502f964aa7SSimon Glass	  The debug UART is intended for use very early in U-Boot to debug
512f964aa7SSimon Glass	  problems when an ICE or other debug mechanism is not available.
522f964aa7SSimon Glass
532f964aa7SSimon Glass	  To use it you should:
542f964aa7SSimon Glass	  - Make sure your UART supports this interface
552f964aa7SSimon Glass	  - Enable CONFIG_DEBUG_UART
562f964aa7SSimon Glass	  - Enable the CONFIG for your UART to tell it to provide this interface
572f964aa7SSimon Glass	        (e.g. CONFIG_DEBUG_UART_NS16550)
582f964aa7SSimon Glass	  - Define the required settings as needed (see below)
592f964aa7SSimon Glass	  - Call debug_uart_init() before use
602f964aa7SSimon Glass	  - Call debug_uart_putc() to output a character

622f964aa7SSimon Glass	  Depending on your platform it may be possible to use this UART before
632f964aa7SSimon Glass	  a stack is available.
642f964aa7SSimon Glass
652f964aa7SSimon Glass	  If your UART does not support this interface you can probably add
662f964aa7SSimon Glass	  support quite easily. Remember that you cannot use driver model and
672f964aa7SSimon Glass	  it is preferred to use no stack.
682f964aa7SSimon Glass
692f964aa7SSimon Glass	  You must not use this UART once driver model is working and the
702f964aa7SSimon Glass	  serial drivers are up and running (done in serial_init()). Otherwise
712f964aa7SSimon Glass	  the drivers may conflict and you will get strange output.
