Board?
"Oops" is not a term I am familiar with other than as an exclamation -
can you elaborate please?

Please replace these with the GetMmioOperations call, as designed.
In fact, please provide an additional patch deleting all of the direct
SwapMmio* functions from IoAccessLib.h and changing all of the
SwapMmio* function definitions in IoAccessLib.c to STATIC to prevent
future accidental direct use.
