    ARM: Orion5x - Restore parts of io.h, with rework · b5e12229
    Andrew Lunn authored
    Commit 4d5fc58d (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.
