+ [PATCH] Update AMCC Luan 440SP eval board support
+
+ The AMCC Luan now uses the common 440SP(e) DDR SPD code for DDR
+ inititializition. This includes DDR auto calibration and support
+ for different DIMM modules, instead of the fixed setup used in
+ the earlier version.
+
+ This patch also enables the cache in FLASH for the startup
+ phase of U-Boot (while running from FLASH). After relocating to
+ SDRAM the cache is disabled again. This will speed up the boot
+ process, especially the SDRAM setup, since there are some loops
+ for memory testing (auto calibration).

+
+ [PATCH] Fix AMCC 44x SPD SDRAM init code to support 2 DIMM's
+
+ This patch fixes a problem that occurs when 2 DIMM's are
+ used. This problem was first spotted and fixed by Gerald Jackson
+ <gerald.jackson@reaonixsecurity.com> but this patch fixes the
+ problem in a little more clever way.
+
+ This patch also adds the nice functionality to dynamically
+ create the TLB entries for the SDRAM (tlb.c). So we should
+ never run into such problems with wrong (too short) TLB
+ initialization again on these platforms.
+
+ As this feature is new to the "old" 44x SPD DDR driver, it
+ has to be enabled via the CONFIG_PROG_SDRAM_TLB define.

+ [PATCH] Speed optimization of AMCC Sequoia/Rainier DDR2 setup
+
+ As provided by the AMCC applications team, this patch optimizes the
+ DDR2 setup for 166MHz bus speed. The values provided are also save
+ to use on a "normal" 133MHz PLB bus system. Only the refresh counter
+ setup has to be adjusted as done in this patch.
+
+ For this the NAND booting version had to include the "speed.c" file
+ from the cpu/ppc4xx directory. With this addition the NAND SPL image
+ will just fit into the 4kbytes of program space. gcc version 4.x as
+ provided with ELDK 4.x is needed to generate this optimized code.

+
+ The patch solves the alignment problem of the local bus access windows to
+ render accessible the memory bank and PHY registers of UPC 1 (starting at
+ 0xf801 0000). What we actually did was to adjust the sizes of the bus
+ access windows so that the base address alignment requirement would be met.

+ mpc83xx: U-Boot support for Wind River SBC8349
+
+ I've redone the SBC8349 support to match git-current, which
+ incorporates all the MPC834x updates from Freescale since the 1.1.6
+ release, including the DDR changes.
+
+ I've kept all the SBC8349 files as parallel as possible to the
+ MPC8349EMDS ones for ease of maintenance and to allow for easy
+ inspection of what was changed to support this board. Hence the SBC8349
+ U-Boot has FDT support and everything else that the MPC8349EMDS has.
+
+ Fortunately the Freescale updates added support for boards using CS0,
+ but I had to change spd_sdram.c to allow for board specific settings for
+ the sdram_clk_cntl (it is/was hard coded to zero, and that remains the
+ default if the board doesn't specify a value.)
+
+ Hopefully this should be mergeable as-is and require no whitespace
+ cleanups or similar, but if something doesn't measure up then let me
+ know and I'll fix it.
+
+ Thanks,
+ Paul.

+
+ [PATCH] nand: Fix problem with oobsize calculation
+
+ Here the description from Brian Brelsford <Brian_Brelsford@dell.com>:
+
+ The Hynix part returns a 0x1d in the 4th ID byte. The Samsung part
+ returns a 0x15. In the code fragment below bits [1:0] determine the
+ page size, it is ANDed via "(extid & 0x3)" then shifted out. The
+ next field is also ANDed with 0x3. However this is a one bit field
+ as defined in the Hynix and Samsung parts in the 4th ID byte that
+ determins the oobsize, not a two bit field. It works on Samsung as
+ bits[3:2] are 01. However for the Hynix there is a 11 in these two
+ bits, so the oob size gets messed up.
+
+ I checked the correct linux code and the suggested fix from Brian is
+ also available in the linux nand mtd driver.

+ 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
+ reset.

+
+ Hello,

+ Attached is a patch implementing multiple I2C buses on the MPC834x CPU

+ Add support for multiple I2C buses
+
+ Hello,
+
+ Attached is a patch providing support for multiple I2C buses at the
+ command level. The second part of the patch includes an implementation
+ for the MPC834x CPU and MPC8349EMDS board.

+
+ 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.
+
+ regards,
+ Ben

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.
+
+ CFG_RTC_BUS_NUM
+
+ If defined, then this indicates the I2C bus number for the RTC.
+ If not defined, then U-Boot assumes that RTC is on I2C bus 0.
+
+ CFG_DTT_BUS_NUM
+
+ If defined, then this indicates the I2C bus number for the DTT.
+ If not defined, then U-Boot assumes that DTT 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.
+

+* 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 MPC832XEMDS Board
+-----------------------------------------
+1. Board Switches and Jumpers
+1.0 There are five Dual-In-Line Packages(DIP) Switches on MPC832XE SYS 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
+
+ SW3 is switch 18 as silk-screened onto the board.
+ SW4[8] is the bit labled 8 on Switch 4.
+ SW5[1:6] refers to bits labeled 1 through 6 in order on switch 5.
+ SW6[7:1] refers to bits labeled 7 through 1 in order on switch 6.
+ SW7[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 MPC832XEMDS 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_1000 (core PLL setting, core enable)
+ SW4[1-8]= 0001_0010 (Flash boot on local bus, system PLL setting)
+ SW5[1-8]= 0010_0110 (Boot from high end)
+ SW6[1-8]= 0011_0100 (Flash boot on 16 bit local bus)
+ SW7[1-8]= 1000_0011 (QE PLL setting)
+
+ ENET3/4 MII mode settings:
+ J1 1-2 (ETH3_TXER)
+ J2 2-3 (MII mode)
+ J3 2-3 (MII mode)
+ J4 2-3 (ADSL clockOscillator)
+ J5 1-2 (ETH4_TXER)
+ J6 2-3 (ClockOscillator)
+ JP1 removed (don't force PORESET)
+ JP2 mounted (ETH4/2 MII)
+ JP3 mounted (ETH3 MII)
+ JP4 mounted (HRCW from BCSR)
+
+ ENET3/4 RMII mode settings:
+ J1 1-2 (ETH3_TXER)
+ J2 1-2 (RMII mode)
+ J3 1-2 (RMII mode)
+ J4 2-3 (ADSL clockOscillator)
+ J5 1-2 (ETH4_TXER)
+ J6 2-3 (ClockOscillator)
+ JP1 removed (don't force PORESET)
+ JP2 removed (ETH4/2 RMII)
+ JP3 removed (ETH3 RMII)
+ JP4 removed (HRCW from FLASH)
+
+ 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
+ 0xf400_0000 0xf7ff_ffff Empty 64M
+ 0xf800_0000 0xf800_7fff BCSR on CS1 32K
+ 0xf800_8000 0xf800_ffff PIB CS2 32K
+ 0xf801_0000 0xf801_7fff PIB CS3 32K
+ 0xfe00_0000 0xfeff_ffff FLASH on CS0 16M

+
+ include/configs/MPC832XEPB.h
+
+ CONFIG_MPC83XX MPC83XX family for MPC8349, MPC8360 and MPC832X
+ CONFIG_MPC832X MPC832X specific
+ CONFIG_MPC832XEMDS MPC832XEMDS board specific
+
+4. Compilation
+
+ Assuming you're using BASH shell:
+
+ export CROSS_COMPILE=your-cross-compile-prefix
+ cd u-boot
+ make distclean
+ make MPC832XEMDS_config
+ make
+
+ MPC832X support PCI 33MHz and PCI 66MHz, to make u-boot support PCI:
+
+ 1)Make sure the DIP SW support PCI mode as described in Section 1.1.
+
+ 2)To Make U-Boot image support PCI 33MHz, use
+ Make MPC832XEMDS_HOST_33_config
+
+ 3)To Make U-Boot image support PCI 66MHz, use
+ Make MPC832XEMDS_HOST_66M_config
+
+5. Downloading and Flashing Images
+
+5.0 Download over network:
+
+ tftp 10000 u-boot.bin
+
+5.1 Reflash U-boot Image using U-boot
+
+ tftp 20000 u-boot.bin
+ protect off fe000000 fe0fffff
+ erase fe000000 fe0fffff
+ cp.b 20000 fe000000 xxxx
+
+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 MPC832XEMDS is 115200bps.

+Freescale MPC8349E-mITX and MPC8349E-mITX-GP Boards
+---------------------------------------------------
+
+1. Board Description
+
+ The MPC8349E-mITX and MPC8349E-mITX-GP are reference boards featuring
+ the Freescale MPC8349E processor in a Mini-ITX form factor.
+
+ The MPC8349E-mITX-GP is an MPC8349E-mITX with the following differences:
+
+ A) One 8MB on-board flash EEPROM chip, instead of two.
+ B) No SATA controller
+ C) No Compact Flash slot
+ D) No Mini-PCI slot
+ E) No Vitesse 7385 5-port Ethernet switch
+ F) No 4-port USB Type-A interface
+
+2. Board Switches and Jumpers
+
+2.0 Descriptions for all of the board jumpers can be found in the User
+ Guide. Of particular interest to U-Boot developers is jumper J22:
+
+ Pos. Name Default Description
+ -----------------------------------------------------------------------
+ A LGPL0 ON (0) HRCW source, bit 0
+ B LGPL1 ON (0) HRCW source, bit 1
+ C LGPL3 ON (0) HRCW source, bit 2
+ D LGPL5 OFF (1) PCI_SYNC_OUT frequency
+ E BOOT1 ON (0) Flash EEPROM boot device
+ F PCI_M66EN ON (0) PCI 66MHz enable
+ G I2C-WP ON (0) I2C EEPROM write protection
+ H F_WP OFF (1) Flash EEPROM write protection
+
+ Jumper J22.E is only for the ITX, and it decides the configuration
+ of the flash chips. If J22.E is ON (i.e. jumpered), then flash chip
+ U4 is located at address FE000000 and flash chip U7 is at FE800000.
+ If J22.E is OFF, then U7 is at FE000000 and U4 is at FE800000.
+
+ For U-Boot development, J22.E can be used to switch back-and-forth
+ between two U-Boot images.
+
+3. Memory Map
+
+3.1. The memory map should look pretty much like this:
+
+ 0x0000_0000 - 0x0FFF_FFFF DDR SDRAM (256 MB)
+ 0x8000_0000 - 0x9FFF_FFFF PCI1 memory space (512 MB)
+ 0xA000_0000 - 0xBFFF_FFFF PCI2 memory space (512 MB)
+ 0xE000_0000 - 0xEFFF_FFFF IMMR (1 MB)
+ 0xE200_0000 - 0xE2FF_FFFF PCI1 I/O space (16 MB)
+ 0xE300_0000 - 0xE3FF_FFFF PCI2 I/O space (16 MB)
+ 0xF000_0000 - 0xF000_FFFF Compact Flash (ITX only)
+ 0xF001_0000 - 0xF001_FFFF Local bus expansion slot
+ 0xF800_0000 - 0xF801_FFFF Vitesse 7385 Parallel Interface (ITX only)
+ 0xFE00_0000 - 0xFE7F_FFFF First 8MB bank of Flash memory
+ 0xFE80_0000 - 0xFEFF_FFFF Second 8MB bank of Flash memory (ITX only)
+
+3.2 Flash EEPROM layout.
+
+ On the ITX, jumper J22.E is used to determine which flash chips are
+ at which address. When J22.E is switched, addresses from FE000000
+ to FE7FFFFF are swapped with addresses from FE800000 to FEFFFFFF.
+
+ On the ITX, at the normal boot address (aka HIGHBOOT):
+
+ FE00_0000 HRCW
+ FE70_0000 Alternative U-Boot image
+ FE80_0000 Alternative HRCW
+ FEF0_0000 U-Boot image
+ FEFF_FFFF End of flash
+
+ On the ITX, at the low boot address (LOWBOOT)
+
+ FE00_0000 HRCW and U-Boot image
+ FE04_0000 U-Boot environment variables
+ FE80_0000 Alternative HRCW and U-Boot image
+ FEFF_FFFF End of flash
+
+ On the ITX-GP, the only option is LOWBOOT and there is only one chip
+
+ FE00_0000 HRCW and U-Boot image
+ FE04_0000 U-Boot environment variables
+ F7FF_FFFF End of flash

+6. Downloading and Flashing Images
+
+6.1 Download via tftp:
+
+ tftp $loadaddr <uboot>
+
+ where "<uboot>" is the path and filename, on the TFTP server, of
+ the U-Boot image.
+
+6.1 Reflash U-Boot Image using U-Boot
+
+ setenv uboot <uboot>
+ run tftpflash
+
+ where "<uboot>" is the path and filename, on the TFTP server, of
+ the U-Boot image.
+
+6.2 Using the HRCW to switch between two different U-Boot images on the ITX
+
+ Because the ITX has 16MB of flash, it is possible to keep two U-Boot
+ images in flash, and use the HRCW to specify which one is to be used
+ when the board boots. This trick is especially effective with a
+ hardware debugger that can override the HRCW, such as the BDI-2000.
+
+ When the BMS bit in the HRCW is 0, the ITX will boot the U-Boot image
+ at address FE000000. When the BMS bit is 1, the ITX will boot the
+ image at address FEF00000.
+
+ Therefore, just put a U-Boot image at both FE000000 and FEF00000 and
+ change the BMS bit whenever you want to boot the other image.
+
+ Step-by-step instructions:
+
+ 1) Build an ITX image to be loaded at FEF00000
+
+ make distclean
+ make MPC8349ITX_config
+ make
+
+ 2) Take the u-boot.bin image and flash it at FEF00000.
+
+ tftp $loadaddr u-boot.bin
+ protect off all
+ erase FEF00000 +$filesize
+ cp.b $loadaddr FEF00000 $filesize
+
+ 3) Build an ITX image to be loaded at FE000000
+
+ make distclean
+ make MPC8349ITX_LOWBOOT_config
+ make
+
+ 4) Take the u-boot.bin image and flash it at FE000000.
+
+ tftp $loadaddr u-boot.bin
+ protect off FE000000 +$filesize
+ erase FE000000 +$filesize
+ cp.b $loadaddr FE000000 $filesize
+
+ The HRCW in flash is currently set to boot the image at FE000000.
+
+ If you have a hardware debugger, configure it to set the HRCW to
+ B460A000 04040000 if you want to boot the image at FEF00000, or set
+ it to B060A000 04040000 if you want to boot the image at FE000000.
+
+ To change the HRCW in flash to boot the image at FEF00000, use these
+ U-Boot commands:
+
+ cp.b FE000000 1000 10000 ; copy 1st flash sector to 1000
+ mw.b 1020 b4 8 ; modify BMS bit
+ protect off FE000000 +10000
+ erase FE000000 +10000
+ cp.b 1000 FE000000 10000

+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

+ 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.
+
+

+ U-Boot for Wind River SBC834x Boards
+ ====================================
+
+
+The Wind River SBC834x board is a 6U form factor (not CPCI) reference
+design that uses the MPC8347E or MPC8349E processor. U-Boot support
+for this board is heavily based on the existing U-Boot support for
+Freescale MPC8349 reference boards.
+
+Support has been primarily tested on the SBC8349 version of the board,
+although earlier versions were also tested on the SBC8347. The primary
+difference in the two is the level of PCI functionality.
+
+ http://www.windriver.com/products/OCD/SBC8347E_49E/
+
+
+Flash Details:
+==============
+
+The flash type is intel 28F640Jx (4096x16) [one device]. Base address
+is 0xFF80_0000 which is also where the Hardware Reset Configuration
+Word (HRCW) is stored. Caution should be used to not overwrite the
+HRCW, or "CF RCW" with a Wind River ICE will be required to restore
+the HRCW and allow the board to enter background mode for further
+steps in the flash process.
+
+
+Restoring a corrupted or missing flash image:
+=============================================
+
+Details for storing U-boot to flash using a Wind River ICE can be found
+on page 19 of the board manual (request ERG-00328-001). The following
+is a summary of that information:
+
+ - Connect ICE and establish connection to it from WorkBench/OCD.
+ - Ensure you have background mode (BKM) in the OCD terminal window.
+ - Select the appropriate flash type (listed above)
+ - Prepare a u-boot image by using the Wind River Convert utility;
+ by using "Convert and Add file" on the ELF file from your build.
+ Convert from FFF0_0000 to FFFF_FFFF (or to FFF3_FFFF if you are
+ trying to preserve your old environment settings).
+ - Set the start address of the erase/flash process to FFF0_0000
+ - Set the target RAM required to 64kB.
+ - Select sectors for erasing (see note on enviroment below)
+ - Select Erase and Reprogram.
+
+Note that some versions of the register files used with Workbench
+would zero some TSEC registers, which inhibits ethernet operation
+by u-boot when this register file is played to the target. Using
+"INN" in the OCD terminal window instead of "IN" before the "GO"
+will not play the register file, and allow u-boot to use the TSEC
+interface while executed from the ICE "GO" command.
+
+Alternatively, you can locate the register file which will be named
+WRS_SBC8349_PCT00328001.reg or similar) and "REM" out all the lines
+beginning with "SCGA TSEC1" and "SCGA TSEC2". This allows you to
+use all the remaining register file content.
+
+If you wish to preserve your prior U-Boot environment settings,
+then convert (and erase to) 0xFFF3FFFF instead of 0xFFFFFFFF.
+The size for converting (and erasing) must be at least as large
+as u-boot.bin.
+
+
+Updating U-Boot with U-Boot:
+============================
+
+This procedure is very similar to other boards that have u-boot installed.
+Assuming that the network has been configured, and that the new u-boot.bin
+has been copied to the TFTP server, the commands are:
+
+ tftp 200000 u-boot.bin
+ protect off all
+ erase fff00000 fff3ffff
+ cp.b 200000 fff00000 3ffff
+ protect on all
+
+
+PCI:
+====
+
+This board and U-Boot have been tested with PCI built in, on a SBC8349
+and confirmed that the "pci" command showed the intel e1000 that was
+present in the PCI slot. Note that if a 33MHz 32bit card is inserted
+in the slot, then the whole board will clock down to a 33MHz base
+clock instead of the default 66MHz. This will change the baud clocks
+and mess up your serial console output. If you want to use a 33MHz PCI
+card, then you should build a U-Boot with #undef PCI_66M in the
+include/configs/sbc8349.h and store this to flash prior to powering down
+the board and inserting the 33MHz PCI card.
+
+By default PCI support is disabled to better support very early
+revision MPC834x chips with possible PCI issues. Also PCI support is
+untested on the sbc8347 variants at this point in time.
