+	  Select this to enable a seral UART for sandbox. This is required to
+	  operate correctly, otherwise you will see no serial output from
+	  sandbox. The emulated UART will display to the console and console
+	  input will be fed into the UART. This allows you to interact with
+	  U-Boot.
+
+	  The operation of the console is controlled by the -t command-line
+	  flag. In raw mode, U-Boot sees all characters from the terminal
+	  before they are processed, including Ctrl-C. In cooked mode, Ctrl-C
+	  is processed by the terminal, and terminates U-Boot. Valid options
+	  are:
+
+	     -t raw-with-sigs	Raw mode, Ctrl-C will terminate U-Boot
+	     -t raw		Raw mode, Ctrl-C is processed by U-Boot
