8a5504241e Three distinct changes: 
- Better disklabel handling.  While a disklabel isn't used
	  in the driver, some versions of the OpenPROM insist on
	  one being present in order to boot from floppy.  These
	  changes provide a default label (in a way similar to how
	  the SCSI disk driver provides a default) so that a user
	  can more easily place the label on the disk.

	- Fix semi-bug in bootpath handling.  It appears as if the
	  bootpath can appear in a couple of formats: "/fd@0,0", which
	  is what bootpath_fake() creates on v0 proms and may be
	  passed by some v2 proms, and "/fd0" which is what the
	  v2 prom on my SS2 passes.  We now handle both formats.

	- Use a mountroot hook to eject the floppy and wait for
	  the user to insert a filesystem floppy if we're the boot/root
	  device.

ef895a47d4 - call mapiodev() with sizeof(struct xyc) rather than ra_len (which is 
zero since xycmatch no longer sets it).   [if you call mapiodev()
	with a zero size it will reuse the KVA it returns, swiping the device
	out from under you!]
 - make xyc->iopbase point in the kernels DVMA space rather than at the
	normal malloc'd KVA.   this isn't compatable with sun4m [doesn't
	have a kernel DVMA space] and will need to be changed later (XXX).
 - move disk_attach() to before reading the disk label as per Jason.
	otherwise we are reading into an unallocated buffer (oops!)

b5ddd8431d dmamatch never added in the offset for the dma registers to the VA, 
and thus probed the wrong address on the 4/300 (but it worked because
it was probing the esp0 registers!).

now that bus_tmp() adds the offset in for us [as of obio 1.19] i
discoved that a byte access to the dma registers is not allowed.
so, i've change probeget to use a word access.

afb262e8da improved handling of mapping of devices who's registers do not reside on 
page boundaries:
 - change bus_tmp() to include the offset from the start of page in the
        returned KVA [rather than forcing each driver to add it back in
        individually]
 - changed bus_map() to include the offset from the start of page in the
        the returned value if a mapping is found in the PROM's KVA area
 - clarified a few comments

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

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.

- deal with MSG_OUT phase better
- keep some "config reg 3" bits per target (ie. FASTCLK and FASTSCSI).

b3ecc4c310 make sure devopen() sets pd->devtype properly when BOOTXX is defined 
(should be DT_BLOCK).  otherwise the bootxx boot block will fail if
you are on a system with a v2 openprom [because it will not do the
v2_seek in obp_strategy()].    fixes the problem recently noted on
the port-sparc list by matthew green <mrg@eterna.com.au>.   i tested
fix on a ss2 with a v2 prom.

		(xdgetdisklabel() now returns if label was ok or not).

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),
