From ff02f139804f3cb61414f7bbcbfdaa0279e3efae Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Fri, 1 Feb 2008 09:38:29 +0100 Subject: ppc4xx: Fix ndfc HW ECC byte order The current ndfc HW ECC implementation swaps the first two ECC bytes. But the 4xx NDFC already uses the SMC (Smart Media Card) ECC ordering, so this swapping in the HW ECC driver is bogus. This patch fixes this problem and now really uses the SMC ECC byte order. Thanks to Sean MacLennan for pointing this out.
