48557c65 2 This file implements CalculateCrc32 Boot Services as defined in\r
3 Platform Initialization specification 1.0 VOLUME 2 DXE Core Interface.\r
fb0b259e 4\r
9920ae74 5 This Boot Services is in the Runtime Driver because this service is\r
6 also required by SetVirtualAddressMap() when the EFI System Table and\r
7 EFI Runtime Services Table are converted from physical address to\r
48557c65 8 virtual addresses. This requires that the 32-bit CRC be recomputed.\r
