I can return your question: why does the CFI exist?. Have a look at the u-boot-1.1.2/board/ppm8260/strataflash.c that is an example for a port that "only" uses the cfi_flash.c.

Good luck

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,
