+         Some boards need to set things up before the debug UART can be used.
+         On these boards a call to debug_uart_init() is insufficient. When
+         this option is enabled, the function board_debug_uart_init() will
+         be called when debug_uart_init() is called. You can put any code
+         here that is needed to set up the UART ready for use, such as set
