From 4ccd5510e50b5675227a1fe0e5ca099d333f637d Mon Sep 17 00:00:00 2001 From: Wolfgang Denk Date: Tue, 29 Jun 2010 01:33:35 +0200 Subject: [PATCH] MPC512x: workaround data corruption for unaligned local bus accesses Commit 460c2ce3 "MPC5200: workaround data corruption for unaligned local bus accesses" fixed the problem for MPC5200 only, but MPC512x is affected as well, so apply the same fix here, too.
