From ccdc50dc15dd81f33efa87779c846df3006a425b Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Wed, 26 Sep 2012 16:15:27 -0700 Subject: [PATCH] mtd: fsl_elbc_nand: remove unnecessary badblock_pattern Since the introduction of nand_create_default_bbt_descr() (now known as nand_create_badblock_pattern()) in commit 58373ff0afff4cc8ac40608872995f4d87eb72ec nand_chip.badblock_pattern will be dynamically calculated to the same 1-byte-length pattern that is required by fsl_elbc_nand. This custom badblock_pattern is no longer needed, then, and its removal may help facilitate further nand_bbt.c/nand_base.c cleanup in the future (one down, many to go?) Anyway, with nand_bbt.c fixed, this effectively reverts: commit 452db2724351ff3d9416a183a7955e00ab4e6ab4 [MTD] [NAND] fsl_elbc_nand: fix OOB workability for large page NAND chips Signed-off-by: Brian Norris Cc: Scott Wood Signed-off-by: Artem Bityutskiy --- drivers/mtd/nand/fsl_elbc_nand.c | 15 --------------- 1 file changed, 15 deletions(-) diff --git a/drivers/mtd/nand/fsl_elbc_nand.c b/drivers/mtd/nand/fsl_elbc_nand.c index cc1480a5e4c1..4c4d3e5bca18 100644 --- a/drivers/mtd/nand/fsl_elbc_nand.c +++ b/drivers/mtd/nand/fsl_elbc_nand.c @@ -108,20 +108,6 @@ static struct nand_ecclayout fsl_elbc_oob_lp_eccm1 = { .oobfree = { {1, 7}, {11, 13}, {27, 13}, {43, 13}, {59, 5} }, }; -/* - * fsl_elbc_oob_lp_eccm* specify that LP NAND's OOB free area starts at offset - * 1, so we have to adjust bad block pattern.
