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(?)
CMA102 CONFIG_CMA102 32MB ram, 2 ser, 1 par, rtc, dipsw,
2x16 lcd
CMA111 CONFIG_CMA111 32MB ram, 1MB flash, 4 ser, 1 par,

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:

CMA278-603EV CONFIG_CMA278_603EV PPC603ev CPU, 66MHz clock, 512K EPROM,

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.

Written by Thomas.Lange@corelatus.com 010805
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
