0f764f43a1 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).

691b2156f8 For the sake of people, who like to move pci_configure()

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 ...

4b08898037 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
problem has been seen only with very few devices.

57e383cd4c 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.

83418166e2 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.

Bug fixed, that caused system hang on first interrupt on some motherboards.

New version of PCI bus configuration code, now supports dynamic interrupt
configuration (using BIOS supplied values).
NCR SCSI and DEC Ethernet driver patched to use this feature.
