230847098b Some cleanup and a fix for an assumed chip bug:
- Do not malloc SCRIPTS memory for those parts of the microcode that
  are to be loaded into the on-chip SRAM of the 53c825a or 875 ...
- Modify ncr_chip_lookup to make adding new entries easier.
- Disable use of on-chip SRAM for the 53c825 rev 0x10 to 0x12, since
  there seems to be a problem with rev 0x11, while 0x13 is known to
  work. (Tested by Chuck Robey <chuckr@glue.umd.edu>).

This code will be merged into 2.2-stable after a few more days of
testing in -current.

9744aa88bd Add device IDs for new Symbios SCSI chips (53c875J,885,895,896), which
should work with no driver changes, though not all features are currently
used.

Remove code that was conditional on NEW_SCSICONF not being defined. This
was temporary code, that at a time got excluded correctly, until the new
scsiconf became the default, and NEW_SCSICONF was no longer specified.

Add support for quirks defined in scsiconf.c. For now only the HP3724/5
needs an entry, since that drive can't be used with tags.

7f10528533 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.

3c81694426 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.

89c1d5dcd9 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)

0b3870cb60 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.

e6f6908163 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.

20bc4c3ac1 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.

23da20014a Set clock prescale based on BIOS supplied value instead of trying to
calculate an optimum value from (constant) parameters.
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.

d8a8289c5a Send out a period of "0" if negotiating asynchronous transfers (offset = 0).
A value of "255" used to be sent, and though it should not matter, there

ede8dc43a2 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.

078d5aeeed 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
It is intended for use in install kernels.
