Hmmm. When I understood Tolunay correctly (Tolunay, please correct me if I am 
wrong here), he _does_ want to use most of the CFI drivers functions like 
erasing and programming for those non CFI compatible FLASH's too. Most of 
those devices are kind of AMD compatible, so this should be possible with not 
too many changes.

If we don't use this code, then merging those devices into this driver doesn't 
make much sense to me anymore.

Best regards,
