You must never copy any code without trying to understand it. When
adapting code from another board, you need to understand not only your
own hardware in detail, but also the hardware you are copying from.

In your case, you should not use the old flash driver in flash.c at
all. Remove that file, and use the CFI flash driver instead.

Best regards,

Wolfgang Denk

Dear Wolfgang Denk:
    Because AM29LV040B driver has been used on VxWorks and it works
fine, so code of flash.c is taken from AM29LV040B driver. I think it
should be good, but bad!

Best regard
