d36d3f0e18 Print more information in case of unspecific error condition. 
Do not print "in getcc reselect by" message unless DEBUG_RESTART is set.

d54b39155a Return an extended status of XS_TIMEOUT (instead of XS_DRIVER_STUFFUP) 
in case of an unspecific error (most likely software timeout after
SCSI bus reset).
This will make the generic SCSI code retry the failed command.

57da02d3f3 Changes to support some CDROM drives and the Quantum Grand-Prix 
series of hard disk drives, which don't accept any SCSI message
within an REQUEST SENSE command (i.e. even not an IDENTIFY to set
the LUN).
This patch obviates the need for QUIRK_NOMSG and thus all of the
device_tab[] entries in the NCR driver.

cb09d35cb0 Added a new field to the pci_device struct called pd_shutdown to specify 
a device specific shutdown routine for devconf. Assign the value of this
to the kern_devconf struct. Implement a device shutdown routine for if_de
that disables the device. This will stop the device from corrupting memory
after a reboot.

252e349211 Reduce burst length to 4 DWORDs for now, since there seem to 
be 486 chip sets that can't tolerate bursts > cache line size.
This should really made dependent on the particular buggy
chip sets, but for now we'll play safe ...

3453c5d5db Improve diagnostics: 
Test for correct execution of cache test script by NCR,
and give meaningful error description if it fails.
(A cache problem was reported before.)
Don't wait forever for cache test to complete (to protect
against faulty hardware).

9ddf96998e ncr.c: 
New config option "NCR_IOMAPPED" makes the driver use port I/O.
Put back in 53c815 defines, submitted by Mikael Hybsch <micke@dynas.se>.
These had got lost between cvs rev. 1.14 and now ...

pci.c:

Really write config space register.
Assign ports starting at 0xbc00.

ea6ecb4e52 Disable disconnect after drive timeouts, since these 
may be the result of reselect following too fast for
the driver to notice. Not the final solution, but the

6398cf3113 Reapplied all of Stefan's changes. What a mess - the files were modified 
and moved at the same time. This made it *very* difficult to fix the
revision log lossage that happend when the files were moved. SIGH.

99e7cabca3 Really deactivated the code that puts scsi stats into dk0. 
This should have been disabled for some time, but I had screwed up ...
This made spurious values appear for fd0 in systat, when there was
NCR SCSI activity.
