1052f964aa7SSimon Glass	  The debug UART is intended for use very early in U-Boot to debug

1072f964aa7SSimon Glass
1082f964aa7SSimon Glass	  To use it you should:
1092f964aa7SSimon Glass	  - Make sure your UART supports this interface
1102f964aa7SSimon Glass	  - Enable CONFIG_DEBUG_UART
1112f964aa7SSimon Glass	  - Enable the CONFIG for your UART to tell it to provide this interface
1122f964aa7SSimon Glass	        (e.g. CONFIG_DEBUG_UART_NS16550)
1132f964aa7SSimon Glass	  - Define the required settings as needed (see below)

1202f964aa7SSimon Glass	  If your UART does not support this interface you can probably add
1212f964aa7SSimon Glass	  support quite easily. Remember that you cannot use driver model and
