-/// A memory region that describes system memory that has not been accepted
-/// by a corresponding call to the underlying isolation architecture.
-///
-/// This memory region has not been defined in PI spec, so it is defined in
-/// PrePiDxeCis.h. And it is defined in the format of captial letters
-/// because only capital letters are allowed to be used for #define declarations.
-///
-/// After this memory region is defined in PI spec, it should be a value in
-/// EFI_GCD_MEMORY_TYPE in PiDxeCis.h.
