+ Some boards need to set things up before the debug UART can be used.

+ 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:
