2009-06-04sh: 16-bit get_unaligned() sh4a fixMagnus Damm
This patch fixes the 16-bit case of the sh4a specific unaligned access implementation. Without this patch the 16-bit version of sh4a get_unaligned() results in a 32-bit read which may read more data than intended and/or cross page boundaries. Unbreaks mtd NOR write handling on Migo-R.

2008-12-22sh: Provide optimized unaligned loads on SH-4A.Paul Mundt
This adds support for unaligned loads on SH-4A, using the SH-4A's neutered movua.l instruction. As movua.l is r0-inspired, stores are still handled through the packed struct. Based on asm-generic/unaligned.h by Harvey Harrison. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
