History
mycroft f9d629fb93 Fix more probe delay and/or failure problems: 
1) Don't wait for DRQ on an IDENTIFY command -- if it's not set when we see
   BSY clear, abort the command and ignore the drive.  (Do this by testing
   for DRQ in the read/write cases in __wdccommand_intr().)
2) Don't wait for DRQ to deassert when we finish an IDENTIFY (or any other
   non-block command that reads data) -- we don't do this for block I/O, and
   empirically it doesn't clear on my CF cards at all, causing a pointless 1s
   delay.
3) Add comments to some of the delay()s, and add missing ones in wdcreset()
   and the WDCC_RECAL in the so-called "pre-ATA" probe.
4) Slightly simplify the reset sequence -- we were doing an extra I/O.
5) Modify the register writability test to make sure that registers are not
   overlapped -- this can happen in some weird cases with a missing device 1.
6) Check the error register value after the reset -- if it's not 01h or 81h,
   as appropriate (see ATA spec), punt.
Tested with a number of ATA-only, ATAPI-only, mixed ATA-ATAPI, CF, and IDE
disk configurations.

Also remove the SINGLE_DRIVE nonsense again.

This directory contains files which are used during PCI configuration
and PCI device drivers.  Eventually, most of the device drivers and
some of the configuration support should become machine-independent
and be moved to a more general location.

The configuration support was implemented according to the `PCI Local
Bus Specification, Production Version, Revision 2.0' dated April 30,
1993.  Section numbers referred to in the code may be specific to that
edition of the specification.

Some attempt has been made to insure that the code works on rogue
machines where the BIOS doesn't do its job, but in general I can't
guarantee that.
