          You will need to provide parameters to make this work. The driver will
          be available until the real driver-model serial is running.

+         Select this to enable a debug UART using the ARM JTAG DCC port.
+         The DCC port can be used for very early debugging and doesn't require
+         any additional setting like address/baudrate/clock. On systems without
+         any serial interface this is the easiest way how to get console.
+         Every ARM core has own DCC port which is the part of debug interface.
+         This port is available at least on ARMv6, ARMv7, ARMv8 and XScale
+         architectures.
