+Module Name:
+
+  Crc32.c
+
+Abstract:
+
+  CalculateCrc32 Boot Services as defined in DXE CIS.
+
+  This Boot Services is in the Runtime Driver because this service is
+  also required by SetVirtualAddressMap() when the EFI System Table and
+  EFI Runtime Services Table are converted from physical address to 
+  virtual addresses.  This requires that the 32-bit CRC be recomputed.
