+ 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.
+ @retval EFI_ACCESS_DENIED The file specified by File and FileBuffer did not
+ authenticate, and the platform policy dictates that the DXE
+ Foundation many not use File.
