f477b66143 Fixed the type of timeout functions and removed casts that hid the
type mismatches.  There was no problem in practice (at least on 386's).

Removed NetBSD-related TIMEOUT macro.  NetBSD uses the same BSD4.4Lite
timeout interface as FreeBSD.  As a concession to portability, declare
the timeout function without using the FreeBSD timeout_t typedef.

0bc1781701 Fixed some invalid (non-atomic) accesses to `time', mostly ones of the
form `tv = time'.  Use a new function gettime().  The current version
just forces atomicicity without fixing precision or efficiency bugs.
Simplified some related valid accesses by using the central function.

808a36ef65 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

9c95df7455 Fix NetBSD pr kern/3067, which also applies to FreeBSD:
NCR driver dies when "xmcd" accesses the CD-ROM drive

Restrict cacheing of INQUIRY results to LUN 0.

Thanks to Dave Huang <khym@bga.com> for reporting the problem
and suggesting a fix, though I chose a slightly different one.

0d930771c9 General cleanup and new features for 53c875 based cards, especially the
Tekram DC390W/U/F, whose config EEPROM can now be dumped, if the kernel
is built with option NCR_TEKRAM_EEPROM.

Other changes:

- add brackets to expansion of OUTB/W/L macro arguments.
- remove unused NCB structure element ns_async
- support sync. SCSI offset of 16 (instead of only 8) on 825A and 875
- correctly identify 53c810A and 53c825A chips
- preserve SCSI BIOS settings of PCI performance options
- remove (already disabled) support for NCR reset because of command timeout
- reverse order of reading of SCSI and DMA specific interrupt cause registers
- add definition of Tekram config EEPROM contents (not currently used)

0e16e2c15f Close PR#2198:
I've added an installation from optical disk drive facility.
	This enables FreeBSD to be installed from an optical disk, which
	may be formatted in "super floppy" style or sliced into MSDOS-FS
	and UFS partitions.

	Note:  ncr.c should be reviewed by Stefan Esser <se@freebsd.org>
	and cd.c by Joerg Wunsch <joerg@freebsd.org> before bringing this
	into 2.2.

b006cd5501 Only access the specific interrupt status registers if required.
This follows more closely the suggestions in the latest NCR docs, and has
been running on my system for weeks with no problem. It does improve the
quality of diagnostic messages and does allow to better understand the
sequence of events in case of an error.

This should go into 2.2 and 2.1.6.

1e0af50143 Improve support of SCSI cards based on the 53c860 and 53c875.
Still no support for Ultra-SCSI and other new features, but the code
should now correctly initialize the clock pre-scaler (based on freqency
measurement results, if necessary).

Fix support of 16 targets for WIDE SCSI.

Disable bus reset in case no progress is made for too long ("ncr dead"
message), which did not work too well with scanners and other slow devices.

012c55b70a Set clock prescale based on BIOS supplied value instead of trying to

This should set the SCNTL3 register of the 53c860 and 53c875 to twice
the divider it used to be, since cards based on those chips seem to use
an 80MHz clock instead of the Clock Doubler feature and a 40MHz clock.

450b4c5cf4 Fixed unsigned longs that should have been vm_offset_t.
vm_offset_t is currently unsigned long but should probably be plain
unsigned for i386's to match the choice of minimal types to represent
for fixed-width types in Lite2.  Anyway, it shouldn't be assumed
to be unsigned long.

I only fixed the type mismatches that were detected when I changed
vm_offset_t to unsigned.  Only pointer type mismatches were detected.

99d2273f94 If FAILSAFE is defined, then:
- Do not enable tagged commands by default
- Probe only 1 LUN
- Do not negotiate sync. transfer with CDROM drives

Defining FAILSAFE will result in a driver that will tolerate
marginal hardware for the price of a slight loss of performance
