| 17 | help |
| 18 | Say Y here if you wish the debug print routes to direct |
| 19 | their output to an 8250 UART. You can use this option |
| 20 | to provide the parameters for the 8250 UART rather than |
| 21 | selecting one of the platform specific options above if |
| 22 | you know the parameters for the port. |
| 23 | |
| 24 | This option is preferred over the platform specific |
| 25 | options; the platform specific options are deprecated |
| 26 | and will be soon removed. |
