+  Report the information for a new discoveried FV in unknown format.
+  
+  If the EFI_PEI_FIRMWARE_VOLUME_PPI has not been install for specifical FV format, but
+  the FV in this FV format has been discoveried, then the information of this FV
+  will be cached into PEI_CORE_INSTANCE's UnknownFvInfo array.
+  Also a notification would be installed for unknown FV format guid, if EFI_PEI_FIRMWARE_VOLUME_PPI
+  is installed later by platform's PEIM, the original unknown FV will be processed by
+  using new installed EFI_PEI_FIRMWARE_VOLUME_PPI.
+  
+  @param PrivateData  Point to instance of PEI_CORE_INSTANCE
+  @param Format       Point to the unknown FV format guid.
+  @param FvInfo       Point to FvInfo buffer.
+  @param FvInfoSize   The size of FvInfo buffer.
+  
+  @retval EFI_OUT_OF_RESOURCES  The FV info array in PEI_CORE_INSTANCE has no more spaces.
+  @retval EFI_SUCCESS           Success to add the information for unknown FV.
