Support for the upcoming NetBSD/Amiga Hypercom driver family:
...
* support chip clocks != COM_FREQ, by introducing sc_frequency (for the
mainline code) and adding a frequency parameter right after the rate
parameter to comcnattach() and com_kgdb_attach().
- Make com_isa and com_multi initialize sc_frequency to COM_FREQ.
- Make i386/machdep.c and alpha/dec_xxx.c call com*attach() with the freq.
parameter.
* supio_attach_args get two more fields: a sc_ipl and a sc_arg, both ints.
- com_supio uses the first for interupt establishment (all childs will, as
soon as they exist) and the 2nd for sc_frequency.
- drsupio passes sc_ipl alway as 5, and for the "com"s, sc_arg as 16*115200
- hyper will pass sc_ipl as 6, and sc_arg as 16 * 460800

From page 6-9 of "Alpha AXP Architecture Reference Manual, Second Edition":
...
An IMB intruction must be executed after software or I/O devices
write into the instruction stream or modify the instruction
stream virtual address mapping, and before the new value is
fetched as an instruction.
We were missing calls to IMB after mappings were changed, which caused
systems with large I-caches (e.g. my AlphaStation 500) to fail miserably
when mapping in new pages of program text, or when context switching
(I couldn't even get the shell from init!).

Update for Chris Demetriou's changes made to the bus.h interface:
...
- bus_space_copy -> bus_space_copy_region (for consistency)
- "cacheable" argument becomes a "flags" argument instead, with
BUS_SPACE_MAP_CACHEABLE and BUS_SPACE_MAP_LINEAR flags currently
defined.

Add support for DDB (in-kernel debugger) to NetBSD/alpha, based on
...
such code for Mach 3's Alpha port. Initially reworked for NetBSD/alpha
by Chris Demetriou, and then heavily hacked on by me. Works, but is still
a little rough around the edges. Known problems:
- Error recovery could be improved a bit.
- Back traces don't work.
- Single-stepping can be flaky, at times. (Alpha doesn't have hardware
support for single-stepping, and I'm not entirely convinced the
MI DDB software-emulated single-stepping logic is 100% correct.)
- Logic for when to drop into DDB needs some improvement.

cflush, rdval, wripir, and wrval are used in multi-processor environments.

Two video-related changes:
...
- Only set mac68k_vidphys if we're on a machine that we couldn't get
the Mac OS memory map.
- If we could get the Mac OS memory map, use the framebuffer size found
by get_mapping() rather than the size calculated using the Booter
environment.
