I am using kernel 2.6.10 with patched cvs mtd and my flash mapping
driver. I also add debug msg on mount_block_root. The return value is
ENXIO. I am really get mess , because the cfi proded the flash
successfully, but final result is "no such a device". Does anyone have
ideas on this?
NOR flash driver (size->0x800000 mem->0x10000000)
NOR Flash 1: Found 1 x8 devices at 0x0 in 8-bit bank
Amd/Fujitsu Extended Query Table at 0x0040
NOR Flash 1: CFI does not contain boot bank location. Assuming top.
number of CFI chips: 1
