Andrew Lunn b5e12229a4 ARM: Orion5x - Restore parts of io.h, with rework ... Commit 4d5fc58dbe (ARM: remove bunch of now unused mach/io.h files) removed the orion5x io.h. Unfortunately, this is still needed for the definition of IO_SPACE_LIMIT which overrides the default 64K. All Orion based systems have 1Mbyte of IO space per PCI[e] bus, and try to request_resource() this size. Orion5x has two such PCI buses. It is likely that the original, removed version, was broken. This version might be less broken. However, it has not been tested on hardware with a PCI card, let alone hardware with a PCI card with IO capabilities.
