From bf4289cba02b8cf770ecd7959ca70839f0dd9d3c Mon Sep 17 00:00:00 2001 From: Jean-Christophe PLAGNIOL-VILLARD Date: Thu, 29 Dec 2011 14:43:24 +0800 Subject: ATMEL: fix nand ecc support So we can now choose for the board the ecc mode (ecc soft, soft bch, no ecc and hardware). Set ecc mode in the boards to soft as currently in the driver.
