+Routine Description:
+ Check to see if an address range is in the EFI GCD memory map.
+ 
+ This is all of GCD for system memory passed to DXE Core. FV 
+ mapping and other device mapped into system memory are not
+ inlcuded in the check. 
+
+Arguments:
+  Index      - Which memory region to use
+  MemoryBase - Return Base address of memory region
+  MemorySize - Return size in bytes of the memory region
+
+Returns:
+  TRUE -  Address is in the EFI GCD memory map
+  FALSE - Address is NOT in memory map
