I don’t think a warning message around EFI_MEMORY_UC is useful… it’s typical to
request such a mapping for device MMIO (e.g. PciHostBridgeDxe,
NonDiscoverablePciDeviceDxe, etc). On a system without PBMT yeah the M mode

Thank you.
OK, that's logically consistent.
So we'd need an ArmLibNull in MdePkg until ArmLib itself migrates there
(ideally subsumed into BaseLib).
But the dependency in .inf should still be able to be declared under
[LibraryClasses.AArch64, LibraryClasses.ARM]?
