-Summary:
-========
-
-This file contains information about the cmi board configuration.
-Please see cmi_mpc5xx_config for further details. The cmi board is
-a customer specific board but should work with small modifications
-on every board which has a MPC5xx and either a 28F128J3A,
-28F320J3A or 28F640J3A Intel flash mounted.
-
-Board Discription:
-==================
-
-* Motorola MPC555
-* RS232 connection
-* Intel flash 28F640J3A
-* Micron SRAM 1M
-* Altera PLD
-
-Bootstrap:
-==========
-
-In contrast to the usual boot sequence used in U-Boot, on the
-cmi board we don't boot from the external flash directly.
-Because of we use a 16-bit flash and don't sample a RCW
-from the data bus to set the startup buswidth to 16-bit.
-Unfortunatly the default width, sampled from the default RCW
-is 32-bit. For this reason we burn the proper RCW into the
-internal flash shadow location and boot after power-on or
-reset from the internal flash and then branch to 0x02000100
-where the U-Boot reset vector handler is located.
-
-Memory Map:
-===========
-
-Memory Map after relocation:
-
- 0x0000 0000 CONFIG_SYS_SDRAM_BASE
- :
- 0x000F 9FFF
- :
- :
- 0x0100 0000 CONFIG_SYS_IMMR (Internal memory map base adress)
- :
- 0x0130 7FFF
- :
- :
- 0x0200 0000 CONFIG_SYS_FLASH_BASE
- :
- 0x027C FFFF
- :
- :
- 0x0300 0000 PLD_BASE
-
-Flash Partition:
-
- 0x0200 0000 Block 0 and 1 contain U-Boot except
- : environment
- :
- 0x0201 FFFF
- 0x0202 0000 Block 2 contains environment (.ppcenv)
- :
- 0x0202 FFFF
-
-See README file for futher information about U-Boot relocation
-and partitioning.
-
-Tested Features:
-================
-
-* U-Boot commands: go, loads, loadb, all memory features, printenv,
- setenv, saveenv, protect, erase, fli, bdi, mtest, reset, version,
- coninfo, help (see configuration file for available commands)
-
-* Blinking led to indicate boot process
