Hi Avi,

Something is going wrong with the flash devices. It can be reproduced
with the microblaze image on the wiki, you'll see the kernel complain
with:
pflash_write: Unimplemented flash cmd sequence (offset 00000000, wcycle 0x0 cmd 
0x0 value 0xf0)
of-flash a0000000.flash: do_map_probe() failed

When it should be saying:
a0000000.flash: Found 1 x8 devices at 0x0 in 8-bit bank. Manufacturer ID 
0x000000 Chip ID 0x000000
Intel/Sharp Extended Query Table at 0x0031

Cheers
