[parisc-linux] Serial console settings?

[Christoph Plattner]

.. Further the serial console speed has to be set, if Linux does
not use the PDC console (new feature for E55 and other machines with
proprietary hardware). The speed setting is done via kernel command
line parameter like

	console=ttyS0,38400

For more details at this point see under
linux/Documentation/serial-console.txt
