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