+  @param[in] DataSize       The size, in bytes, of ResetData.
+  @param[in] ResetData      For a ResetType of EfiResetCold, EfiResetWarm, or EfiResetShutdown
+                            the data buffer starts with a Null-terminated string, optionally
+                            followed by additional binary data. The string is a description

+                            system reset. ResetData is only valid if ResetStatus is something
+                            other than EFI_SUCCESS unless the ResetType is EfiResetPlatformSpecific
+                            where a minimum amount of ResetData is always required.
