   For each RMR region, the test verifies that:
     1) An EFI memory map descriptor fully encompasses the RMR region, and
     2) That descriptor's memory type is acceptable, i.e. EfiReservedMemoryType

   If an RMR region is not found in the memory map, or is found but is not one of
   the acceptable memory types, the test fails.
