this hardware alive is becoming increasingly difficult, and I should heed the
message sent by the three disks which have died on me over the last few days.
Noone sane will mourn these ports anyway. So long, and thanks for the fish.

dbatc. Add batc mapping support for 88110 systems as well.

- switch to perl for better data structures and (thus) speed
- fix a couple glitches in the interpretation of the stabs output
- compress the strings by putting them in one big array and overlaying
suffixes
- all sizes and offsets are <64k, so use u_short for them
This results in ~60% reduction in the resulting text size and it now
takes less than a second to create on fast platforms.

- the am7990_get() - now lance_get() - is unchanged.
- the interrupt acknowledge logic is unchanged, and will disable interrupts,
then acknowledge all interrupt conditions.
Add ILACC (79900) support (from NetBSD).
Both LANCE (am7990.c) and ILACC (am79900.c) code share as much common code
(lance.c) as possible. This affects all le(4) attachments, but the changes
are mostly mechanical, to split am7990-specific parts from lance-agnostic
parts.
Compile tested on all affected platforms. Tested on alpha, hp300, luna88k,
mvme88k, sparc, sparc64 and vax.

Add CWARNFLAGS to the command line when using -xassembler-with-cpp. We are
mostly interested in -Werror here.

and VME controller are supported; tod chip isn't supported yet (coming soon).
MVME236 memory boards are not supported and won't likely be (unless I get my
hands on one).
MVME181-1 boots multiuser (slowly) with MVME328 SCSI and MVME376 Ethernet
despite only having 8MB of memory onboard.
MVME180 untested; might need tweaking to get MVME SCSI and Ethernet boards
supported.
Many thanks to Matti Nummi for lending me an MVME181 board.

function pointers for all the board-specific code.
Add a bunch of `struct board' methods to cover most, if not all, of the
`per-board' logic. This allows most of the md drivers to be cleaned up and
no longer need to embed board-specific knowledge.

multiple tod routines in the near future.
Use the mi clock_ymdhms_to_secs and clock_secs_to_ymdhms routines.

#$%&#@! MC88410 chip. This will allow design-agonstic m88k-specific code to be
able to tell pure 88110 kernels apart from possible 88110+88410 ones.

using the -MD option to cc, with -MP, -MT, and -MF where needed, converting
"make depend" to a no-op. This increases parallelism for those using "make -j"
and keeps the dependencies up to date with each compilation automatically.
sparc and vax users will need to rebuild gcc with support for the
-M[PTF] options before config'ing with this diff.

since a large part of the structures and logic remains.
Since m88k has separate supervisor/user spaces, we can map physical memory 1:1
in supervisor space, and have the kernel virtual address space start from the
end of physical memory.
This allows us to switch to __HAVE_PMAP_DIRECT. And to get rid of the double
mapped sdt, since now their virtual and physical addresses will always match.
The upper bound of the kernel virtual memory space is now platform dependent,
until the code which relies upon some hardware devices being mapped 1:1 in
supervisor mode is updated to no longer require this (this is mainly a PITA on
luna88k, where onboard devices start at 0x40000000, leaving only 1GB of KVA at
the moment - still much better than the previous 512MB).
Tested on mvme88k only (187, 188, 197LE, 197DP). Other platforms ought to
work, aviion will be checked shortly and fixed if necessary. No known
OpenBSD/luna88k system in working condition at the moment.

early MD and late MI files must be split up so that vers.o can sneak

having it linked last is bad (on at least i386 and amd64) because the lapic
is mapped over the start of the data segment -- savecore(8) then reads the
version string for a fixed buffer space, and reads into the lapic area
causing unintended side-effects (at least on Intel X5570 and X5680)

the differences between these files. You will need a newer config(8) binary
to be able to build kernels.

result: kernels built without 'make depend'-provided information
(ie. the .depend file) are more likely to have their *.[Ss] file
compilations track changes to *.h files.
The "*.o: assym.h" dependencies listed are gotten from reading the
.depend output --- from the biggest kernel possible (ie. GENERIC.MP).
When an architecture changes in a substantial way (new .[sS] files),
the list should be updated in the prettiest way possible.
This is not encouraging people to skip 'make depend'; other issues are
not resolved and may be solved later with a change guenther is working
on. You can still screwed really easily, so continue running make
depend as config tells you.

two directories. in reality, because of how we place files, it has four:
.../arch/A, .../arch/A/A, .../arch/M, and .../arch/M/M
formalize this A/A and M/M scheme directly in the Makefiles, which makes
them a lot more similar

a few arches where toolchain limitations apply) will embed some symbolic
information about the various structs used within the kernel, and have
new ddb commands allowing struct display and some useful information
gathering. Kernel rodata increase varies accross platforms from ~150KB to
~300KB.
This option is not enabled by default.
