I got several patches from here:

   https://github.com/MISL-EBU-System-SW/mainline-public.git

and now I have:

   pxa3xx-nand f10d0000.nand: This platform can't do DMA on this device
   NAND device: Manufacturer ID: 0x2c, Chip ID: 0xf1 (Micron MT29F1G08ABADAWP)
   NAND device: 128MiB, SLC, page size: 2048, OOB size: 64
   pxa3xx-nand f10d0000.nand: ECC strength 4 at page size 2048 is not supported
   pxa3xx-nand f10d0000.nand: failed to scan nand at cs 0

So I suppose I should modify function pxa_ecc_init() in file
drivers/mtd/nand/pxa3xx_nand.c in order to support my NAND chip, is
that right? Have you any advice for me about it? :)

Thanks a lot,

Rodolfo
