bouyer 47ab212504 Rename pio_mode, etc ... to PIO_cap, etc ... for consistency with the
ata_drive_datas struct. Suggested by Soren S. Jorvan.

bouyer 2b28c858d8 add a udma_mode field to wdc_softc, and use it the same way dma_mode is used
(higthest ultra-dma mode supported). There may be a higther ultra-dma mode
defined ...

bouyer 1d5d5ab40a In struct wdc_xfer, change 'channel' to a pointer to a channel_softc, to avoid
a double-pointer dereference at run-time. Suggested by Matthias Drochner.

drochner 3e38051bc5 in wdc_softc: access the per-channel data via a pointer array instead of
an array of fixed-sized channel_softc elements. This way IDE controllers
which more than 1 channel (pciide) can extend the channel data easily
for private needs.
To avoid the double dereference at runtime, change the argument of
wdcstart() to the channel data pointer instead of the array index.

mark 962edcdc03 Add data32iot and data32ioh members to the wdc_attachment_data structure.
This bus space tag and handle is used for 32 bit data transfers i.e.
when WDC_CAPABILITY_DATA32 is enabled as the 32 bit data register may
not be part of the standard drive registers.

kenh 9539399333 Add support for passing device quirks from the attachment routine,
and add support for a NO_EXTRA_RESETS quirk (required by the TEAC
IDE Card/II, which the Vaio uses).

leo fe60e74148 Add hooks to make exclusive hardware locking possible. This is necessary
to make the driver suitable for the atari falcon.

cgd 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.
