+                                    For example, system error may be not supported to process and Platform should have mechanism to reset system to manufacture mode.
+                                    Another, if system and user variables are wanted to be distinguished to process, the interface must be called after EndOfDxe.
+  @retval EFI_OUT_OF_RESOURCES      Not enough resource to process the error.
+  @retval EFI_INVALID_PARAMETER     The specified Flag or Type is an invalid value.
+  @retval Others                    Other failure occurs.
