Say Y here if you wish the debug print routes to direct
their output to a PL01x Primecell UART. You can use
this option to provide the parameters for the 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.
