+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
