  30   This PPI describes the location and format of a firmware volume.
  31   The FvFormat can be EFI_FIRMWARE_FILE_SYSTEM2_GUID or the GUID for
  32   a user-defined format. The  EFI_FIRMWARE_FILE_SYSTEM2_GUID is
  33   the PI Firmware Volume format.
  34
  35   @param  FvFormat      Unique identifier of the format of the memory-mapped firmware volume.
  36
  37   @param  FvInfo        Points to a buffer which allows the EFI_PEI_FIRMWARE_VOLUME_PPI to
  38                         process the volume. The format of this buffer is
  39                         specific to the FvFormat. For memory-mapped firmware volumes,
  40                         this typically points to the first byte of the firmware volume.
  41
  42   @param  FvInfoSize    Size of the data provided by FvInfo. For memory-mapped firmware volumes,
  43                         this is typically the size of the firmware volume.
  44
  45   @param  ParentFvName  If the firmware volume originally came from a firmware file,
  46                         then these point to the parent firmware volume
  47                         name and firmware volume file. If it did not originally come
  48                         from a firmware file, these should be NULL.
  49
  50   @param  ParentFileName  If the firmware volume originally came from a firmware file,
  51                         then these point to the parent firmware volume
  52                         name and firmware volume file. If it did not originally come
  53                         from a firmware file, these should be NULL.
