NAK.

Patch doesn't work. After applying I get the following messages on Kilauea:

=> nand write 100000 0 100000

NAND write: device 0 offset 0x0, size 0x0
0 bytes written: OK
=> nand read 200000 0 100000

NAND read: device 0 offset 0x0, size 0x0
0 bytes read: OK

So nothing is read/written at all. This is how it behaves without this patch:

=> nand write 100000 0 100000

NAND write: device 0 offset 0x0, size 0x100000
1048576 bytes written: OK
=> nand read 200000 0 100000

NAND read: device 0 offset 0x0, size 0x100000
1048576 bytes read: OK

Best regards,
Stefan
