We have just made our own MCF5208 board with 32-bit SDRAM and Flash
memory. The original M5208EVB uses an 16-bit design. Now I would like to
know, what do I need to change to get my mtd partition fully working
again in this design? It seems to access the flash memory in 16-bit
mode. We're using 2x 16-bit Flash memories S29JL032H. I only have to
know what to change for the 32-bit part Flash memory. Like for instance
do I need to change the #define BUSWIDTH 2 for this design in
linux-2.4.x/drivers/mtd/maps/m5208.c?
I would expect that you do need to change that to 4.
I've allready changed the flash bit width to 32-bit in block devices or
do i need to make more specific changes. Erasing an sector seems to work
almost fine. Except that it didn't fully erased the full memory range.
Where did you change this, what setting is it?
For the SDRAM I changed the SDRAM Processor type features to 32-bit plus
the changes in the files:
linux-2.4.x/arch/m68knommu/platform/5208/crt0_ram.S
linux-2.4.x/arch/m68knommu/platform/5208/ram.ld
I don't suspect any complication on this part unless anybody says I need
to change something specific?
Not to much is generally required of RAM, provided the DRAM
controller is actually setup properly.

Greg
