+Cogent Modular Architecture configuration
+-----------------------------------------
+
+As the name suggests, the Cogent platform is a modular system where
+you have a motherboard into which plugs a cpu module and one or more
+i/o modules. This provides very nice flexibility, but makes the
+configuration task somewhat harder.
+
+The possible Cogent motherboards are:
+
+Code Config Variable Description
+---- --------------- -----------
+
+CMA101 CONFIG_CMA101 32MB ram, 2 ser, 1 par, rtc, dipsw,
+ 2x16 lcd, eth(?)

+CMA150 CONFIG_CMA150 8MB ram, 1MB flash, 2 ser, 1 par, rtc,
+ ps/2 kbd/mse, 2x16 lcd
+
+The possible Cogent PowerPC CPU modules are:
+

+CMA286-60P CONFIG_CMA286_60P MPC860P CPU, 66MHz clock, 512K EPROM,
+ BDM, 16M RAM, 2 x ser (SMC1 + SMC2),

+ BDM
+CMA287-50 CONFIG_CMA287_50 MPC850 CPU, 33MHz clock, 512K EPROM,
+ BDM
+
+(there are a lot of other cpu modules with ARM, MIPS and M-CORE CPUs,
+but we'll worry about those later).
+
+The possible Cogent CMA I/O Modules are:
+
+Code Config Variable Description
+---- --------------- -----------
+
+CMA302 CONFIG_CMA302 up to 16M flash, ps/2 keyboard/mouse
+CMA352 CONFIG_CMA352 CMAbus <=> PCI
+
+Currently supported:
+
+ Motherboards: CMA102
+ CPU Modules: CMA286-60-OLD
+ I/O Modules: CMA302 I/O module
+
+To configure, perform the usual U-Boot configuration task of editing
+"include/config_cogent_mpc8xx.h" and reviewing all the options and
+settings in there. In particular, check the chip select values
+installed into the memory controller's various option and base
+registers - these are set by the defines CFG_CMA_CSn_{BASE,SIZE} and
+CFG_{B,O}Rn_PRELIM. Also be careful of the clock settings installed
+into the SCCR - via the define CFG_SCCR. Finally, decide whether you
+want the serial console on motherboard serial port A or on one of the
+8xx SMC ports, and set CONFIG_8xx_CONS_{SMC1,SMC2,NONE} accordingly
+(NONE means use Cogent motherboard serial port A).
+
+Then edit the file "cogent/config.mk". Firstly, set TEXT_BASE to be
+the base address of the EPROM for the CPU module. This should be the
+same as the value selected for CFG_MONITOR_BASE in
+"include/config_cogent_*.h" (in fact, I have made this automatic via
+the -DTEXT_BASE=... option in CPPFLAGS).
+
+Finally, set the values of the make variables $(CMA_MB) and $(CMA_IOMS).
+
+$(CMA_MB) is the name of the directory that contains support for your
+motherboard. At this stage, only "cma10x" exists, which supports the
+CMA101 and CMA102 motherboards - but only selected devices, namely
+serial, lcd and dipsw.
+
+$(CMA_IOMS) is a list of zero or more directories that contain
+support for the i/o modules you have installed. At this stage, only
+"cma302" exists, which supports the CMA302 flash i/o module - but
+only the flash part, not the ps/2 keyboard and mouse interfaces.
+
+There should be a make variable for each of the above directories,
+which is the directory name with "_O" appended. This make variable is
+a list of object files to compile from that directory and include in
+the library.
+
+ e.g. cma10x_O = serial.o ...
+
+That's it. Good Luck.

+ppcboot for a CU824 board
+---------------------------
+
+CU824 has two banks of flash 8MB each. In board's notation, bank 0 is
+the one at the address of 0xFF800000 and bank 1 is the one at the
+address of 0xFF000000. On power-up the processor jumps to the address
+of 0xFFF00100, the last megabyte of the bank 0 of flash. Thus,
+U-Boot is configured to reside in flash starting at the address of
+0xFFF00000. The environment space is not embedded in the U-Boot code
+and is located in flash separately from U-Boot, at the address of
+0xFF008000.

+
+To make a system for gth that actually works ;-)
+the variable TBASE needs to be set to 0,1 or 2
+depending on location where image is supposed to
+be started from.
+E.g. make TBASE=1
+
+0: Start from RAM, base 0
+
+1: Start from flash_base + 0x10070
+
+2: Start from flash_base + 0x30070
+
+When using 1 or 2, the image is supposed to be launched
+from miniboot that boots the first U-Boot image found in
+flash.
+For miniboot code, description, see www.opensource.se
