From 86c2072be6f3c2150cc35f00233f2c31bdba2745 Mon Sep 17 00:00:00 2001 From: Mike Dunn Date: Wed, 25 Apr 2012 12:06:05 -0700 Subject: mtd: ecc_strength is at ecc step granularity MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ecc_strength element of mtd_info will be the strength of one ecc step, not of the entire writesize, as was previously planned. This is the appropriate way because, as was pointed out¹, bit errors in excess of the strength of one step can cause a hard error if they all occur within the same ecc region. ¹ http://lists.infradead.org/pipermail/linux-mtd/2012-March/040313.html Signed-off-by: Mike Dunn Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse --- drivers/mtd/nand/nand_base.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/mtd/nand/nand_base.c') diff --git a/drivers/mtd/nand/nand_base.c b/drivers/mtd/nand/nand_base.c index 512066e3d143..671f228d4c7c 100644 --- a/drivers/mtd/nand/nand_base.c +++ b/drivers/mtd/nand/nand_base.c @@ -3487,7 +3487,7 @@ int nand_scan_tail(struct mtd_info *mtd) /* propagate ecc info to mtd_info */ mtd->ecclayout = chip->ecc.layout; - mtd->ecc_strength = chip->ecc.strength * chip->ecc.steps; + mtd->ecc_strength = chip->ecc.strength; /* Check, if we should skip the bad block table scan */ if (chip->options & NAND_SKIP_BBTSCAN) -- cgit v1.2.3
