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. Signed-off-by: Tetsuyuki Kobayashi <koba@kmckk.co.jp> Tested-by: Gary Thomas <gary@mlbassoc.com>
