DS5000/25 and maybe others i/o base addresses?

Hello everybody,

Florian, I'm curious how you handled the base address stuff for the scsi
driver. Let me explain why:

With compiling declance.c in the kernel I've succeeded, had to do a
dirty hack in Space.c, don't know why yet, will find out some time
later. declance.c is derived from sunlance.c because that has a lot
of generic LANCE code. With adepting for DS's I've started with the
initialization (after commenting out sparc specific parts of course)
and am a bit stuck with the base address stuff, for the only thing I
know that works is NetBSD and the NetBSD code tells me differently then
the PMAD-AA TURBOchannel Ethernet Module documentation does about the
Ethernet Module Adresses - the KN02 documentation refers to the Ethernet
Module specification.

And as far as my DS5000/25 concerns I have only the NetBSD output -
which I attached at the end - and that shows regretably only relative
base addresses. In other words any programming documentation about the
KN02CA system module is very welcome.

NetBSD says this at boottime:
