           This driver supports the built-in serial ports of the Motorola ColdFire
           family of CPUs.
+          This driver is deprecated because it supports only the old interface
+          for serial drivers and features like magic keys are not working.
+          Please switch to the new style driver because this driver will be
+          removed soon.
