config DEBUG_UART
	bool "Enable an early debug UART for debugging"
	help
	  The debug UART is intended for use very early in U-Boot to debug
	  problems when an ICE or other debug mechanism is not available.

	  To use it you should:
	  - Make sure your UART supports this interface
	  - Enable CONFIG_DEBUG_UART
	  - Enable the CONFIG for your UART to tell it to provide this interface
	        (e.g. CONFIG_DEBUG_UART_NS16550)
	  - Define the required settings as needed (see below)
	  - Call debug_uart_init() before use
	  - Call debug_uart_putc() to output a character

	  Depending on your platform it may be possible to use this UART before
	  a stack is available.

	  If your UART does not support this interface you can probably add
	  support quite easily. Remember that you cannot use driver model and
	  it is preferred to use no stack.

	  You must not use this UART once driver model is working and the
	  serial drivers are up and running (done in serial_init()). Otherwise
	  the drivers may conflict and you will get strange output.

	help
	  Enable this option to show a message when the debug UART is ready
	  for use. You will see a message like "<debug_uart> " as soon as

	bool "Bypass output when no connection"
	depends on ALTERA_JTAG_UART
	help
	  Bypass console output and keep going even if there is no JTAG
	  terminal connection with the host. The console output will resume

	help
	  Support NS16550 UART or compatible. This can be enabled in the
	  device tree with the correct input clock frequency. If the input
	  clock frequency is not defined in the device tree, the macro
	  CONFIG_SYS_NS16550_CLK defined in a legacy board header file will
	  be used. It can be a constant or a function to get clock, eg,

	  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
