| 913 | Say Y here if you wish the debug print routes to direct |
| 914 | their output to a PL01x Primecell UART. You can use |
| 915 | this option to provide the parameters for the UART |
| 916 | rather than selecting one of the platform specific |
| 917 | options above if you know the parameters for the port. |
| 918 | |
| 919 | This option is preferred over the platform specific |
| 920 | options; the platform specific options are deprecated |
| 921 | and will be soon removed. |
