I think this is both overkill and incomplete, at the same time :) - Incomplete because only one IoLib instance gets the implementation. - Overkill because you can easily use the SwapBytes16, SwapBytes32, SwapBytes64 functions -- also from BaseLib --, for transforming MmioWrite arguments and MmioRead results.
