From 5eb497429ef065083d75ca0bbc61d421a17fcec1 Mon Sep 17 00:00:00 2001 From: Tetsuyuki Kobayashi Date: Sun, 1 Jul 2012 23:42:10 +0000 Subject: arm: armv7: add compile option -mno-unaligned-access if available Recent compiler generates unaligned memory access in armv7 default. But current U-Boot does not allow unaligned memory access, so it causes data abort exception. This patch add compile option "-mno-unaligned-access" if it is available.
