+ CONFIG_ARM_ERRATA_716044
CONFIG_ARM_ERRATA_742230
CONFIG_ARM_ERRATA_743622
CONFIG_ARM_ERRATA_751472
exists, unlike the similar options in the Linux kernel. Do not
set these options unless they apply!
+- CPU timer options:
+ CONFIG_SYS_HZ
+
+ The frequency of the timer returned by get_timer().
+ get_timer() must operate in milliseconds and this CONFIG
+ option must be set to 1000.
+
- Linux Kernel Interface:
CONFIG_CLOCKS_IN_MHZ
boot loader that has already initialized the UART. Define this
variable to flush the UART at init time.
- CONFIG_SYS_NS16550_BROKEN_TEMT
-
- 16550 UART set the Transmitter Empty (TEMT) Bit when all output
- has finished and the transmitter is totally empty. U-Boot waits
- for this bit to be set to initialize the serial console. On some
- broken platforms this bit is not set in SPL making U-Boot to
- hang while waiting for TEMT. Define this option to avoid it.
-
- Console Interface:
Depending on board, define exactly one serial port
(requires CONFIG_CMD_MEMORY and CONFIG_MD5)
CONFIG_CMD_MEMINFO * Display detailed memory information
CONFIG_CMD_MEMORY md, mm, nm, mw, cp, cmp, crc, base,
- loop, loopw, mtest
+ loop, loopw
+ CONFIG_CMD_MEMTEST mtest
CONFIG_CMD_MISC Misc functions like sleep etc
CONFIG_CMD_MMC * MMC memory mapped support
CONFIG_CMD_MII * MII utility commands
CONFIG_SH_MMCIF_CLK
Define the clock frequency for MMCIF
+- USB Device Firmware Update (DFU) class support:
+ CONFIG_DFU_FUNCTION
+ This enables the USB portion of the DFU USB class
+
+ CONFIG_CMD_DFU
+ This enables the command "dfu" which is used to have
+ U-Boot create a DFU class device via USB. This command
+ requires that the "dfu_alt_info" environment variable be
+ set and define the alt settings to expose to the host.
+
+ CONFIG_DFU_MMC
+ This enables support for exposing (e)MMC devices via DFU.
+
+ CONFIG_DFU_NAND
+ This enables support for exposing NAND devices via DFU.
+
+ CONFIG_SYS_DFU_MAX_FILE_SIZE
+ When updating files rather than the raw storage device,
+ we use a static buffer to copy the file into and then write
+ the buffer once we've been given the whole file. Define
+ this to the maximum filesize (in bytes) for the buffer.
+ Default is 4 MiB if undefined.
+
- Journaling Flash filesystem support:
CONFIG_JFFS2_NAND, CONFIG_JFFS2_NAND_OFF, CONFIG_JFFS2_NAND_SIZE,
CONFIG_JFFS2_NAND_DEV
I2C_READ
- Code that returns TRUE if the I2C data line is high,
- FALSE if it is low.
+ Code that returns true if the I2C data line is high,
+ false if it is low.
eg: #define I2C_READ ((immr->im_cpm.cp_pbdat & PB_SDA) != 0)
I2C_SDA(bit)
- If <bit> is TRUE, sets the I2C data line high. If it
- is FALSE, it clears it (low).
+ If <bit> is true, sets the I2C data line high. If it
+ is false, it clears it (low).
eg: #define I2C_SDA(bit) \
if(bit) immr->im_cpm.cp_pbdat |= PB_SDA; \
I2C_SCL(bit)
- If <bit> is TRUE, sets the I2C clock line high. If it
- is FALSE, it clears it (low).
+ If <bit> is true, sets the I2C clock line high. If it
+ is false, it clears it (low).
eg: #define I2C_SCL(bit) \
if(bit) immr->im_cpm.cp_pbdat |= PB_SCL; \
Adds the MTD partitioning infrastructure from the Linux
kernel. Needed for UBI support.
+- UBI support
+ CONFIG_CMD_UBI
+
+ Adds commands for interacting with MTD partitions formatted
+ with the UBI flash translation layer
+
+ Requires also defining CONFIG_RBTREE
+
+ CONFIG_UBI_SILENCE_MSG
+
+ Make the verbose messages from UBI stop printing. This leaves
+ warnings and errors enabled.
+
+- UBIFS support
+ CONFIG_CMD_UBIFS
+
+ Adds commands for interacting with UBI volumes formatted as
+ UBIFS. UBIFS is read-only in u-boot.
+
+ Requires UBI support as well as CONFIG_LZO
+
+ CONFIG_UBIFS_SILENCE_MSG
+
+ Make the verbose messages from UBIFS stop printing. This leaves
+ warnings and errors enabled.
+
- SPL framework
CONFIG_SPL
Enable building of SPL globally.
Support for lib/libgeneric.o in SPL binary
CONFIG_SPL_PAD_TO
- Linker address to which the SPL should be padded before
- appending the SPL payload.
+ Image offset to which the SPL should be padded before appending
+ the SPL payload. By default, this is defined as
+ CONFIG_SPL_MAX_SIZE, or 0 if CONFIG_SPL_MAX_SIZE is undefined.
+ CONFIG_SPL_PAD_TO must be either 0, meaning to append the SPL
+ payload without any padding, or >= CONFIG_SPL_MAX_SIZE.
CONFIG_SPL_TARGET
Final target image containing SPL and payload. Some SPLs
If defined, don't allow the -f switch to env set override variable
access flags.
+- CONFIG_SYS_GENERIC_BOARD
+ This selects the architecture-generic board system instead of the
+ architecture-specific board files. It is intended to move boards
+ to this new framework over time. Defining this will disable the
+ arch/foo/lib/board.c file and use common/board_f.c and
+ common/board_r.c instead. To use this option your architecture
+ must support it (i.e. must define __HAVE_ARCH_GENERIC_BOARD in
+ its config.mk file). If you find problems enabling this option on
+ your board please report the problem and send patches!
+
+- CONFIG_SYS_SYM_OFFSETS
+ This is set by architectures that use offsets for link symbols
+ instead of absolute values. So bss_start is obtained using an
+ offset _bss_start_ofs from CONFIG_SYS_TEXT_BASE, rather than
+ directly. You should not need to touch this setting.
+
+
The following definitions that deal with the placement and management
of environment data (variable area); in general, we support the
following configurations:
environment. If redundant environment is used, it will be copied to
CONFIG_NAND_ENV_DST + CONFIG_ENV_SIZE.
+- CONFIG_ENV_IS_IN_UBI:
+
+ Define this if you have an UBI volume that you want to use for the
+ environment. This has the benefit of wear-leveling the environment
+ accesses, which is important on NAND.
+
+ - CONFIG_ENV_UBI_PART:
+
+ Define this to a string that is the mtd partition containing the UBI.
+
+ - CONFIG_ENV_UBI_VOLUME:
+
+ Define this to the name of the volume that you want to store the
+ environment in.
+
+ - CONFIG_ENV_UBI_VOLUME_REDUND:
+
+ Define this to the name of another volume to store a second copy of
+ the environment in. This will enable redundant environments in UBI.
+ It is assumed that both volumes are in the same MTD partition.
+
+ - CONFIG_UBI_SILENCE_MSG
+ - CONFIG_UBIFS_SILENCE_MSG
+
+ You will probably want to define these to avoid a really noisy system
+ when storing the env in UBI.
+
- CONFIG_SYS_SPI_INIT_OFFSET
Defines offset to the initial SPI buffer area in DPRAM. The
- CONFIG_SYS_SRIOn_MEM_SIZE:
Size of SRIO port 'n' memory region
-- CONFIG_SYS_NDFC_16
- Defined to tell the NDFC that the NAND chip is using a
- 16 bit bus.
+- CONFIG_SYS_NAND_BUSWIDTH_16BIT
+ Defined to tell the NAND controller that the NAND chip is using
+ a 16 bit bus.
+ Not all NAND drivers use this symbol.
+ Example of drivers that use it:
+ - drivers/mtd/nand/ndfc.c
+ - drivers/mtd/nand/mxc_nand.c
- CONFIG_SYS_NDFC_EBC0_CFG
Sets the EBC0_CFG register for the NDFC. If not defined
If defined, the x86 reset vector code is included. This is not
needed when U-Boot is running from Coreboot.
+- CONFIG_SYS_MPUCLK
+ Defines the MPU clock speed (in MHz).
+
+ NOTE : currently only supported on AM335x platforms.

+ * The BCM2835 SoC contains (at least) two CPUs; the VideoCore (a/k/a "GPU")
+ * and the ARM CPU. The ARM CPU is often thought of as the main CPU.
+ * However, the VideoCore actually controls the initial SoC boot, and hides
+ * much of the hardware behind a protocol. This protocol is transported
+ * using the SoC's mailbox hardware module.
+ *
+ * The mailbox hardware supports passing 32-bit values back and forth.
+ * Presumably by software convention of the firmware, the bottom 4 bits of the
+ * value are used to indicate a logical channel, and the upper 28 bits are the
+ * actual payload. Various channels exist using these simple raw messages. See
+ * https://github.com/raspberrypi/firmware/wiki/Mailboxes for a list. As an
+ * example, the messages on the power management channel are a bitmask of
+ * devices whose power should be enabled.
+ *
+ * The property mailbox channel passes messages that contain the (16-byte
+ * aligned) ARM physical address of a memory buffer. This buffer is passed to
+ * the VC for processing, is modified in-place by the VC, and the address then
+ * passed back to the ARM CPU as the response mailbox message to indicate
+ * request completion. The buffers have a generic and extensible format; each
+ * buffer contains a standard header, a list of "tags", and a terminating zero
+ * entry. Each tag contains an ID indicating its type, and length fields for
+ * generic parsing. With some limitations, an arbitrary set of tags may be
+ * combined together into a single message buffer. This file defines structs
+ * representing the header and many individual tag layouts and IDs.

+
+ANSI terminal bootmenu command
+
+The "bootmenu" command uses U-Boot menu interfaces and provides
+a simple mechanism for creating menus with different boot items.
+The cursor keys "Up" and "Down" are used for navigation through
+the items. Current active menu item is highlighted and can be
+selected using the "Enter" key. The selection of the highlighted
+menu entry invokes an U-Boot command (or a list of commands)
+associated with this menu entry.
+
+The "bootmenu" command interprets ANSI escape sequencies, so
+an ANSI terminal is required for proper menu rendering and item
+selection.
+
+The assembling of the menu is done via a set of environment variables
+"bootmenu_<num>" and "bootmenu_delay", i.e.:
+
+ bootmenu_delay=<delay>
+ bootmenu_<num>="<title>=<commands>"
+
+ <delay> is the autoboot delay in seconds, after which the first
+ menu entry will be selected automatically
+
+ <num> is the boot menu entry number, starting from zero
+
+ <title> is the text of the menu entry shown on the console
+ or on the boot screen
+
+ <commands> are commands which will be executed when a menu
+ entry is selected
+
+ (title and commands are separated by first appearance of '='
+ character in the environment variable)
+
+First (optional) argument of the "bootmenu" command is a delay specifier
+and it overrides the delay value defined by "bootmenu_delay" environment
+variable. If the environment variable "bootmenu_delay" is not set or if
+the argument of the "bootmenu" command is not specified, the default delay
+will be CONFIG_BOOTDELAY. If delay is 0, no menu entries will be shown on
+the console (or on the screen) and the command of the first menu entry will
+be called immediately. If delay is less then 0, bootmenu will be shown and
+autoboot will be disabled.
+
+Bootmenu always adds menu entry "U-Boot console" at the end of all menu
+entries specified by environment variables. When selecting this entry
+the bootmenu terminates and the usual U-Boot command prompt is presented
+to the user.
+
+Example environment:
+
+ setenv bootmenu_0 Boot 1. kernel=bootm 0x82000000 # Set first menu entry
+ setenv bootmenu_1 Boot 2. kernel=bootm 0x83000000 # Set second menu entry
+ setenv bootmenu_2 Reset board=reset # Set third menu entry
+ setenv bootmenu_3 U-Boot boot order=boot # Set fourth menu entry
+ bootmenu 20 # Run bootmenu with autoboot delay 20s
+
+
+The above example will be rendered as below
+(without decorating rectangle):
+
+┌──────────────────────────────────────────┐
+│ │
+│ *** U-Boot Boot Menu *** │
+│ │
+│ Boot 1. kernel │
+│ Boot 2. kernel │
+│ Reset board │
+│ U-Boot boot order │
+│ U-Boot console │
+│ │
+│ Hit any key to stop autoboot: 20 │
+│ Press UP/DOWN to move, ENTER to select │
+│ │
+└──────────────────────────────────────────┘
+
+Selected menu entry will be highlighted - it will have inverted
+background and text colors.
+
+To enable the "bootmenu" command add following definitions to the
+board config file:
+
+ #define CONFIG_CMD_BOOTMENU
+ #define CONFIG_MENU
+
+To run the bootmenu at startup add these additional definitions:
+
+ #define CONFIG_AUTOBOOT_KEYED
+ #define CONFIG_BOOTDELAY 30
+ #define CONFIG_MENU_SHOW
+
+When you intend to use the bootmenu on color frame buffer console,
+make sure to additionally define CONFIG_CFB_CONSOLE_ANSI in the
+board config file.
#define CONFIG_EXTRA_ENV_SETTINGS "fdtcontroladdr=10000\0"
+Build:
+
+After board configuration is done, fdt supported u-boot can be build in two ways:
+1) build the default dts which is defined from CONFIG_DEFAULT_DEVICE_TREE
+ $ make
+2) build the user specified dts file
+ $ make DEVICE_TREE=<dts-file-name>
+
Limitations
-----------
--- /dev/null
+The most frequent cause of problems when porting U-Boot to new
+hardware, or when using a sloppy port on some board, is memory errors.
+In most cases these are not caused by failing hardware, but by
+incorrect initialization of the memory controller. So it appears to
+be a good idea to always test if the memory is working correctly,
+before looking for any other potential causes of any problems.
+
+U-Boot implements 3 different approaches to perform memory tests:
+
+1. The get_ram_size() function (see "common/memsize.c").
+
+ This function is supposed to be used in each and every U-Boot port
+ determine the presence and actual size of each of the potential
+ memory banks on this piece of hardware. The code is supposed to be
+ very fast, so running it for each reboot does not hurt. It is a
+ little known and generally underrated fact that this code will also
+ catch 99% of hardware related (i. e. reliably reproducible) memory
+ errors. It is strongly recommended to always use this function, in
+ each and every port of U-Boot.
+
+2. The "mtest" command.
+
+ This is probably the best known memory test utility in U-Boot.
+ Unfortunately, it is also the most problematic, and the most
+ useless one.
+
+ There are a number of serious problems with this command:
+
+ - It is terribly slow. Running "mtest" on the whole system RAM
+ takes a _long_ time before there is any significance in the fact
+ that no errors have been found so far.
+
+ - It is difficult to configure, and to use. And any errors here
+ will reliably crash or hang your system. "mtest" is dumb and has
+ no knowledge about memory ranges that may be in use for other
+ purposes, like exception code, U-Boot code and data, stack,
+ malloc arena, video buffer, log buffer, etc. If you let it, it
+ will happily "test" all such areas, which of course will cause
+ some problems.
+
+ - It is not easy to configure and use, and a large number of
+ systems are seriously misconfigured. The original idea was to
+ test basically the whole system RAM, with only exempting the
+ areas used by U-Boot itself - on most systems these are the areas
+ used for the exception vectors (usually at the very lower end of
+ system memory) and for U-Boot (code, data, etc. - see above;
+ these are usually at the very upper end of system memory). But
+ experience has shown that a very large number of ports use
+ pretty much bogus settings of CONFIG_SYS_MEMTEST_START and
+ CONFIG_SYS_MEMTEST_END; this results in useless tests (because
+ the ranges is too small and/or badly located) or in critical
+ failures (system crashes).
+
+ Because of these issues, the "mtest" command is considered depre-
+ cated. It should not be enabled in most normal ports of U-Boot,
+ especially not in production. If you really need a memory test,
+ then see 1. and 3. above resp. below.
+
+3. The most thorough memory test facility is available as part of the
+ POST (Power-On Self Test) sub-system, see "post/drivers/memory.c".
+
+ If you really need to perform memory tests (for example, because
+ it is mandatory part of your requirement specification), then
+ enable this test which is generic and should work on all archi-
+ tectures.
+
+WARNING:
+
+It should pointed out that _all_ these memory tests have one
+fundamental, unfixable design flaw: they are based on the assumption
+that memory errors can be found by writing to and reading from memory.
+Unfortunately, this is only true for the relatively harmless, usually
+static errors like shorts between data or address lines, unconnected
+pins, etc. All the really nasty errors which will first turn your
+hair gray, only to make you tear it out later, are dynamical errors,
+which usually happen not with simple read or write cycles on the bus,
+but when performing back-to-back data transfers in burst mode. Such
+accesses usually happen only for certain DMA operations, or for heavy
+cache use (instruction fetching, cache flushing). So far I am not
+aware of any freely available code that implements a generic, and
+efficient, memory test like that. The best known test case to stress
+a system like that is to boot Linux with root file system mounted over
+NFS, and then build some larger software package natively (say,
+compile a Linux kernel on the system) - this will cause enough context
+switches, network traffic (and thus DMA transfers from the network
+controller), varying RAM use, etc. to trigger any weak spots in this
+area.
+
+Note: An attempt was made once to implement such a test to catch
+memory problems on a specific board. The code is pretty much board
+specific (for example, it includes setting specific GPIO signals to
+provide triggers for an attached logic analyzer), but you can get an
+idea how it works: see "examples/standalone/test_burst*".
+
+Note 2: Ironically enough, the "test_burst" did not catch any RAM
+errors, not a single one ever. The problems this code was supposed
+to catch did not happen when accessing the RAM, but when reading from
+NOR flash.

Read silicon Revision of the DMA module
+NAND
+====
+
+There are some OMAP3 devices out there with NAND attached. Due to the fact that
+OMAP3 ROM code can only handle 1-bit hamming ECC for accessing first page
+(place where SPL lives) we require this setup for u-boot at least when reading
+the second progam within SPL. A lot of newer NAND chips however require more
+than 1-bit ECC for the pages, some can live with 1-bit for the first page. To
+handle this we can switch to another ECC algorithm after reading the payload
+within SPL.
+
+BCH8
+----
+
+To enable hardware assisted BCH8 (8-bit BCH [Bose, Chaudhuri, Hocquenghem]) on
+OMAP3 devices we can use the BCH library in lib/bch.c. To do so add CONFIG_BCH
+to enable the library and CONFIG_NAND_OMAP_BCH8 to to enable hardware assisted
+syndrom generation to your board config.
+The NAND OOB layout is the same as in linux kernel, if the linux kernel BCH8
+implementation for OMAP3 works for you so the u-boot version should also.
+When you require the SPL to read with BCH8 there are two more configs to
+change:
+
+ * CONFIG_SYS_NAND_ECCPOS (must be the same as .eccpos in
+ GPMC_NAND_HW_BCH8_ECC_LAYOUT defined in
+ arch/arm/include/asm/arch-omap3/omap_gpmc.h)
+ * CONFIG_SYS_NAND_ECCSIZE must be 512
+ * CONFIG_SYS_NAND_ECCBYTES must be 13 for this BCH8 setup

-What: Users of the legacy miiphy_* code
-When: undetermined
+What: Remove CONFIG_CMD_MEMTEST from default list
+When: Release v2013.07
-Why: We now have a PHY library, which allows everyone to share PHY
- drivers. All new drivers should use this infrastructure, and
- all old drivers should get converted to use it.
+Why: The "mtest" command is of little practical use (if any), and
+ experience has shown that a large number of board configu-
+ rations define useless or even dangerous start and end
+ addresses. If not even the board maintainers are able to
+ figure out which memory range can be reliably tested, how can
+ we expect such from the end users? As this problem comes up
+ repeatedly, we rather do not enable this command by default,
+ so only people who know what they are doing will be confronted
+ with it.
-Who: Andy Fleming <afleming@freescale.com> and driver maintainers
+Who: Wolfgang Denk <wd@denx.de>
---------------------------
-What: boards with xxx_config targets in top level Makefile
-When: Release v2012.03
+What: Remove CONFIG_SYS_ENABLE_PADS_ALL and CONFIG_SYS_CLOCKS_ENABLE_ALL
+When: Release v2013.07
+
+Why: When set these options enable "all" of the pads and clocks found
+ on OMAP4/5 platforms, so that the Linux Kernel does not have to.
+ It has been agreed that this goes against the U-Boot design
+ philosophy and since f3f98bb0 we have not enabled more than is
+ used in U-Boot. The kernel has been updating drivers to enable
+ rather than assume pads/clocks have been enabled already. Our
+ expectation is that by v2013.07 a suitable kernel shall exist that
+ does not need these options set for a reasonable I/O set to function.
+
+Who: Tom Rini <trini@ti.com> and Sricharan R <r.sricharan@ti.com>
-Why: We have a boards.cfg file which the vast majority of boards have
- converted over to. Boards that still manually run mkconfig in the
- top level Makefile are either dead, or the maintainer doesn't care,
- or they are doing something weird/wrong that should be fixed in a
- different way, or they need to extend boards.cfg syntax (unlikely).
+---------------------------
+
+What: Users of the legacy miiphy_* code
+When: undetermined
- In any case, if no one cares about these boards to figure out how
- to make boards.cfg work, then we'll just punt them.
+Why: We now have a PHY library, which allows everyone to share PHY
+ drivers. All new drivers should use this infrastructure, and
+ all old drivers should get converted to use it.

+/*
+ * The Mass Storage Function acts as a USB Mass Storage device,
+ * appearing to the host as a disk drive or as a CD-ROM drive. In
+ * addition to providing an example of a genuinely useful composite
+ * function for a USB device, it also illustrates a technique of
+ * double-buffering for increased throughput.
+ *
+ * Function supports multiple logical units (LUNs). Backing storage
+ * for each LUN is provided by a regular file or a block device.
+ * Access for each LUN can be limited to read-only. Moreover, the
+ * function can indicate that LUN is removable and/or CD-ROM. (The
+ * later implies read-only access.)
+ *
+ * MSF is configured by specifying a fsg_config structure. It has the
+ * following fields:
+ *
+ * nluns Number of LUNs function have (anywhere from 1
+ * to FSG_MAX_LUNS which is 8).
+ * luns An array of LUN configuration values. This
+ * should be filled for each LUN that
+ * function will include (ie. for "nluns"
+ * LUNs). Each element of the array has
+ * the following fields:
+ * ->filename The path to the backing file for the LUN.
+ * Required if LUN is not marked as
+ * removable.
+ * ->ro Flag specifying access to the LUN shall be
+ * read-only. This is implied if CD-ROM
+ * emulation is enabled as well as when
+ * it was impossible to open "filename"
+ * in R/W mode.
+ * ->removable Flag specifying that LUN shall be indicated as
+ * being removable.
+ * ->cdrom Flag specifying that LUN shall be reported as
+ * being a CD-ROM.
+ *
+ * lun_name_format A printf-like format for names of the LUN
+ * devices. This determines how the
+ * directory in sysfs will be named.
+ * Unless you are using several MSFs in
+ * a single gadget (as opposed to single
+ * MSF in many configurations) you may
+ * leave it as NULL (in which case
+ * "lun%d" will be used). In the format
+ * you can use "%d" to index LUNs for
+ * MSF's with more than one LUN. (Beware
+ * that there is only one integer given
+ * as an argument for the format and
+ * specifying invalid format may cause
+ * unspecified behaviour.)
+ * thread_name Name of the kernel thread process used by the
+ * MSF. You can safely set it to NULL
+ * (in which case default "file-storage"
+ * will be used).
+ *
+ * vendor_name
+ * product_name
+ * release Information used as a reply to INQUIRY
+ * request. To use default set to NULL,
+ * NULL, 0xffff respectively. The first
+ * field should be 8 and the second 16
+ * characters or less.
+ *
+ * can_stall Set to permit function to halt bulk endpoints.
+ * Disabled on some USB devices known not
+ * to work correctly. You should set it
+ * to true.
+ *
+ * If "removable" is not set for a LUN then a backing file must be
+ * specified. If it is set, then NULL filename means the LUN's medium
+ * is not loaded (an empty string as "filename" in the fsg_config
+ * structure causes error). The CD-ROM emulation includes a single
+ * data track and no audio tracks; hence there need be only one
+ * backing file per LUN. Note also that the CD-ROM block length is
+ * set to 512 rather than the more common value 2048.
+ *
+ *
+ * MSF includes support for module parameters. If gadget using it
+ * decides to use it, the following module parameters will be
+ * available:
+ *
+ * file=filename[,filename...]
+ * Names of the files or block devices used for
+ * backing storage.
+ * ro=b[,b...] Default false, boolean for read-only access.
+ * removable=b[,b...]
+ * Default true, boolean for removable media.
+ * cdrom=b[,b...] Default false, boolean for whether to emulate
+ * a CD-ROM drive.
+ * luns=N Default N = number of filenames, number of
+ * LUNs to support.
+ * stall Default determined according to the type of
+ * USB device controller (usually true),
+ * boolean to permit the driver to halt
+ * bulk endpoints.
+ *
+ * The module parameters may be prefixed with some string. You need
+ * to consult gadget's documentation or source to verify whether it is
+ * using those module parameters and if it does what are the prefixes
+ * (look for FSG_MODULE_PARAMETERS() macro usage, what's inside it is
+ * the prefix).
+ *
+ *
+ * Requirements are modest; only a bulk-in and a bulk-out endpoint are
+ * needed. The memory requirement amounts to two 16K buffers, size
+ * configurable by a parameter. Support is included for both
+ * full-speed and high-speed operation.
+ *
+ * Note that the driver is slightly non-portable in that it assumes a
+ * single memory/DMA buffer will be useable for bulk-in, bulk-out, and
+ * interrupt-in endpoints. With most device controllers this isn't an
+ * issue, but there may be some with hardware restrictions that prevent
+ * a buffer from being used by more than one endpoint.
+ *
+ *
+ * The pathnames of the backing files and the ro settings are
+ * available in the attribute files "file" and "ro" in the lun<n> (or
+ * to be more precise in a directory which name comes from
+ * "lun_name_format" option!) subdirectory of the gadget's sysfs
+ * directory. If the "removable" option is set, writing to these
+ * files will simulate ejecting/loading the medium (writing an empty
+ * line means eject) and adjusting a write-enable tab. Changes to the
+ * ro setting are not allowed when the medium is loaded or if CD-ROM
+ * emulation is being used.
+ *
+ * When a LUN receive an "eject" SCSI request (Start/Stop Unit),
+ * if the LUN is removable, the backing file is released to simulate
+ * ejection.
+ *
+ *
+ * This function is heavily based on "File-backed Storage Gadget" by
+ * Alan Stern which in turn is heavily based on "Gadget Zero" by David
+ * Brownell. The driver's SCSI command interface was based on the
+ * "Information technology - Small Computer System Interface - 2"
+ * document from X3T9.2 Project 375D, Revision 10L, 7-SEP-93,
+ * available at <http://www.t10.org/ftp/t10/drafts/s2/s2-r10l.pdf>.
+ * The single exception is opcode 0x23 (READ FORMAT CAPACITIES), which
+ * was based on the "Universal Serial Bus Mass Storage Class UFI
+ * Command Specification" document, Revision 1.0, December 14, 1998,
+ * available at
+ * <http://www.usb.org/developers/devclass_docs/usbmass-ufi10.pdf>.

+
+
+/*
+ * Driver Design
+ *
+ * The MSF is fairly straightforward. There is a main kernel
+ * thread that handles most of the work. Interrupt routines field
+ * callbacks from the controller driver: bulk- and interrupt-request
+ * completion notifications, endpoint-0 events, and disconnect events.
+ * Completion events are passed to the main thread by wakeup calls. Many
+ * ep0 requests are handled at interrupt time, but SetInterface,
+ * SetConfiguration, and device reset requests are forwarded to the
+ * thread in the form of "exceptions" using SIGUSR1 signals (since they
+ * should interrupt any ongoing file I/O operations).
+ *
+ * The thread's main routine implements the standard command/data/status
+ * parts of a SCSI interaction. It and its subroutines are full of tests
+ * for pending signals/exceptions -- all this polling is necessary since
+ * the kernel has no setjmp/longjmp equivalents. (Maybe this is an
+ * indication that the driver really wants to be running in userspace.)
+ * An important point is that so long as the thread is alive it keeps an
+ * open reference to the backing file. This will prevent unmounting
+ * the backing file's underlying filesystem and could cause problems
+ * during system shutdown, for example. To prevent such problems, the
+ * thread catches INT, TERM, and KILL signals and converts them into
+ * an EXIT exception.
+ *
+ * In normal operation the main thread is started during the gadget's
+ * fsg_bind() callback and stopped during fsg_unbind(). But it can
+ * also exit when it receives a signal, and there's no point leaving
+ * the gadget running when the thread is dead. At of this moment, MSF
+ * provides no way to deregister the gadget when thread dies -- maybe
+ * a callback functions is needed.
+ *
+ * To provide maximum throughput, the driver uses a circular pipeline of
+ * buffer heads (struct fsg_buffhd). In principle the pipeline can be
+ * arbitrarily long; in practice the benefits don't justify having more
+ * than 2 stages (i.e., double buffering). But it helps to think of the
+ * pipeline as being a long one. Each buffer head contains a bulk-in and
+ * a bulk-out request pointer (since the buffer can be used for both
+ * output and input -- directions always are given from the host's
+ * point of view) as well as a pointer to the buffer and various state
+ * variables.
+ *
+ * Use of the pipeline follows a simple protocol. There is a variable
+ * (fsg->next_buffhd_to_fill) that points to the next buffer head to use.
+ * At any time that buffer head may still be in use from an earlier
+ * request, so each buffer head has a state variable indicating whether
+ * it is EMPTY, FULL, or BUSY. Typical use involves waiting for the
+ * buffer head to be EMPTY, filling the buffer either by file I/O or by
+ * USB I/O (during which the buffer head is BUSY), and marking the buffer
+ * head FULL when the I/O is complete. Then the buffer will be emptied
+ * (again possibly by USB I/O, during which it is marked BUSY) and
+ * finally marked EMPTY again (possibly by a completion routine).
+ *
+ * A module parameter tells the driver to avoid stalling the bulk
+ * endpoints wherever the transport specification allows. This is
+ * necessary for some UDCs like the SuperH, which cannot reliably clear a
+ * halt on a bulk endpoint. However, under certain circumstances the
+ * Bulk-only specification requires a stall. In such cases the driver
+ * will halt the endpoint and set a flag indicating that it should clear
+ * the halt in software during the next device reset. Hopefully this
+ * will permit everything to work correctly. Furthermore, although the
+ * specification allows the bulk-out endpoint to halt when the host sends
+ * too much data, implementing this would cause an unavoidable race.
+ * The driver will always use the "no-stall" approach for OUT transfers.
+ *
+ * One subtle point concerns sending status-stage responses for ep0
+ * requests. Some of these requests, such as device reset, can involve
+ * interrupting an ongoing file I/O operation, which might take an
+ * arbitrarily long time. During that delay the host might give up on
+ * the original ep0 request and issue a new one. When that happens the
+ * driver should not notify the host about completion of the original
+ * request, as the host will no longer be waiting for it. So the driver
+ * assigns to each ep0 request a unique tag, and it keeps track of the
+ * tag value of the request associated with a long-running exception
+ * (device-reset, interface-change, or configuration-change). When the
+ * exception handler is finished, the status-stage response is submitted
+ * only if the current ep0 request tag is equal to the exception request
+ * tag. Thus only the most recently received ep0 request will get a
+ * status-stage response.
+ *
+ * Warning: This driver source file is too long. It ought to be split up
+ * into a header file plus about 3 separate .c files, to handle the details
+ * of the Gadget, USB Mass Storage, and SCSI protocols.

+What is this?
+=============
+
+This tool handles building U-Boot to check that you have not broken it
+with your patch series. It can build each individual commit and report
+which boards fail on which commits, and which errors come up. It aims
+to make full use of multi-processor machines.
+
+A key feature of buildman is its output summary, which allows warnings,
+errors or image size increases in a particular commit or board to be
+quickly identified and the offending commit pinpointed. This can be a big
+help for anyone working with >10 patches at a time.
+
+
+Caveats
+=======
+
+Buildman is still in its infancy. It is already a very useful tool, but
+expect to find problems and send patches.
+
+Buildman can be stopped and restarted, in which case it will continue
+where it left off. This should happen cleanly and without side-effects.
+If not, it is a bug, for which a patch would be welcome.
+
+Buildman gets so tied up in its work that it can ignore the outside world.
+You may need to press Ctrl-C several times to quit it. Also it will print
+out various exceptions when stopped.
+
+
+Theory of Operation
+===================
+
+(please read this section in full twice or you will be perpetually confused)
+
+Buildman is a builder. It is not make, although it runs make. It does not
+produce any useful output on the terminal while building, except for
+progress information. All the output (errors, warnings and binaries if you
+are ask for them) is stored in output directories, which you can look at
+while the build is progressing, or when it is finished.
+
+Buildman produces a concise summary of which boards succeeded and failed.
+It shows which commit introduced which board failure using a simple
+red/green colour coding. Full error information can be requested, in which
+case it is de-duped and displayed against the commit that introduced the
+error. An example workflow is below.
+
+Buildman stores image size information and can report changes in image size
+from commit to commit. An example of this is below.
+
+Buildman starts multiple threads, and each thread builds for one board at
+a time. A thread starts at the first commit, configures the source for your
+board and builds it. Then it checks out the next commit and does an
+incremental build. Eventually the thread reaches the last commit and stops.
+If errors or warnings are found along the way, the thread will reconfigure
+after every commit, and your build will be very slow. This is because a
+file that produces just a warning would not normally be rebuilt in an
+incremental build.
+
+Buildman works in an entirely separate place from your U-Boot repository.
+It creates a separate working directory for each thread, and puts the
+output files in the working directory, organised by commit name and board
+name, in a two-level hierarchy.
+
+Buildman is invoked in your U-Boot directory, the one with the .git
+directory. It clones this repository into a copy for each thread, and the
+threads do not affect the state of your git repository. Any checkouts done
+by the thread affect only the working directory for that thread.
+
+Buildman automatically selects the correct toolchain for each board. You
+must supply suitable toolchains, but buildman takes care of selecting the
+right one.
+
+Buildman always builds a branch, and always builds the upstream commit as
+well, for comparison. It cannot build individual commits at present, unless
+(maybe) you point it at an empty branch. Put all your commits in a branch,
+set the branch's upstream to a valid value, and all will be well. Otherwise
+buildman will perform random actions. Use -n to check what the random
+actions might be.
+
+Buildman is optimised for building many commits at once, for many boards.
+On multi-core machines, Buildman is fast because it uses most of the
+available CPU power. When it gets to the end, or if you are building just
+a few commits or boards, it will be pretty slow. As a tip, if you don't
+plan to use your machine for anything else, you can use -T to increase the
+number of threads beyond the default.
+
+Buildman lets you build all boards, or a subset. Specify the subset using
+the board name, architecture name, SOC name, or anything else in the
+boards.cfg file. So 'at91' will build all AT91 boards (arm), powerpc will
+build all PowerPC boards.
+
+Buildman does not store intermediate object files. It optionally copies
+the binary output into a directory when a build is successful. Size
+information is always recorded. It needs a fair bit of disk space to work,
+typically 250MB per thread.
+
+
+Setting up
+==========
+
+1. Get the U-Boot source. You probably already have it, but if not these
+steps should get you started with a repo and some commits for testing.
+
+$ cd /path/to/u-boot
+$ git clone git://git.denx.de/u-boot.git .
+$ git checkout -b my-branch origin/master
+$ # Add some commits to the branch, reading for testing
+
+2. Create ~/.buildman to tell buildman where to find tool chains. As an
+example:
+
+# Buildman settings file
+
+[toolchain]
+root: /
+rest: /toolchains/*
+eldk: /opt/eldk-4.2
+
+[toolchain-alias]
+x86: i386
+blackfin: bfin
+sh: sh4
+nds32: nds32le
+openrisc: or32
+
+
+This selects the available toolchain paths. Add the base directory for
+each of your toolchains here. Buildman will search inside these directories
+and also in any '/usr' and '/usr/bin' subdirectories.
+
+Make sure the tags (here root: rest: and eldk:) are unique.
+
+The toolchain-alias section indicates that the i386 toolchain should be used
+to build x86 commits.
+
+
+2. Check the available toolchains
+
+Run this check to make sure that you have a toolchain for every architecture.

+You can see that everything is covered, even some strange ones that won't
+be used (c88 and c99). This is a feature.
+
+
+How to run it
+=============
+
+First do a dry run using the -n flag: (replace <branch> with a real, local
+branch with a valid upstream)
+
+$ ./tools/buildman/buildman -b <branch> -n
+
+If it can't detect the upstream branch, try checking out the branch, and
+doing something like 'git branch --set-upstream <branch> upstream/master'
+or something similar.
+
+As an exmmple:
+
+Dry run, so not doing much. But I would do this:
+
+Building 18 commits for 1059 boards (4 threads, 1 job per thread)

+ 49ff541 wip
+
+Total boards to build for each commit: 1059
+
+This shows that it will build all 1059 boards, using 4 threads (because
+we have a 4-core CPU). Each thread will run with -j1, meaning that each
+make job will use a single CPU. The list of commits to be built helps you
+confirm that things look about right. Notice that buildman has chosen a
+'base' directory for you, immediately above your source tree.
+
+Buildman works entirely inside the base directory, here ../lcd9b,
+creating a working directory for each thread, and creating output
+directories for each commit and board.
+
+
+Suggested Workflow
+==================
+
+To run the build for real, take off the -n:
+
+$ ./tools/buildman/buildman -b <branch>
+
+Buildman will set up some working directories, and get started. After a
+minute or so it will settle down to a steady pace, with a display like this:
+
+Building 18 commits for 1059 boards (4 threads, 1 job per thread)
+ 528 36 124 /19062 1:13:30 : SIMPC8313_SP
+
+This means that it is building 19062 board/commit combinations. So far it
+has managed to succesfully build 528. Another 36 have built with warnings,
+and 124 more didn't build at all. Buildman expects to complete the process
+in an hour and 15 minutes. Use this time to buy a faster computer.
+
+
+To find out how the build went, ask for a summary with -s. You can do this
+either before the build completes (presumably in another terminal) or or
+afterwards. Let's work through an example of how this is used:
+
+$ ./tools/buildman/buildman -b lcd9b -s
+...
+01: Merge branch 'master' of git://git.denx.de/u-boot-arm
+ powerpc: + galaxy5200_LOWBOOT
+02: tegra: Use const for pinmux_config_pingroup/table()
+03: tegra: Add display support to funcmux
+04: tegra: fdt: Add pwm binding and node
+05: tegra: fdt: Add LCD definitions for Tegra
+06: tegra: Add support for PWM
+07: tegra: Add SOC support for display/lcd
+08: tegra: Add LCD driver
+09: tegra: Add LCD support to Nvidia boards
+10: arm: Add control over cachability of memory regions
+11: lcd: Add CONFIG_LCD_ALIGNMENT to select frame buffer alignment
+12: lcd: Add support for flushing LCD fb from dcache after update
+ arm: + lubbock
+13: tegra: Align LCD frame buffer to section boundary
+14: tegra: Support control of cache settings for LCD
+15: tegra: fdt: Add LCD definitions for Seaboard
+16: lcd: Add CONFIG_CONSOLE_SCROLL_LINES option to speed console
+17: tegra: Enable display/lcd support on Seaboard
+18: wip
+
+This shows which commits have succeeded and which have failed. In this case
+the build is still in progress so many boards are not built yet (use -u to
+see which ones). But still we can see a few failures. The galaxy5200_LOWBOOT
+never builds correctly. This could be a problem with our toolchain, or it
+could be a bug in the upstream. The good news is that we probably don't need
+to blame our commits. The bad news is it isn't tested on that board.
+
+Commit 12 broke lubbock. That's what the '+ lubbock' means. The failure
+is never fixed by a later commit, or you would see lubbock again, in green,
+without the +.
+
+To see the actual error:
+
+$ ./tools/buildman/buildman -b <branch> -se lubbock
+...
+12: lcd: Add support for flushing LCD fb from dcache after update
+ arm: + lubbock
++common/libcommon.o: In function `lcd_sync':

+17: tegra: Enable display/lcd support on Seaboard
+18: wip
+
+So the problem is in lcd.c, due to missing cache operations. This information
+should be enough to work out what that commit is doing to break these
+boards. (In this case pxa did not have cache operations defined).
+
+If you see error lines marked with - that means that the errors were fixed
+by that commit. Sometimes commits can be in the wrong order, so that a
+breakage is introduced for a few commits and fixed by later commits. This
+shows up clearly with buildman. You can then reorder the commits and try
+again.
+
+At commit 16, the error moves - you can see that the old error at line 120
+is fixed, but there is a new one at line 126. This is probably only because
+we added some code and moved the broken line futher down the file.
+
+If many boards have the same error, then -e will display the error only
+once. This makes the output as concise as possible.
+
+The full build output in this case is available in:
+
+../lcd9b/12_of_18_gd92aff7_lcd--Add-support-for/lubbock/
+
+ done: Indicates the build was done, and holds the return code from make.
+ This is 0 for a good build, typically 2 for a failure.
+
+ err: Output from stderr, if any. Errors and warnings appear here.
+
+ log: Output from stdout. Normally there isn't any since buildman runs
+ in silent mode for now.
+
+ toolchain: Shows information about the toolchain used for the build.
+
+ sizes: Shows image size information.
+
+It is possible to get the build output there also. Use the -k option for

+
+Checking Image Sizes
+====================
+
+A key requirement for U-Boot is that you keep code/data size to a minimum.
+Where a new feature increases this noticeably it should normally be put
+behind a CONFIG flag so that boards can leave it off and keep the image
+size more or less the same with each new release.
+
+To check the impact of your commits on image size, use -S. For example:
+
+$ ./tools/buildman/buildman -b us-x86 -sS
+Summary of 10 commits for 1066 boards (4 threads, 1 job per thread)
+01: MAKEALL: add support for per architecture toolchains
+02: x86: Add function to get top of usable ram
+ x86: (for 1/3 boards) text -272.0 rodata +41.0
+03: x86: Add basic cache operations
+04: x86: Permit bootstage and timer data to be used prior to relocation
+ x86: (for 1/3 boards) data +16.0
+05: x86: Add an __end symbol to signal the end of the U-Boot binary
+ x86: (for 1/3 boards) text +76.0
+06: x86: Rearrange the output input to remove BSS
+ x86: (for 1/3 boards) bss -2140.0
+07: x86: Support relocation of FDT on start-up
+ x86: + coreboot-x86
+08: x86: Add error checking to x86 relocation code
+09: x86: Adjust link device tree include file
+10: x86: Enable CONFIG_OF_CONTROL on coreboot
+
+
+You can see that image size only changed on x86, which is good because this
+series is not supposed to change any other board. From commit 7 onwards the
+build fails so we don't get code size numbers. The numbers are fractional
+because they are an average of all boards for that architecture. The
+intention is to allow you to quickly find image size problems introduced by
+your commits.
+
+Note that the 'text' region and 'rodata' are split out. You should add the
+two together to get the total read-only size (reported as the first column
+in the output from binutil's 'size' utility).
+
+A useful option is --step which lets you skip some commits. For example
+--step 2 will show the image sizes for only every 2nd commit (so it will
+compare the image sizes of the 1st, 3rd, 5th... commits). You can also use
+--step 0 which will compare only the first and last commits. This is useful
+for an overview of how your entire series affects code size.
+
+You can also use -d to see a detailed size breakdown for each board. This
+list is sorted in order from largest growth to largest reduction.
+
+It is possible to go a little further with the -B option (--bloat). This
+shows where U-Boot has bloted, breaking the size change down to the function
+level. Example output is below:
+
+$ ./tools/buildman/buildman -b us-mem4 -sSdB

+
+
+This shows that commit 19 has increased text size for arm (although only one
+board was built) and by 96 bytes for powerpc. This increase was offset in both
+cases by reductions in rodata and data/bss.
+
+Shown below the summary lines is the sizes for each board. Below each board
+is the sizes for each function. This information starts with:
+
+ add - number of functions added / removed
+ grow - number of functions which grew / shrunk
+ bytes - number of bytes of code added to / removed from all functions,
+ plus the total byte change in brackets
+
+The change seems to be that hash_command() has increased by more than the
+do_mem_crc() function has decreased. The function sizes typically add up to
+roughly the text area size, but note that every read-only section except
+rodata is included in 'text', so the function total does not exactly
+correspond.
+
+It is common when refactoring code for the rodata to decrease as the text size
+increases, and vice versa.
+
+
+Other options
+=============
+
+Buildman has various other command line options. Try --help to see them.
+
+
+TODO
+====
+
+This has mostly be written in my spare time as a response to my difficulties
+in testing large series of patches. Apart from tidying up there is quite a
+bit of scope for improvement. Things like better error diffs, easier access
+to log files, error display while building. Also it would be nice it buildman
+could 'hunt' for problems, perhaps by building a few boards for each arch,
+or checking commits for changed files and building only boards which use
+those files.
+
+
+Credits
+=======
+
+Thanks to Grant Grundler <grundler@chromium.org> for his ideas for improving
+the build speed by building all commits for a board instead of the other
+way around.

+Theory of Operation
+
+Please see README for user documentation, and you should be familiar with
+that before trying to make sense of this.
+
+Buildman works by keeping the machine as busy as possible, building different
+commits for different boards on multiple CPUs at once.
+
+The source repo (self.git_dir) contains all the commits to be built. Each
+thread works on a single board at a time. It checks out the first commit,
+configures it for that board, then builds it. Then it checks out the next
+commit and builds it (typically without re-configuring). When it runs out
+of commits, it gets another job from the builder and starts again with that
+board.
+
+Clearly the builder threads could work either way - they could check out a
+commit and then built it for all boards. Using separate directories for each
+commit/board pair they could leave their build product around afterwards
+also.
+
+The intent behind building a single board for multiple commits, is to make
+use of incremental builds. Since each commit is built incrementally from
+the previous one, builds are faster. Reconfiguring for a different board
+removes all intermediate object files.
+
+Many threads can be working at once, but each has its own working directory.
+When a thread finishes a build, it puts the output files into a result
+directory.
+
+The base directory used by buildman is normally '../<branch>', i.e.
+a directory higher than the source repository and named after the branch
+being built.
+
+Within the base directory, we have one subdirectory for each commit. Within
+that is one subdirectory for each board. Within that is the build output for
+that commit/board combination.
+
+Buildman also create working directories for each thread, in a .bm-work/
+subdirectory in the base dir.
+
+As an example, say we are building branch 'us-net' for boards 'sandbox' and
+'seaboard', and say that us-net has two commits. We will have directories
+like this:
+
+us-net/ base directory
+ 01_of_02_g4ed4ebc_net--Add-tftp-speed-/
+ sandbox/
+ u-boot.bin
+ seaboard/
+ u-boot.bin
+ 02_of_02_g4ed4ebc_net--Check-tftp-comp/
+ sandbox/
+ u-boot.bin
+ seaboard/
+ u-boot.bin
