drivers

+For in-depth analysis of keyboard drivers, refer to [ UDM-keyboard.txt ].

+TPM system analysis
+===================
+Marek Vasut <marek.vasut@gmail.com>
+2012-02-23
+
+I) Overview
+-----------
+
+There is currently only one TPM chip driver available and therefore the API
+controlling it is very much based on this. The API is very simple:
+
+ int tis_open(void);
+ int tis_close(void);
+ int tis_sendrecv(const u8 *sendbuf, size_t send_size,
+ u8 *recvbuf, size_t *recv_len);
+
+The command operating the TPM chip only provides operations to send and receive
+bytes from the chip.
+
+II) Approach
+------------
+
+The API can't be generalised too much considering there's only one TPM chip
+supported. But it's a good idea to split the tis_sendrecv() function in two
+functions. Therefore the new API will use register the TPM chip by calling:
+
+ tpm_device_register(struct instance *i, const struct tpm_ops *ops);
+
+And the struct tpm_ops will contain the following members:
+
+ struct tpm_ops {
+ int (*tpm_open)(struct instance *i);
+ int (*tpm_close)(struct instance *i);
+ int (*tpm_send)(const uint8_t *buf, const size_t size);
+ int (*tpm_recv)(uint8_t *buf, size_t *size);
+ };
+
+The behaviour of "tpm_open()" and "tpm_close()" will basically copy the
+behaviour of "tis_open()" and "tis_close()". The "tpm_send()" will be based on
+the "tis_senddata()" and "tis_recv()" will be based on "tis_readresponse()".
+
+III) Analysis of in-tree drivers
+--------------------------------
+
+There is only one in-tree driver present, the "drivers/tpm/generic_lpc_tpm.c",
+which will be simply converted as outlined in previous chapter.

+TWserial device subsystem analysis
+==================================
+
+Tomas Hlavacek<tmshlvck@gmail.com>
+2012-03-21
+
+I) Overview
+-----------
+
+U-Boot currently implements one common API for TWSerial devices. The interface
+is defined in include/tws.h and comprises of functions:
+
+ int tws_read(uchar *buffer, int len);
+ int tws_write(uchar *buffer, int len);
+
+The functions are implemented by a proper device driver in drivers/twserial
+directory and the driver to be compiled in is selected in a Makefile. There is
+only one driver present now.
+
+The driver depends on ad-hoc code in board specific data, namely functions:
+
+ void tws_ce(unsigned bit);
+ void tws_wr(unsigned bit);
+ void tws_clk(unsigned bit);
+ void tws_data(unsigned bit);
+ unsigned tws_data_read(void);
+ void tws_data_config_output(unsigned output);
+
+implemented in include/configs/inka4x0.h .
+
+II) Approach
+------------
+
+ U-Boot TWserial drivers exports two simple functions and therefore the conversion
+ of the driver and creating a core for it is not needed. It should be consolidated
+ with include/configs/inka4x0.h and taken to the misc/ dir.
+
+
+III) Analysis of in-tree drivers
+--------------------------------
+
+ 1) drivers/twserial/soft_tws.c
+ ------------------------------
+ The driver is the only TWserial driver. The ad-hoc part in
+ include/configs/inka4x0.h and the core soft_tws driver should be consolidated
+ to one compact driver and moved to misc/ .

+USB analysis
+============
+Marek Vasut <marek.vasut@gmail.com>
+2012-02-16
+
+I) Overview
+-----------
+
+ 1) The USB Host driver
+ ----------------------
+ There are basically four or five USB host drivers. All such drivers currently
+ provide at least the following fuctions:
+
+ usb_lowlevel_init() ... Do the initialization of the USB controller hardware
+ usb_lowlevel_stop() ... Do the shutdown of the USB controller hardware
+
+ usb_event_poll() ...... Poll interrupt from USB device, often used by KBD
+
+ submit_control_msg() .. Submit message via Control endpoint
+ submit_int_msg() ...... Submit message via Interrupt endpoint
+ submit_bulk_msg() ..... Submit message via Bulk endpoint
+
+
+ This allows for the host driver to be easily abstracted.
+
+ 2) The USB hierarchy
+ --------------------
+
+ In the current implementation, the USB Host driver provides operations to
+ communicate via the USB bus. This is realised by providing access to a USB
+ root port to which an USB root hub is attached. The USB bus is scanned and for
+ each newly found device, a struct usb_device is allocated. See common/usb.c
+ and include/usb.h for details.
+
+II) Approach
+------------
+
+ 1) The USB Host driver
+ ----------------------
+
+ Converting the host driver will follow the classic driver model consideration.
+ Though, the host driver will have to call a function that registers a root
+ port with the USB core in it's probe() function, let's call this function
+
+ usb_register_root_port(&ops);
+
+ This will allow the USB core to track all available root ports. The ops
+ parameter will contain structure describing operations supported by the root
+ port:
+
+ struct usb_port_ops {
+ void (*usb_event_poll)();
+ int (*submit_control_msg)();
+ int (*submit_int_msg)();
+ int (*submit_bulk_msg)();
+ }
+
+ 2) The USB hierarchy and hub drivers
+ ------------------------------------
+
+ Converting the USB heirarchy should be fairy simple, considering the already
+ dynamic nature of the implementation. The current usb_hub_device structure
+ will have to be converted to a struct instance. Every such instance will
+ contain components of struct usb_device and struct usb_hub_device in it's
+ private data, providing only accessors in order to properly encapsulate the
+ driver.
+
+ By registering the root port, the USB framework will instantiate a USB hub
+ driver, which is always present, the root hub. The root hub and any subsequent
+ hub instance is represented by struct instance and it's private data contain
+ amongst others common bits from struct usb_device.
+
+ Note the USB hub driver is partly defying the usual method of registering a
+ set of callbacks to a particular core driver. Instead, a static set of
+ functions is defined and the USB hub instance is passed to those. This creates
+ certain restrictions as of how the USB hub driver looks, but considering the
+ specification for USB hub is given and a different type of USB hub won't ever
+ exist, this approach is ok:
+
+ - Report how many ports does this hub have:
+ uint get_nr_ports(struct instance *hub);
+ - Get pointer to device connected to a port:
+ struct instance *(*get_child)(struct instance *hub, int port);
+ - Instantiate and configure device on port:
+ struct instance *(*enum_dev_on_port)(struct instance *hub, int port);
+
+ 3) USB device drivers
+ ---------------------
+
+ The USB device driver, in turn, will have to register various ops structures
+ with certain cores. For example, USB disc driver will have to register it's
+ ops with core handling USB discs etc.

+Video output analysis
+=====================
+Marek Vasut <marek.vasut@gmail.com>
+2012-02-20
+
+I) Overview
+-----------
+
+The video drivers are most often registered with video subsystem. This subsystem
+often expects to be allowed access to framebuffer of certain parameters. This
+subsystem also provides calls for STDIO subsystem to allow it to output
+characters on the screen. For this part, see [ UDM-stdio.txt ].
+
+Therefore the API has two parts, the video driver part and the part where the
+video driver core registers with STDIO API.
+
+The video driver part will follow the current cfb_console approach, though
+allowing it to be more dynamic.
+
+II) Approach
+------------
+
+Registering the video driver into the video driver core is done by calling the
+following function from the driver probe() function:
+
+ video_device_register(struct instance *i, GraphicDevice *gd);
+
+Because the video driver core is in charge or rendering characters as well as
+bitmaps on the screen, it will in turn call stdio_device_register(i, so), where
+"i" is the same instance as the video driver's one. But "so" will be special
+static struct stdio_device_ops handling the character output.
+
+
+III) Analysis of in-tree drivers
+--------------------------------
+
+ 1) arch/powerpc/cpu/mpc8xx/video.c
+ ----------------------------------
+ This driver copies the cfb_console [ see drivers/video/cfb_console.c ]
+ approach and acts only as a STDIO device. Therefore there are currently two
+ possible approaches, first being the conversion of this driver to usual STDIO
+ device and second, long-term one, being conversion of this driver to video
+ driver that provides console.
+
+ 2) arch/x86/lib/video.c
+ -----------------------
+ This driver registers two separate STDIO devices and should be therefore
+ converted as such.
+
+ 3) board/bf527-ezkit/video.c
+ ----------------------------
+ This driver seems bogus as it behaves as STDIO device, but provides no input
+ or output capabilities. It relies on DEV_EXT_VIDEO, which is no longer in use
+ or present otherwise than as a dead code/define.
+
+ 4) board/bf533-stamp/video.c
+ ----------------------------
+ This driver seems bogus as it behaves as STDIO device, but provides no input
+ or output capabilities. It relies on DEV_EXT_VIDEO, which is no longer in use
+ or present otherwise than as a dead code/define.
+
+ 5) board/bf548-ezkit/video.c
+ ----------------------------
+ This driver seems bogus as it behaves as STDIO device, but provides no input
+ or output capabilities. It relies on DEV_EXT_VIDEO, which is no longer in use
+ or present otherwise than as a dead code/define.
+

+Watchdog device subsystem analysis
+==================================
+
+Tomas Hlavacek <tmshlvck@gmail.com>
+2012-03-09
+
+I) Overview
+-----------
+
+U-Boot currently implements an API for HW watchdog devices as explicit drivers
+in drivers/watchdog directory. There are also drivers for both hardware and
+software watchdog on particular CPUs implemented in arch/*/cpu/*/cpu.c. There
+are macros in include/watchdog.h that selects between SW and HW watchdog and
+assembly SW implementation.
+
+The current common interface comprises of one set out of these two possible
+variants:
+
+ 1)
+ void watchdog_reset(void);
+ int watchdog_disable(void);
+ int watchdog_init(void);
+
+ 2)
+ void hw_watchdog_reset(void);
+ void hw_watchdog_init(void);
+
+The watchdog implementations are also spread through board/*/*.c that in
+some cases. The API and semantics is in most cases same as the above
+mentioned common functions.
+
+
+II) Approach
+------------
+
+ 1) New API
+ ----------
+
+ In the UDM each watchdog driver would register itself by a function
+
+ int watchdog_device_register(struct instance *i,
+ const struct watchdog_device_ops *o);
+
+ The structure being defined as follows:
+
+ struct watchdog_device_ops {
+ int (*disable)(struct instance *i);
+ void (*reset)(struct instance *i);
+ };
+
+ The watchdog_init() function will be dissolved into probe() function.
+
+ 2) Conversion thougths
+ ----------------------
+
+ Conversion of watchdog implementations to a new API could be divided
+ to three subsections: a) HW implementations, which are mostly compliant
+ to the above mentioned API; b) SW implementations, which are compliant
+ to the above mentioned API and c) SW implementations that are not compliant
+ to the API and has to be rectified or partially rewritten.
+
+III) Analysis of in-tree drivers
