This file implements CalculateCrc32 Boot Services as defined in
|
|
Platform Initialization specification 1.0 VOLUME 2 DXE Core Interface.
|
|
|
|
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.
