From 172106433b68bfcc25d025fca346021f005166b7 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Thu, 27 Oct 2011 04:59:59 -0400 Subject: 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.
