+ @param FvFormat Unique identifier of the format of the memory-mapped firmware volume.
+ If NULL is specified, EFI_FIRMWARE_FILE_SYSTEM2_GUID is used as the Format GUID.
+ @param FvInfo Points to a buffer which allows the EFI_PEI_FIRMWARE_VOLUME_PPI to
+ process the volume. The format of this buffer is specific to the FvFormat. For
+ memory-mapped firmware volumes, this typically points to the first byte of the
+ firmware volume.
+ @param FvInfoSize Size of the data provided by FvInfo. For memory-mapped firmware volumes, this is

+ @param ParentFvName If the firmware volume originally came from a firmware file, then these point to the
+ parent firmware volume name. If it did not originally come from a firmware file,
+ these should be NULL.
+ @param ParentFileName If the firmware volume originally came from a firmware file, then these point to the
+ firmware volume file. If it did not originally come from a firmware file,
