a1471db64a move wd.c:print_wderror() to ata.c:ata_perror(). 
In wdc_probe_caps() add code to guess the ATA revision supported (if
ATA4 if Ultra-DMA, ATA2 if PIO mode > 2). We can't rely on param.atap_ata_major
here, at last one Ultra-DMA drive claims to support only ATA-3.
Use the ATA version in ata_perror(), and to try a flush cache command
in a shutdown hook for IDE drives.

48f2e0ae6c Add a new flag to wdc_command: ATA_READREG. This will indicate that all 
device registers should be read back into the wdc_command structure after

7bdbb5c993 Donc reset the disk state to 0 in wd.c, set a flag which will cause it 
to be reset to 0 at wdcstart(). This fixes a race condition between
normal I/O and wdioclt(). Also use interrupts for wd_get_params in wdopen().

eddaea2d53 In LBA mode, always use the `total capacity' count, rather than calculating 
the capacity based on the c/h/s numbers.  In fact, don't use the c/h/s
numbers for much of anything.
For ATA-4 drives or later, always use LBA mode, since it's now required.

Collectively, this allows >8GB disks (like the 12GB Bigfoot) to work.

68096acabd From Robert V. Baron: 
Compute the disk block addr at command queing time rather than exec time.
This fix a bug which could lead to data corruption on disk: when a command
was reexecuted after an error condition (from wdcunwedge), the partition
offset was re-added to the block addr, leading to a transfert at the wrong
disk block.
This should fix the problem reported by some laptop's users, where the
first disk read after a suspend/resume returned garbage.

aaede4d8d8 Various cleanups and bug fixes to the wdc/wd code: 
* Fix bug in wdc that would overflow ATAPI transfer length.
* Improve wdc probe code so that 'wdc' is probed in if present
  even if there are no drives attached, and so that it works
  properly even if the only device is an ATAPI slave.
* bus_space-ify.
* split the ISA attachment from the wdc driver, and remove
  ISA dependencies from non-ISA files.
* claim that wd and wdc are now machine-independent (probably not
  completely true, but mostly so; they at least work on arm32 and
  i386).
* Various other minor fixups and cleanups, some of which were pointed
  out by Kazuki Sakamoto.

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.

and structure elements around.  kill some unnecessary type and macro
definitions.  standardize clock handling.  More changes than you'd want.

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.
