boot device autodetection, using PROM's boot device environment variable.
...
This is a bit of a hack, as-is, since there's a lot of code that's
outright duplicated between the various files and because it doesn't
support detection of a network device as the root device. The
latter's not a problem yet, because NetBSD/Alpha can't load the kernel
from the network to begin with.

>Update for present reality (function names), clean up a bit (printfs,

>(which were normally #if 0'd out). Inspired by Multia/UDB support
>changes sent by Matt Thomas.
and:
>changes from Matt Thomas so that the Multia/UDB can attach its
>'com' interrupts, cleaned up some. Basically: if sharing type of
>new interrupt is different than what the hardware is currently set up

gross hack to get around the fact that there are currently devices with
...
common back-ends that live on multiple very-different busses (e.g. PCI and

this will allow the especially nasty (vtophys(va) | 0x40000000) expressions
to go away in favor of less nasty bus-specific function calls.
