-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.
