The code in the previous patch looks fine, but I'd prefer it if we
expose this as a separate library class, not ArmMmuLib
So please just add a new file, say,
ArmPkg/include/Library/StandaloneMmMmuLib.h, add only the functions
you need, and add it to the LibraryClasses section of ArmPkg.dec as a
new library class.
Then, you can modify the previous patch to include an updated .inf
that describes it as being an implementation of StandaloneMmMmuLib.
You can then also drop the unimplemented ArmConfigureMmu etc.
