Use for 1bit hamming the old layout. Please merge patch 1 and 2 so that we end up with a simple/self-contained patch that can be backported to stable kernels. > > Signed-off-by: Alexander Couzens <lynxis@fe80.eu> > --- > drivers/mtd/nand/nand_base.c | 6 +++++- > 1 file changed, 5 insertions(+), 1 deletion(-) > > diff --git a/drivers/mtd/nand/nand_base.c b/drivers/mtd/nand/nand_base.c > index daf3df157885..6a9e99377181 100644 > --- a/drivers/mtd/nand/nand_base.c > +++ b/drivers/mtd/nand/nand_base.c > @@ -4724,7 +4724,11 @@ int nand_scan_tail(struct mtd_info *mtd) > break; > case 64: > case 128: > - mtd_set_ooblayout(mtd, &nand_ooblayout_lp_ops); > + if (ecc->algo == NAND_ECC_HAMMING && ecc->strength == 1) > + mtd_set_ooblayout(mtd, > + &nand_ooblayout_lp_hamming_ops); > + else > + mtd_set_ooblayout(mtd, &nand_ooblayout_lp_ops); Why not unconditionally setting it to nand_ooblayout_lp_hamming_ops to restore the initial behavior. If one wants to use the new "large page" layout he can still explicitly assign it (which is a good practice anyway). > break; > default: > WARN(1, "No oob scheme defined for oobsize %d\n", ______________________________________________________ Linux MTD discussion mailing list http://lists.infradead.org/mailman/listinfo/linux-mtd/

commit 41b207a70d3a ("mtd: nand: implement the default mtd_ooblayout_ops") uses a different ooblayout for platforms which doesn't set the layout by itself. Use for 1bit hamming the old layout.
