Overhaul of the ISA autoconfiguration code to support direct
configuration of devices logically attached to the ISA bus:

* Change the isa_attach_args to have arrays of io, mem, irq, drq
resources.
* Add a "pnpnames" and a linked list of "pnpcompatnames" to the
isa_attach_args. If either of these members are non-NULL,
direct configuration of the bus is being performed. Add an
ISA_DIRECT_CONFIG() macro to test for this.
* Drivers are not allowed to modify the isa_attach_args unless
direct configuration is not being performed and the probe fucntion
is returning success.
* Adapt device drivers -- currently, all driver probe routines return
"no match" if ISA_DIRECT_CONFIG() evaluates to true.

Merge scsipi branch in the mainline. This add support for ATAPI devices
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.

branches: 1.5.8; 1.5.10;
New bus.h implementation/interface:
- No more distinction between i/o-mapped and memory-mapped
devices. It's all "bus space" now, and space tags
differentiate the space with finer grain than the
bus chipset tag.
- Add memory barrier methods.
- Implement space alloc/free methods.
- Implement region read/write methods (like memcpy to/from
bus space).
This interface provides a better abstraction for dealing with
machine-independent chipset drivers.

Handle BUS FREE phase a little differently, to get better error detection. Other
cleanup.

Disable debugging breakpoints by default.

* Redo most of the message and phase state machines. Multiple pending
message outs should now work correctly (including retransmissions).
Multiple messages ins should be more efficient. Missing REQ after
reselection phase should now (correctly) cause a wait with ENREQINIT
set.

* Abstract out the reselection out sequence, and use it directly to
get sense info. (This is somewhat faster than the generic done/sched
sequence.)

* If there are no ACBs available, wait interruptibly for one.

* Leave the interrupt registers alone during message in/out; just
watch for phase change. Don't (incorrectly) reenable interrupts
during data in/out; defer that to aicintr().

* Handle command pointer per SCSI 2 spec.

* Other minor coding improvements.

New interrupt code. The basic idea behind it is to hide the differences
in interrupt controllers in struct pic, and try to keep as much
common code as possible. At the lowest (asm) level, this is done
with CPP macros.

The main structure is now struct intrsource, describing an established
interrupt line, of any kind (soft/hard local apic/legacy apic/IO apic).
For quick masking, there may be a maximum of 32 sources per CPU.
Sources can be assigned to any CPU in the MP case, though currently they
all go to the boot CPU.

Recalculate delaytab[]. We need to round up in case we were on the edge of a

up being 1 tick short. An unlikely event, but just in case anything actually
relies on this...

rtclock_tval as the limit, since this is what we actually programmed the chip
for.

noise reduction.

use mi data conversion functions, simplify inittodr() and resettodr()

put all century related code into an own function clock_expandyear(),
touch the CMOS century byte only if the CMOS contents passes a
checksum test which qualifies it as "known compliant"

Be more cautious about writing to the CMOS century byte. Update it only
if it contained a "19" before. There are machines (in particular PS/2
descendants) which have a checksum at this place.
Introduce a patchable kernel variable "rtc_update_century" to modify
the behaviour: 1="always update" (for testing and if one wants to set
the clock back) or -1="never touch".

Fix a stupid bug -- an if that was supposed to be nested but wasn't.

1) Change "dectohexdec" and "hexdectodec" to "bintobcd" and
"bcdtobin". The old names were bogus.
2) Make the code grok the NVRAM's century field. This code is, to say
the least, poorly tested. It should make NetBSD play nicer with other
OSes that care about the century field, however.

Fix a potential Y2K bug on some clock chips: we were loading invalid
BCD into the year field of the RTC in years > 1999. It seems to have
worked just fine on my old broken down test machine, but apparently
some others actually get hurt. Suckage. We now make sure that we load
valid BCD.

Other ports should check for variations on this theme.

bzero->memset, bcopy->memcpy

Fix a problem first noticed by a user with a screwed up real time
clock past the End of Time.

If time_t is 32 bits, then the "End of Time" is Jan 18/19 2038
(depending on time zone).

This code copes with RTC's past the end of time if time_t is an int32
or less. It just forces the time back to 2037. This will let users
with screwed up clocks to at least boot and function long enough to
set their clocks to something sane.

This kludge is conditioned on an
if (sizeof(time_t) <= sizeof(int32_t))
which will automatically optimize the code out once we switch time_t
to a 64 bit quantity, which should happen well before 2037.

warn user and user base time. if base time < 1985, warn the user.

Add floppy formatting facility.
i386 floppy controller code came from FreeBSD, as worked on by:
jc@irbs.UUCP (John Capo)
vak@zebub.msk.su (Serge Vakulenko)
ache@astral.msk.su (Andrew A. Chernov)
joerg_wunsch@uriah.sax.de (Joerg Wunsch)
dufault@hda.com (Peter Dufault)

formatting ioctl interface is generalized to an MI interface. see fdc(4)
and fdformat(1)

In fdcresult(), the loop that pulls status off the controller is treated
as a "timeout", yet there's no specific delay in each iteration. Add
a small delay (10 usec... pretty arbitrary) in each iteration. This
fixes the "fdcresult: timeout" problems I've been having on my 200MHz P6.

Use bitmask_snprintf().

New bus.h implementation/interface:
- No more distinction between i/o-mapped and memory-mapped
devices. It's all "bus space" now, and space tags
differentiate the space with finer grain than the
bus chipset tag.
- Add memory barrier methods.
- Implement space alloc/free methods.
- Implement region read/write methods (like memcpy to/from
bus space).
This interface provides a better abstraction for dealing with
machine-independent chipset drivers.

New device attachment scheme:

- split softc size and match/attach out from cfdriver into
a new struct cfattach.

- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.

Update for changed DMA interface.

In fdcretry(), set the state to DOSEEK rather than SEEKCOMPLETE before
retrying the operation. Fixes disk_unbusy() imbalance and really seems
like the right thing to do in case it was the seek that failed. Takes
care of PR #1985. Patch from John F. Woods <jfw@jfwhome.funhouse.com>

Balance calls to disk_busy() and disk_unbusy() properly to avoid
dk_busy < 0 panics. Count seeks.

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.

fixed my own pr 1758 -- the floppy drive motor was not being turned off
at halt time, especially if a floppy was mounted. Added a shutdown hook
to turn off the motor. Per a request by mycroft, the cookie from the hook
is saved in a new member I added to the fd_softc structure.
