Hi,
You can you use the CFI driver in /u-boot-1.1.1/drivers/cfi_flash.c. it's generic and working. I have used it with these boards: IceCube(MPC5200) and EP8260 without modification.
Ahh... thanks for the hint. But anyway... the u-boot readme says an own flash.c was a minimum requirement for a port. If the generic driver works, why do people write customs flash.c's at all? All modern flash chips seem to support CFI anyway. Is there an example for a port that "only" uses the cfi_flash.c so I can take a look on it?
Best regards,

Peter,
The MPC85xx ADS and CDS boards are all currently using the CFI driver. They were originally coded using a part-specific flash.c, but they have since been converted to the generic CFI driver.
Thanks, jdl
