[parisc-linux] Any docs on the 715?

There are two kinds of 715;  if you're lucky, you've got a "new" 715,
which has (really, check the hardware database for details) Lasi and
a PA7100LC, both documented, and undocumented graphics (all graphics
is).  There is very little difference between such 715s and 712s.

If you're unlucky (like me), you've got an "old" 715, which has ASP
(a Lasi predecessor) and what I believe is a PA7100.

Here's the list of things that work on the two boxes (* for things I
haven't actually checked, but believe should work):

715 old:
	network (10 mbit/s ethernet with a 10 base t transceiver)
	1 bpp unaccelerated framebuffer
	keyboard (HIL) *
	sound *
	serial *

715 new:
	network *
	1bpp unaccelerated framebuffer *
	keyboard (either PS/2 or HIL, both should work) *
	sound *
	serial *

I don't know about the 715 scsi chip, the eisa slot, parallel;
I don't think anyone has worked out how to use the LEDs yet.
