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.

	  CONFIG_SYS_NS16550_PORT_MAPPED - indicates that port I/O is used for
	     access. If not enabled, then the UART is memory-mapped.
	  CONFIG_SYS_NS16550_MEM32 - if memory-mapped, indicates that 32-bit
	     access should be used (instead of 8-bit)
	  CONFIG_SYS_NS16550_REG_SIZE - indicates register width and also
	     endianness. If positive, big-endian access is used. If negative,
	     little-endian is used.

	  It is not a good practice for a driver to be statically configured,
	  since it prevents the same driver being used for different types of

config SANDBOX_SERIAL
	bool "Sandbox UART support"
	depends on SANDBOX
	help
	  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
	     -t cooked		Cooked mode, Ctrl-C terminates
