+  Install a EFI_PEI_FIRMWARE_VOLUME_INFO PPI to inform PEI core about the existence of a new Firmware Volume.
+  
+  The function allocate the EFI_PEI_PPI_DESCRIPTOR structure and update the fields accordingly to parameter passed
+  in and install the PPI.
+  
+  @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
+                               typically the size of the firmware volume.
+  @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, 
+                               these should be NULL.
