|  | The debug UART is intended for use very early in U-Boot to debug |

|  |  | 
|  | 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 |
