Perhaps I need to try and be clearer here than I might have been in the
past. The consensus among off the shelf free software operating systems
is "just give me an EFI interface". This simplifies things on their end
if regardless of architecture it's the same interface. This means that
in U-Boot we need to treat EFI as one of the primary interfaces. Not a
novelty. Not a "some people might use". It is a frequent and commonly
used feature.
