+ EFI MM Configuration Protocol as defined in the PI 1.5 specification.
+
+ This protocol is used to:
+ 1) report the portions of MMRAM regions which cannot be used for the MMRAM heap.
+ 2) register the MM Foundation entry point with the processor code. The entry
+ point will be invoked by the MM processor entry code.
