Subject: Introduce CONFIG_GENERIC_IO
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=087fafd15204fb7a5df44b635ed3d3f4348f2d5e;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

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.
