I think that if the serial chip on rtVAX are similar enough to the chip on the VXT2000 then it would be good to have support for both of them in the same driver.I have now created a subdirectory below arch/vax named rtv and try to put the needed stuff in there. I've copied the qsc files from OpenBSD, removed some stuff that's not needed (4 Lines in a chip) and will try to integrate that. Before I can do that I have to make an modified vsbus (since there are some other adresses on the rtVAX, uncommon to the rest).
Also, I think it is no reason to invent a new bus since there will be no need for it. The sgec is already in there (at mainbus as ze0) and adding the serial driver could be done in the same way.
The CPU is a CVAX so the same CPU definitions should be possible to use IMHO.
But the best thing is to get running now, then later things can be cleaned up :-)
