Mpc5125 nfc hw ecc problems

[Daniel Mosquera]

Hi,

I'm trying to port the nfc nand driver from 2.6.39.1 linux kernel to 3.14.4
using 4k nand blocks and 2k page size and 24bit hw ecc.

At the current time I have been able to make ecc, page read, and page write
to work but I cannot make oob read and write to work.

The main problem I'm facing is that I don't know how the ecc layout in the
spare area works in mpc5125.

Please, could anybody tell where I could get information about how to tell
linux the correct ecc oob parameters?

Thanks in advance,
Daniel
