sh: avoid multiple definition errors with cache funcs
Recent builds for SH4 boards fail with a lot of errors like: cmd_mem.o: In function 'dcache_invalid_range': include/asm/cache.h:25: multiple definition of 'dcache_invalid_range' include/asm/cache.h:25: first defined here This is due to the funcs being defined in the header, but not static or inline or extern. So move them to the sh4-specific cache.c file. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
