So I've done: I'm not familiar with this device, but you appear to be missing a mapping driver (see drivers/mtd/maps, the most common being "physmap"). You'll likely need to know the physical address and size of your flash device. Once addresses are known, then the xyz_probe routines will be called to identify the device supposedly there. I could be way off base, maybe the "firmware hub" works more magically. My description is more for flash that is soldered on the board. -R
