    Subject[PATCH 1/5] Introduce CONFIG_GENERIC_IO
    Date
    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.
