-/** @file
- Library functions that abstract areas of conflict between Tiano an UEFI 2.0.
-
- Help Port Framework/Tinao code that has conflicts with UEFI 2.0 by hiding the
- oldconflicts with library functions and supporting implementations of the old
- (EDK/EFI 1.10) and new (EDK II/UEFI 2.0) way. This module is a DXE driver as
- it contains DXE enum extensions for EFI event services.
