Support for Astro/Elroy is only a part of the game, the smaller and
simpler part. The more important part is support for PA 2.0 CPUs. This
is not trivial as it involves extensions to the uvm(9) / pmap(9) code
and possibly to the firmware interface.=20
Once we have PA 2.0 support in 32 bit mode we will be able to support
e.g. the C10 / C20 / C360 and D.0 verry soon. This machines
have an IO system very similar to the PA700 machines.
I already have a B2000 to work on. Unfortunately I am clueless in the
uvm(9) / pmap(9) department and have no time to dig into this. So I have
to leave this to someone else.
