Er, I mean that calling the 'cfi_probe' function should return you a full
MTD driver for the appropriate chip. You don't need to know the details,
except that you need to turn on the appropriate CFI probing and AMD command
set code in your kernel.

See drivers/mtd/maps/physmap.c and configure it with the appropriate
parameters for how the flash is wired up on your boards.
