7299c7a6c0 Have v[un]mapbuf() allocate from plain kernel map instead of dvma space. 
Remove dvma_malloc/dvma_free; drivers should allocate kernel memory and
use dvma_mapin/dvma_mapout to double map it in DVMA space.

Make the resource map `dvmamap' responsible for all DVMA allocation.
The VM map `physmap' only serves the role of placeholder in the VM system.

9c784e07c1 Fix the integer overflow problem in pmap_init() when the user PT map is 
allocated, as noticed by Chuck Cranor.  In addition to re-arranging
the assignment as suggested by Niklas Hallqvist, check to see if maxproc
is higher than the number of available user PTs.  If it is, lower maxproc
to that value, the rationale being that it's much more desirable to have
fork() return EAGAIN than to have your system wedge.

XXX note that root can still raise maxproc with sysctl(2) later.  It's
probably worth having further discussion about this issue, but until
everyone has time to think about it, this seems like an acceptable solution
for the time being.

deb00c27b3 Use a "match/attach" rather than "init" scheme for probing devices. 
This is a step towards getting the drivers ready for new config.

Clean up namespace, remove several instances of global arrays.  Instead,
use a softc to carry state around.  Where possible, pass a pointer to
the softc rather than a unit number.

Pointers to hardware and software constructs are now stored per port
in each instance of the softc (one softc per board) rather than indexed
by minor number.

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.
- do synch negotiation (now that the above works).

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).

d0e01feb5c Do an indirect driver a little more like an indirect driver would like to

controller-specific probe routines, and jump through them, instead of
if()'ing our way though each operation.

Be a little more discriptive; print out the controller type found
during the probe in a way that's somewhat meaningful.

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.

These now compile, but have not been tested.

93d0f65970 New SCSI driver for the NCR5380, by David Jones. 
Does DMA with interrupts.  Much faster than our old
driver which did only PIO transfers. (Thanks David!)
Could be used on the amiga, and probably others...

e4fcc8ab5a Move DMA chip draining to dmaintr() and drain when a (possibly partial) 
transfer ends in stead of doing it before starting a new transfer.
Use a different CSR bit to wait for "chip not busy" (may be necessary to
make this conditional on chip revision).

a3f2bf19e4 Various: 
- make esp_poll() approximate the given timeout value.
	- introduce esp_abort(), and use it for timed out commands; make		  targets and driver less confused.
	- make {free,ready,nexus}-list management somewhat more coherent.
	- make sure we only proceed down the state machine in espintr()
	  if there really is an interrupt pending.
