+ mpc83xx: Fix the incorrect dcbz operation
+
+ The 834x rev1.x silicon has one CPU5 errata.
+
+ The issue is when the data cache locked with
+ HID0[DLOCK], the dcbz instruction looks like no-op inst.
+
+ The right behavior of the data cache is when the data cache
+ Locked with HID0[DLOCK], the dcbz instruction allocates
+ new tags in cache.
+
+ The 834x rev3.0 and later and 8360 have not this bug inside.
+
+ So, when 834x rev3.0/8360 are working with ECC, the dcbz
+ instruction will corrupt the stack in cache, the processor will
+ checkstop reset.
+
+ However, the 834x rev1.x can work with ECC with these code,
+ because the sillicon has this cache bug. The dcbz will not
+ corrupt the stack in cache.
+ Really, it is the fault code running on fault sillicon.
+
+ This patch fix the incorrect dcbz operation. Instead of
+ CPU FP writing to initialise the ECC.
+
+ CHANGELOG:
+ * Fix the incorrect dcbz operation instead of CPU FP
+ writing to initialise the ECC memory. Otherwise, it
+ will corrupt the stack in cache, The processor will checkstop

+ Overview:
+
+ 1. Include new 'i2c' command (based on USB implementation) using
+ CONFIG_I2C_CMD_TREE.
+
+ 2. Allow multiple buses by defining CONFIG_I2C_MULTI_BUS. Note that
+ the commands to change bus number and speed are only available under the
+ new 'i2c' command mentioned in the first bullet.
+
+ 3. The option CFG_I2C_NOPROBES has been expanded to work in multi-bus
+ systems. When CONFIG_I2C_MULTI_BUS is used, this option takes the form
+ of an array of bus-device pairs. Otherwise, it is an array of uchar.
+
+ CHANGELOG:
+ Added new 'i2c' master command for all I2C interaction. This is
+ conditionally compiled with CONFIG_I2C_CMD_TREE. New commands added for
+ setting I2C bus speed as well as changing the active bus if the board
+ has more than one (conditionally compiled with
+ CONFIG_I2C_MULTI_BUS). Updated NOPROBE logic to handle multiple buses.
+ Updated README.

+
+ NAND Flash verify across block boundaries
+
+ This patch addresses a problem when CONFIG_MTD_NAND_VERIFY_WRITE is
+ defined
+ and the write crosses a block boundary. The pointer to the verification
+ buffer (bufstart) is not being updated to reflect the starting of the
+ new
+ block so the verification of the second block fails.
+
+ CHANGELOG:
+
+ * Fix NAND FLASH page verification across block boundaries

clock chips. See common/cmd_i2c.c for a description of the
command line interface.
- CONFIG_HARD_I2C selects the CPM hardware driver for I2C.
+ CONFIG_I2C_CMD_TREE is a recommended option that places
+ all I2C commands under a single 'i2c' root command. The
+ older 'imm', 'imd', 'iprobe' etc. commands are considered
+ deprecated and may disappear in the future.
+
+ CONFIG_HARD_I2C selects a hardware I2C controller.
CONFIG_SOFT_I2C configures u-boot to use a software (aka
bit-banging) driver instead of CPM or similar hardware
in u-boot bd_info structure based on u-boot environment
variable "i2cfast". (see also i2cfast)
+ CONFIG_I2C_MULTI_BUS
+
+ This option allows the use of multiple I2C buses, each of which
+ must have a controller. At any point in time, only one bus is
+ active. To switch to a different bus, use the 'i2c dev' command.
+ Note that bus numbering is zero-based.
+
+ CFG_I2C_NOPROBES
+
+ This option specifies a list of I2C devices that will be skipped
+ when the 'i2c probe' command is issued (or 'iprobe' using the legacy
+ command). If CONFIG_I2C_MULTI_BUS is set, specify a list of bus-device
+ pairs. Otherwise, specify a 1D array of device addresses
+
+ e.g.
+ #undef CONFIG_I2C_MULTI_BUS
+ #define CFG_I2C_NOPROBES {0x50,0x68}
+
+ will skip addresses 0x50 and 0x68 on a board with one I2C bus
+
+ #define CONFIG_I2C_MULTI_BUS
+ #define CFG_I2C_MULTI_NOPROBES {{0,0x50},{0,0x68},{1,0x54}}
+
+ will skip addresses 0x50 and 0x68 on bus 0 and address 0x54 on bus 1
+
+ CFG_SPD_BUS_NUM
+
+ If defined, then this indicates the I2C bus number for DDR SPD.
+ If not defined, then U-Boot assumes that SPD is on I2C bus 0.
+
+ CONFIG_FSL_I2C
+
+ Define this option if you want to use Freescale's I2C driver in
+ drivers/fsl_i2c.c.
+
+
- SPI Support: CONFIG_SPI
Enables SPI driver (so far only tested with
CFG_POCMR2_MASK_ATTRIB: (MPC826x only)
Overrides the default PCI memory map in cpu/mpc8260/pci.c if set.
+- CONFIG_SPD_EEPROM
+ Get DDR timing information from an I2C EEPROM. Common with pluggable
+ memory modules such as SODIMMs
+ SPD_EEPROM_ADDRESS
+ I2C address of the SPD EEPROM
+
+- CFG_SPD_BUS_NUM
+ If SPD EEPROM is on an I2C bus other than the first one, specify here.
+ Note that the value must resolve to something your driver can deal with.
+
+- CFG_83XX_DDR_USES_CS0
+ Only for 83xx systems. If specified, then DDR should be configured
+ using CS0 and CS1 instead of CS2 and CS3.
+
+- CFG_83XX_DDR_USES_CS0
+ Only for 83xx systems. If specified, then DDR should be configured
+ using CS0 and CS1 instead of CS2 and CS3.

+* share four address windows. Each region can be individually configured
+* by this function by associating it to a target interface and setting
+* base and size values.
+*
+* NOTE!!!
+* The size must be in 64Kbyte granularity.
+* The base address must be aligned to the size.
+* The size must be a series of 1s followed by a series of zeros
+*
+* OUTPUT:
+* None.
+*
+* RETURN:
+* True for success, false otherwise.

+ * Marvell's Gigabit Ethernet controller low level driver
+ *
+ * DESCRIPTION:
+ * This file introduce low level API to Marvell's Gigabit Ethernet
+ * controller. This Gigabit Ethernet Controller driver API controls
+ * 1) Operations (i.e. port init, start, reset etc').
+ * 2) Data flow (i.e. port send, receive etc').
+ * Each Gigabit Ethernet port is controlled via ETH_PORT_INFO
+ * struct.
+ * This struct includes user configuration information as well as
+ * driver internal data needed for its operations.
+ *
+ * Supported Features:
+ * - This low level driver is OS independent. Allocating memory for
+ * the descriptor rings and buffers are not within the scope of
+ * this driver.
+ * - The user is free from Rx/Tx queue managing.
+ * - This low level driver introduce functionality API that enable
+ * the to operate Marvell's Gigabit Ethernet Controller in a
+ * convenient way.
+ * - Simple Gigabit Ethernet port operation API.
+ * - Simple Gigabit Ethernet port data flow API.
+ * - Data flow and operation API support per queue functionality.
+ * - Support cached descriptors for better performance.
+ * - Enable access to all four DRAM banks and internal SRAM memory
+ * spaces.
+ * - PHY access and control API.
+ * - Port control register configuration API.
+ * - Full control over Unicast and Multicast MAC configurations.
+ *
+ * Operation flow:
+ *
+ * Initialization phase
+ * This phase complete the initialization of the ETH_PORT_INFO
+ * struct.
+ * User information regarding port configuration has to be set
+ * prior to calling the port initialization routine. For example,
+ * the user has to assign the port_phy_addr field which is board
+ * depended parameter.
+ * In this phase any port Tx/Rx activity is halted, MIB counters
+ * are cleared, PHY address is set according to user parameter and
+ * access to DRAM and internal SRAM memory spaces.
+ *
+ * Driver ring initialization
+ * Allocating memory for the descriptor rings and buffers is not
+ * within the scope of this driver. Thus, the user is required to
+ * allocate memory for the descriptors ring and buffers. Those
+ * memory parameters are used by the Rx and Tx ring initialization
+ * routines in order to curve the descriptor linked list in a form
+ * of a ring.
+ * Note: Pay special attention to alignment issues when using
+ * cached descriptors/buffers. In this phase the driver store
+ * information in the ETH_PORT_INFO struct regarding each queue
+ * ring.
+ *
+ * Driver start
+ * This phase prepares the Ethernet port for Rx and Tx activity.
+ * It uses the information stored in the ETH_PORT_INFO struct to
+ * initialize the various port registers.
+ *
+ * Data flow:
+ * All packet references to/from the driver are done using PKT_INFO
+ * struct.
+ * This struct is a unified struct used with Rx and Tx operations.
+ * This way the user is not required to be familiar with neither
+ * Tx nor Rx descriptors structures.
+ * The driver's descriptors rings are management by indexes.
+ * Those indexes controls the ring resources and used to indicate
+ * a SW resource error:
+ * 'current'
+ * This index points to the current available resource for use. For
+ * example in Rx process this index will point to the descriptor
+ * that will be passed to the user upon calling the receive routine.
+ * In Tx process, this index will point to the descriptor
+ * that will be assigned with the user packet info and transmitted.
+ * 'used'
+ * This index points to the descriptor that need to restore its
+ * resources. For example in Rx process, using the Rx buffer return
+ * API will attach the buffer returned in packet info to the
+ * descriptor pointed by 'used'. In Tx process, using the Tx
+ * descriptor return will merely return the user packet info with
+ * the command status of the transmitted buffer pointed by the
+ * 'used' index. Nevertheless, it is essential to use this routine
+ * to update the 'used' index.
+ * 'first'
+ * This index supports Tx Scatter-Gather. It points to the first
+ * descriptor of a packet assembled of multiple buffers. For example
+ * when in middle of Such packet we have a Tx resource error the
+ * 'curr' index get the value of 'first' to indicate that the ring
+ * returned to its state before trying to transmit this packet.
+ *
+ * Receive operation:
+ * The eth_port_receive API set the packet information struct,
+ * passed by the caller, with received information from the
+ * 'current' SDMA descriptor.
+ * It is the user responsibility to return this resource back
+ * to the Rx descriptor ring to enable the reuse of this source.
+ * Return Rx resource is done using the eth_rx_return_buff API.
+ *
+ * Transmit operation:
+ * The eth_port_send API supports Scatter-Gather which enables to
+ * send a packet spanned over multiple buffers. This means that
+ * for each packet info structure given by the user and put into
+ * the Tx descriptors ring, will be transmitted only if the 'LAST'
+ * bit will be set in the packet info command status field. This
+ * API also consider restriction regarding buffer alignments and
+ * sizes.
+ * The user must return a Tx resource after ensuring the buffer
+ * has been transmitted to enable the Tx ring indexes to update.
+ *
+ * BOARD LAYOUT
+ * This device is on-board. No jumper diagram is necessary.
+ *
+ * EXTERNAL INTERFACE
+ *
+ * Prior to calling the initialization routine eth_port_init() the user
+ * must set the following fields under ETH_PORT_INFO struct:
+ * port_num User Ethernet port number.
+ * port_phy_addr User PHY address of Ethernet port.
+ * port_mac_addr[6] User defined port MAC address.
+ * port_config User port configuration value.
+ * port_config_extend User port config extend value.
+ * port_sdma_config User port SDMA config value.
+ * port_serial_control User port serial control value.
+ * *port_virt_to_phys () User function to cast virtual addr to CPU bus addr.
+ * *port_private User scratch pad for user specific data structures.
+ *
+ * This driver introduce a set of default values:
+ * PORT_CONFIG_VALUE Default port configuration value
+ * PORT_CONFIG_EXTEND_VALUE Default port extend configuration value
+ * PORT_SDMA_CONFIG_VALUE Default sdma control value
+ * PORT_SERIAL_CONTROL_VALUE Default port serial control value
+ *
+ * This driver data flow is done using the PKT_INFO struct which is
+ * a unified struct for Rx and Tx operations:
+ * byte_cnt Tx/Rx descriptor buffer byte count.
+ * l4i_chk CPU provided TCP Checksum. For Tx operation only.
+ * cmd_sts Tx/Rx descriptor command status.
+ * buf_ptr Tx/Rx descriptor buffer pointer.
+ * return_info Tx/Rx user resource return information.
+ *
+ *
+ * EXTERNAL SUPPORT REQUIREMENTS
+ *
+ * This driver requires the following external support:
+ *
+ * D_CACHE_FLUSH_LINE (address, address offset)
+ *
+ * This macro applies assembly code to flush and invalidate cache
+ * line.
+ * address - address base.
+ * address offset - address offset
+ *
+ *
+ * CPU_PIPE_FLUSH
+ *
+ * This macro applies assembly code to flush the CPU pipeline.

+Freescale MPC8360EMDS Board
+-----------------------------------------
+1. Board Switches and Jumpers
+1.0 There are four Dual-In-Line Packages(DIP) Switches on MPC8360EMDS board
+ For some reason, the HW designers describe the switch settings
+ in terms of 0 and 1, and then map that to physical switches where
+ the label "On" refers to logic 0 and "Off" is logic 1.
+
+ Switch bits are numbered 1 through, like, 4 6 8 or 10, but the
+ bits may contribute to signals that are numbered based at 0,
+ and some of those signals may be high-bit-number-0 too. Heed
+ well the names and labels and do not get confused.
+
+ "Off" == 1
+ "On" == 0
+
+ SW18 is switch 18 as silk-screened onto the board.
+ SW4[8] is the bit labled 8 on Switch 4.
+ SW2[1:6] refers to bits labeled 1 through 6 in order on switch 2.
+ SW3[7:1] refers to bits labeled 7 through 1 in order on switch 3.
+ SW3[1:8]= 0000_0001 refers to bits labeled 1 through 6 is set as "On"
+ and bits labeled 8 is set as "Off".
+
+1.1 For the MPC8360E PB PROTO Board
+
+ First, make sure the board default setting is consistent with the
+ document shipped with your board. Then apply the following setting:
+ SW3[1-8]= 0000_0100 (HRCW setting value is performed on local bus)
+ SW4[1-8]= 0011_0000 (Flash boot on local bus)
+ SW9[1-8]= 0110_0110 (PCI Mode enabled. HRCW is read from FLASH)
+ SW10[1-8]= 0000_1000 (core PLL setting)
+ SW11[1-8]= 0000_0100 (SW11 is on the another side of the board)
+ JP6 1-2
+ on board Oscillator: 66M
+
+
+2. Memory Map
+
+2.1. The memory map should look pretty much like this:
+
+ 0x0000_0000 0x7fff_ffff DDR 2G
+ 0x8000_0000 0x8fff_ffff PCI MEM prefetch 256M
+ 0x9000_0000 0x9fff_ffff PCI MEM non-prefetch 256M
+ 0xc000_0000 0xdfff_ffff Empty 512M
+ 0xe000_0000 0xe01f_ffff Int Mem Reg Space 2M
+ 0xe020_0000 0xe02f_ffff Empty 1M
+ 0xe030_0000 0xe03f_ffff PCI IO 1M
+ 0xe040_0000 0xefff_ffff Empty 252M
+ 0xf000_0000 0xf3ff_ffff Local Bus SDRAM 64M
+ 0xf400_0000 0xf7ff_ffff Empty 64M
+ 0xf800_0000 0xf800_7fff BCSR on CS1 32K
+ 0xf800_8000 0xf800_ffff PIB CS4 32K
+ 0xf801_0000 0xf801_7fff PIB CS5 32K
+ 0xfe00_0000 0xfeff_ffff FLASH on CS0 16M
+
+
+3. Definitions
+
+3.1 Explanation of NEW definitions in:
+
+ include/configs/MPC8360EMDS.h
+
+ CONFIG_MPC83XX MPC83xx family for both MPC8349 and MPC8360
+ CONFIG_MPC8360 MPC8360 specific
+ CONFIG_MPC8360EMDS MPC8360EMDS board specific
+
+4. Compilation
+
+ Assuming you're using BASH shell:
+
+ export CROSS_COMPILE=your-cross-compile-prefix
+ cd u-boot
+ make distclean
+ make MPC8360EMDS_config
+ make
+
+ MPC8360 support PCI in host and slave mode.
+
+ To make u-boot support PCI host 66M :
+ 1) DIP SW support PCI mode as described in Section 1.1.
+ 2) Make MPC8360EMDS_HOST_66_config
+
+ To make u-boot support PCI host 33M :
+ 1) DIP SW setting is similar as Section 1.1, except for SW3[4] is 1
+ 2) Make MPC8360EMDS_HOST_33_config
+
+ To make u-boot support PCI slave 66M :
+ 1) DIP SW setting is similar as Section 1.1, except for SW9[3] is 1
+ 2) Make MPC8360EMDS_SLAVE_config
+
+
+5. Downloading and Flashing Images
+
+5.0 Download over serial line using Kermit:
+
+ loadb
+ [Drop to kermit:
+ ^\c
+ send <u-boot-bin-image>
+ c
+ ]
+
+
+ Or via tftp:
+
+ tftp 10000 u-boot.bin
+
+5.1 Reflash U-boot Image using U-boot
+
+ tftp 20000 u-boot.bin
+ protect off fef00000 fef3ffff
+ erase fef00000 fef3ffff
+
+ cp.b 20000 fef00000 xxxx
+
+ or
+
+ cp.b 20000 fef00000 3ffff
+
+
+You have to supply the correct byte count with 'xxxx' from the TFTP result log.
+Maybe 3ffff will work too, that corresponds to the erased sectors.
+
+
+6. Notes
+ 1) The console baudrate for MPC8360EMDS is 115200bps.
