From 1f7b1743d389fec616e9021012a03847f490cd18 Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Mon, 13 Feb 2012 15:46:27 -0600 Subject: Revert "nand: make 1-bit software ECC configurable" This reverts commit 4fee6c2f295f932b8febdc7ce8731ba045695fa5. It breaks boards that currently rely on soft-ecc, as pointed out here: http://patchwork.ozlabs.org/patch/140872/ The reverted patch should be resubmitted with documentation, and with the CONFIG_MTD_ECC_SOFT selected from every board that needs it. We could start by looking at what NAND driver the board selects, and whether that driver ever asks for soft ECC.
