We are using CFI compliant flashes (S29GLXXXN) and I would like to know if it is really necessary to have a board specific driver, or if the cfi_flash.c driver is enough.
I recently ported U-Boot to a custom board utilizing Spansion S29GLxxxM chip. I used drivers/cfi_flash.c, but at least on this particular board it needed an additional patch. I haven't yet verified if this patch is really needed or if it's just an configuration issue.
I used a patch by Alex Bastos, that is available on u-boot-users list archives, look for this message [1]:
