Hi,
    I have a PPC405GP based board with a single AMD compatible Toshiba
TC58FVB321FT 4MB flash in word mode. The chip is physically mapped to
address 0x8000000 and according to the Data Sheet, is CFI compatible. I
believe I have properly configured the kernel but I can't seem to get my
chip identified. Am I missing sonething? Any help is greatly appreciated!!

This is my config:
