Help text

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.
