    sh: Support I/O space swapping where needed. · b7e68d68
    Paul Mundt authored
    This adopts a trimmed down version of the MIPS port mangling interface
    limited to the I/O swabbing for platforms that can't use little endian
    accessors. For platforms with mixed I/O spaces involving PCI it will
    still be necessary to enable byte swapping at the host controller level.
    Attention needs to be paid to all of host controller endianness, CPU
    endianness, and whether I/O accesses are explicitly swapped or not via
    SWAP_IO_SPACE. Fortunately the platforms that need this are in the
    minority.
