V3 PBC, and use them in the bus mem tag and the bus dma tag on the
P-4032. This allows us to get much further when PMON has configured
the PBC using the old-style PCI address map.
support the P-5064, which has a QED RM5xxx CPU soldered on.
There is some skeletal support for the P-4032 (an older board, which
had an R4xxx CPU). There are some placeholders for the P-6032, which
is their newest board, but no real code yet (the P-6032 has a different
PCI controller, the Algorithmics BONITO).
There are still some (apprently softintr-related) problems with the
algor kernel, but it works well-enough to self-host.
Kudos to Allegro Networks for loaning me a P-5064 board on which to do
the port.
