+  @param[in]    AuthenticationStatus  This is the authentication status returned from

+  @param[in]    File       This is a pointer to the device path of the file that is
+                           being dispatched. This will optionally be used for logging.
+  @param[in]    FileBuffer File buffer matches the input file device path.
+  @param[in]    FileSize   Size of File buffer matches the input file device path.
+  @param[in]    BootPolicy A boot policy that was used to call LoadImage() UEFI service.
+
+  @retval EFI_SUCCESS            The input file specified by File did authenticate, and the
+                                 platform policy dictates that the DXE Core may use File.

+                                 authenticate, and the platform policy dictates that the DXE
+                                 Foundation many not use File.
