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