  If the resources can not be allocated for EFI_PEI_FIRMWARE_VOLUME_INFO2_PPI, then ASSERT().\r
  If the EFI_PEI_FIRMWARE_VOLUME_INFO2_PPI can not be installed, then ASSERT().\r

  @param  FvFormat             Unique identifier of the format of the memory-mapped\r
                               firmware volume.  This parameter is optional and\r
                               may be NULL.  If NULL is specified, the\r
                               EFI_FIRMWARE_FILE_SYSTEM2_GUID format is assumed.\r
  @param  FvInfo               Points to a buffer which allows the\r
                               EFI_PEI_FIRMWARE_VOLUME_PPI to process the volume.\r
                               The format of this buffer is specific to the FvFormat.\r
                               For memory-mapped firmware volumes, this typically\r
                               points to the first byte of the firmware volume.\r
  @param  FvInfoSize           The size, in bytes, of FvInfo. For memory-mapped\r
                               firmware volumes, this is typically the size of\r
                               the firmware volume.\r
  @param  ParentFvName         If the new firmware volume originated from a file\r
                               in a different firmware volume, then this parameter\r
                               specifies the GUID name of the originating firmware\r
                               volume. Otherwise, this parameter must be NULL.\r
  @param  ParentFileName       If the new firmware volume originated from a file\r
                               in a different firmware volume, then this parameter\r
                               specifies the GUID file name of the originating\r
                               firmware file. Otherwise, this parameter must be NULL.\r
  @param  AuthenticationStatus Authentication Status\r
