* common: Make sure arch-specific map_sysmem() is definedJoe Hershberger2015-04-18-0/+1
| | | | | | | | | | | In the case where the arch defines a custom map_sysmem(), make sure that including just mapmem.h is sufficient to have these functions as they are when the arch does not override it. Also split the non-arch specific functions out of common.h Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: Simon Glass <sjg@chromium.org>
