ARM: sh7372 ap4evb NOR Flash USB boot fix
Always use CS0 shadow area for NOR flash instead of regular CS0 memory area on ap4evb. When booting from CS0 NOR Flash the regular CS0 memory area is available, but when booting via USB the MASK ROM gets mapped to 0x0 which gets in the way for the NOR Flash. Always using CS0 shadow area works well for both NOR Flash boot and USB boot. Signed-off-by: Bastian Hecht <hechtb@gmail.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
