Introduce CONFIG_GENERIC_IO
There are situations where CONFIG_HAS_IOMEM is too restrictive. For example CONFIG_MTD_NAND_NANDSIM depends on CONFIG_HAS_IOMEM but it works perfectly fine if an architecture without io memory just includes asm-generic/io.h or implements everything defined in it. UML is such a corner case. Signed-off-by: Richard Weinberger <richard@nod.at>
