Architectures like xtensa, arc, can be converted to GENERIC_IOREMAP, to take standard ioremap_prot() and ioremap_xxx() way. But they have ARCH specific handling for ioremap() method, then standard ioremap() method. In oder to convert them to take GENERIC_IOREMAP method, allow ARCH to have its own ioremap definition. This is a preparation patch, no functionality change. Signed-off-by: Baoquan He <bhe@redhat.com> --- include/asm-generic/io.h | 3 +++ 1 file changed, 3 insertions(+)
