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