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.
