Subject: MPC512x: workaround data corruption for unaligned local bus accesses
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=4ccd5510e50b5675227a1fe0e5ca099d333f637d;p=u-boot.git

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.
