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. Signed-off-by: Scott Wood <scottwood@freescale.com>
