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

If this is the formal word as used in official documentation, it still
needs listing in a glossary in the file comment header.

Can you flip the two above lines around to get them in order?

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.
