[parisc-linux] iodc console patch

[Thomas Bogendoerfer]

To get a sash prompt on my 715/33 I need the patch below. Even if this
patch isn't release quality something like that is needed to get the
iodc console going.

Because I still have some problems with the first few printed lines, I
haven't checked it into cvs. Hope it helps others as well. Ohh and changing
"console=ttyS0" to "console=tty" in boot_code/ipl_c.c is required, too.

Thomas.

I've just checked in something similar.  You should also disable
CONFIG_VT_CONSOLE, or you'll see all lines printed twice.  I think it
will now work out of the box for the 715/33 if you have the right .config.

*ahem*.  Of course, if you do, it will be unable to open an initial
console and panic.  Oops.  Don't do this for the moment :-)
