   1 ## @file
   2 # A hook-in library for:
   3 # - MdeModulePkg/Universal/Variable/Pei/VariablePei.inf
   4 # - MdeModulePkg/Universal/Variable/RuntimeDxe/VariableRuntimeDxe.inf
   5 # - MdeModulePkg/Universal/Variable/RuntimeDxe/VariableSmm.inf
   6 #
   7 # Plugging this library instance into one of the above modules makes that
   8 # variable service backend wait for another platform module to dynamically
   9 # initialize or verify EFI_FIRMWARE_VOLUME_HEADER and VARIABLE_STORE_HEADER in
  10 # the non-volatile variable store FVB device. The initialization / verification
  11 # is signaled by installing gEdkiiNvVarStoreFormattedGuid into the
  12 # phase-matching PPI or protocol database, with a NULL interface. (Note that
  13 # installing gEdkiiNvVarStoreFormattedGuid into either the DXE or the MM
  14 # protocol database will unblock VariableSmm -- refer to EFI_SECTION_MM_DEPEX
  15 # in the PI spec.)
