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.
