mycroft 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.

bouyer 7ba46a56e0 Correct defifintion of the WDCE_MCR and WDCE_ABRT bits: they have been
inverted since the begining.
This doesn't change anything, as these bits are not used in the driver.

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.

bouyer 6f3bab1f59 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.

mycroft db3bde9525 Implement EIDE multi-sector PIO and DMA modes, based on code from Onno van
der Linden.  Also, various structural cleanup, and fix two bogons that crept
in, and remove all of the old clustering nonsense.

mycroft e1a7bac628 Change some constant names, etc., to better match the ATA spec. 1994-11-22 05:34:49 +00:00
mycroft 4ec6774e12 Add a simplified version of wdcommand() that can be used in some cases.
Avoid needing a wd_softc inside wdprobe().
