1002f964aa7SSimon Glass	  The debug UART is intended for use very early in U-Boot to debug

1022f964aa7SSimon Glass
1032f964aa7SSimon Glass	  To use it you should:
1042f964aa7SSimon Glass	  - Make sure your UART supports this interface
1052f964aa7SSimon Glass	  - Enable CONFIG_DEBUG_UART
1062f964aa7SSimon Glass	  - Enable the CONFIG for your UART to tell it to provide this interface
1072f964aa7SSimon Glass	        (e.g. CONFIG_DEBUG_UART_NS16550)

1152f964aa7SSimon Glass	  If your UART does not support this interface you can probably add
1162f964aa7SSimon Glass	  support quite easily. Remember that you cannot use driver model and
1172f964aa7SSimon Glass	  it is preferred to use no stack.
