Wed Jan 31 22:54:29 CET 2007
Add support for the MPC8349E-mITX-GP, a stripped-down version of the
MPC8349E-mITX. Bonus features include support for low-boot (BMS bit in
HRCW is 0) for the ITX and a README for the ITX and the ITX-GP.

+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
+
+4. Definitions
+
+4.1 Explanation of NEW definitions in:
+
+ include/configs/MPC8349ITX.h
+
+ CONFIG_MPC83XX MPC83xx family
+ CONFIG_MPC8349 MPC8349 specific
+ CONFIG_MPC8349ITX MPC8349E-mITX
+ CONFIG_MPC8349ITXGP MPC8349E-mITX-GP
+
+5. Compilation
+
+ Assuming you're using BASH shell:
+
+ export CROSS_COMPILE=your-cross-compile-prefix
+ cd u-boot
+ make distclean
+
+ make MPC8349ITX_config
+ or:
+ make MPC8349ITXGP_config
+ or:
+ make MPC8349ITX_LOWBOOT_config
+
+ make
+
+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
+
+7. Notes
+ 1) The console baudrate for MPC8349EITX is 115200bps.
