5b39541e48 New generic disk framework. Highlights: 
- New metrics handling.  Metrics are now kept in the new
	  `struct disk'.  Busy time is now stored as a timeval, and
	  transfer count in bytes.

	- Storage for disklabels is now dynamically allocated, so that
	  the size of the disk structure is not machine-dependent.

	- Several new functions for attaching and detaching disks, and
	  handling metrics calculation.

Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.

For usage and architectural details, see the forthcoming disk(9) manual
page.

6d6c652f18 New driver for the Sun SCSI-3 VME and 4/100-series SCSI "Weird" controllers, 
utilizing David Jones' new MI NCR 5380 code.  Ported from the sun3 ncr_si.c
and "sw" DMA code written by me.

This driver contains user-configurable "options", which can be set via the
"flags" directive in the kernel configuration file.  By default, only
DMA is enabled.  DMA completion interrupts and reselection may be enabled
by setting the appropriate bits with "flags".  See si.c for details.

Note that DMA completion interrupts and reselection don't yet work on the
4/100 controller.  I don't know why, and it's unlikely that I'll have
the opportunity to find out any time soon.  DMA does work, and results
in a considerable performance increase.

DMA, DMA completion interrupts, and reslection all work on my 4/260 (VME)
system with modern SCSI-II disks.

ee08e9085b Extend the size of the "soft" FIFOs which reportedly reduces the number 
of FIFO overflows on high baud rates.
However, doing so on all 4 ports would cost a whopping 64KB (at 4096 entries
per FIFO) of kernel memory. So, the FIFOs are now allocated at attach time
allowing the size for the keyboard and mouse ports to be reduced (to 128)
which should be adequate for the 1200 baud they use.

9bf3251e46 Lots of major and minor bug fixes and changes. 
- properly do MSG_IN handshaking, so we can actually receive multi-byte msgs.

There are a few trial-and-error bits at points where the docs I have are
particularly ambiguous about the state of chip and/or SCSI bus.

Things to do:
- more cleanup
- deal with MSG_OUT phase better
- keep some "config reg 3" bits per target (ie. FASTCLK and FASTSCSI).

54ec9fb697 Correct test for sun4 machines (thanks Chuck). 
Since uname currently does not allow to discriminate different sparc

if the returned strings starts with "SUN4-" a sun4 architecture is
assumed. This information is used to determine whether or not to strip
the a.out header off the 1st-stage bootblocks.

851669ceab cleaned up bootpath code: 
- v2 openprom disk boot generates "/sbus/esp/sd@3,0" which we translated
	into "/sbus@0,0/esp@0,0/sd@3,0"... this caused esp.c to reject
	the bootpath because it was looking for sbus slot/offset 0,0.
	changed the code to generate "/sbus0/esp0/sd@3,0" to fix this
	panic.
 - when generating fake boot paths, generate them with unit numbers
	rather than slot/offsets (thus, /obio@0,0 becomes /obio0, as
	does vmel and vmes).
 - fixed up comments to reflect these changes
tested new code on: 4/280 (diskless), 4/360 (diskless), 4/360 ("xd" disk),
	4/370 (scsi disk), ss1 w/v1 openprom (diskless),
	ss1 w/v1 openprom (scsi disk), ss2 w/v2 openprom (diskless),
	ss2 w/v2 openprom (scsi disk).

9540190d45 This file, which will be included by <sys/cdefs.h>, will contain macros 
such as __warn_references() and __weak_reference() which are actually
machine dependant.  This will make it easier for ports that are being
bootstraped with ELF and ECOFF based toolchains.

This change also introduces a new macro, _C_LABEL(x).  _C_LABEL expands
its argument, an identifier, to a character string of the identifier
name as it is represented in an object file.

For most ports, _C_LABEL(x) will expand to "_x", for ELF based ports
_C_LABEL(x) will expand to "x".

- fit the DDB interface.
- fix many typos.

- opcode aliases (`mov',`cmp',`set') for simple instructions.
- better template matching; current method is sloppy and is prone to spurious
