| 10 | for displaying messages while U-Boot is running. It also brings in |
| 11 | printf() and panic() functions. This should normally be enabled |
| 12 | unless there are space reasons not to. If you just need to disable |

| 200 | help |
| 201 | The debug UART is intended for use very early in U-Boot to debug |
| 202 | problems when an ICE or other debug mechanism is not available. |
| 203 | |
| 204 | To use it you should: |
| 205 | - Make sure your UART supports this interface |
| 206 | - Enable CONFIG_DEBUG_UART |
| 207 | - Enable the CONFIG for your UART to tell it to provide this interface |
| 208 | (e.g. CONFIG_DEBUG_UART_NS16550) |
| 209 | - Define the required settings as needed (see below) |
| 210 | - Call debug_uart_init() before use |
| 211 | - Call debug_uart_putc() to output a character |
| 212 | |
| 213 | Depending on your platform it may be possible to use this UART before |
| 214 | a stack is available. |
| 215 | |
| 216 | If your UART does not support this interface you can probably add |
| 217 | support quite easily. Remember that you cannot use driver model and |
| 218 | it is preferred to use no stack. |
| 219 | |
| 220 | You must not use this UART once driver model is working and the |
| 221 | serial drivers are up and running (done in serial_init()). Otherwise |
| 222 | the drivers may conflict and you will get strange output. |
