[parisc-linux] Success: My E55 (9000/856) runs bash-2.04 via PDC

[Christoph Plattner]

Hello PA-RISC community.

Again and again I want to have my E55 running Linux, but the problem
is the serial lines (8-port MDP) is a proprietary interface. So I needed
a solution. 

I had the idea to use the PDC console, months ago.
Today hacked a driver (template was serial.c) for a polling PDC device 
driver. I called it pdc_drv.c, the device is "ttyQ0", with MAJOR 30,
MINOR 0
and I use a polling period of 30ms (enough for a serial console i/f).

Because I have not further implemented the internel console i/f for my
driver, I used the hack with the link of
	/dev/console --> /dev/ttyQ0
And my machine boots up via NFS !

Perhaps we can make a "driver" out of this "hack" !

In my driver I also use the hack, I have done for the serial.c, that
with `^\' I can reboot ( machine_restart() ) the computer to work
remote on it !

With friendly regards

	Christoph P.
