Looking at the first 2 patches on nand_base.c, it seems that the HW
ECC layout for small pages will be the same (ecc at offsets 0,1,2,3)
wich is good (because it's the only possible place).

For large pages, the HW ECC layout will change from [60,61,62,63] to
[2,3,4,5]. The ecc will still be correct, but as david said, the
compatibility won't.
