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]:
