de7c200585 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.

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.

3a7bbb1acd lip service to making ISA support machine-independent. This is the first 
round: moving the drivers into a machine-independent directory.
Some drivers (e.g. fd.c) not moved because they use other pc features (e.g.
CMOS settings), and none of the non-driver files moved, because they're
still pretty much PC specific.  eventually (when other ports with ISA
busses really start using this code), more 'high-level' ISA support will
live here.

119f3ea688 Various: 
Put WDF_ERROR in the wdc_softc, to avoid gratuitously forcing non-active drives
into single-sector mode on the next transfer.  Arrange to wait for an interrupt
after wdsetctlr(); this avoids long busy-wait delays, and gets rid of the
`extra interrupt' messages (except for one immediately after autoconfig on some
machines).  Replace some uses of wdsetctlr() with simply lowering wd->sc_state;
no point in forcing this immediately.  Allow control operations to time out.
Enable the warnings for long busy-wait delays by default.  Some other minor
things not worth mentioning.

which the standard 386bsd 0.1 driver did have. This is for a piece of
code in the bad block handling. found/fixed by hpeyerl.

3322c7b691 all timeout code now calls DELAY() so the timeout delays are the same 
length on all processors. Where possible, the controller is reset if it
times out.

ed61b76822 increased the timeout inside wdcommand(). Some controllers impliment some 
commands very slowly.

2adecf84f6 1. It is now possible to build a kernel that does not have a pc0 device driver. 
2. "press any key to reboot" reads the key from the console.
3. wddump() still needs a non-blocking getc() routine (or flush)

545cc18754 This patch allows the wd device driver to tell how big the disks are on 
WD1007-derived controllers. In this example, wdc0 is a WD1007-clone,
and wdc1 is a WD1003-clone. WD1007 controllers are generally ESDI
and IDE controllers.
wdc0 at 0x1f0-0x1f7 irq 14 on isa
wd0 at wdc0 targ 0: 322MB 1224 cyl, 15 head, 36 sec <disktype>
wdc1 at 0x170-0x17f irq 7 on isa
wd2 at wdc1 targ 0: (unknown size) <disktype>

a0bcb17e60 support for making dev->id_alive be set, this is for iostat to 
find disk devices. wee bit of a kludge. sub-device attach()
routines must now return 1 for successful attach(), 0 otherwise.
Other bsd's do this too..

fbecd3e987 Once more: some changes to the ioconf.c structure. It will now handle 
devices hanging off controllers, any kind of controller.
A device on isa0 is called at probe(self), then attach(self)
A controller on isa0 is called at probe(self), then all it's children with
    defined unit numbers are initialized by calling attach(subdev); next all
    subdevices with unit ? are initialized by calling attach(sundev).
Almost all device entry points is now like the vax/sun model (intr being
the weird one)

bf6814fb30 wd driver would fail on calling wdgetctlr() for older drives and 
controllers. New behaviour is that if the standard method fails, try
to recalibrate the drive. Success means the drive exists.  patch by
