b3ac88f13f New vx driver for:
3COM 3C590 Etherlink III PCI,
        3COM 3C595 Fast Etherlink PCI,
        3COM 3C592 Etherlink III EISA,
        3COM 3C590 Fast Etherlink EISA,
        3COM 3C900 Etherlink XL PCI and
        3COM 3C905 Fast Etherlink XL PCI.

This driver is based on OpenBSD's driver. I modified it to run under FreeBSd
and made it actually work usefully.
Afterwards, nao@tom-yam.or.jp (HAMADA Naoki) added EISA support as well as
early support for 3C900 Etherlink XL PCI and 3C905 Fast Etherlink XL PCI.
He also split up the driver in a bus independant and bus dependant parts.

Especially the 3c59X support should be pretty stable now.

b36b7d853f Add basic support for the 398X cards as multi-channel SCSI host adapters.
This involves expanding the support of the SEEPROM routines to deal with
the larger SEEPROMs on these cards and providing a mechanism to share
SCB arrays between multiple controllers.

Most of the 398X support came from Dan Eischer.

10e966fae4 Add support for ioctl() accesses to PCI config space registers.
Garrett Wollman sent me this code a few weeks ago for review, and I made
some significant changes, which he in turn accepted ...

In order to make use of these changes, a device entry has to added to /dev.

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"

7fa8a688aa Add preliminary support for the Orion PCI chip set. It is special in the
way it attaches multiple PCI buses directly to the CPU, instead of having
them hanging off from PCI to PCI bridges. This code is a hack, and will
be obsoleted by the planned rework of the PCI code, which will change the
dealing with PCI to PCI bridges and other special devices significantly.

The patch also adds a kern_devconf entry for PCI bus 0 which is assumed
to be a child of cpu0. The new PCI code will make it possible to hand out
the kern_devconf structure to a pci device being attached, since this is
(regretably, IMHO) required by a few ISA devices.

Finally there are new PCI ids for some Intel chip set devices, which had
already been known to 2.1.5R, but did not make it into -current. This closes
"kern/1558: PCI probe seems to have lost a device in -current".

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.

c268c94f6b FINALLY: PCI support for the Lance Ethernet driver.
This code applies to several systems with integrated Ethernet
chip, for example from HP or Compaq. It should also support
PCI Ethernet cards based on the AMD PCI Lance chip.

This code has been reviewed (visually) by Paul Richards and
tested (using an ISA Lance board) by Joerg Wunsch.
Since the parameters to nearly each and every single function
had to be changed (generally from unit number to lnc_soft*),
there is some potential for buglets having crept in ...

BEWARE: If you had lnc0 configured to have the ISA probe find
your PCI Lance, then it should now be found by the PCI probe,
and should be automatically configured as pci1 (!!! note the "1").

33cb7dbb53 The aic78X0 cards have 0xff in all bytes of scratch ram after POST. If
a BIOS was not installed, this will still be true by the time we probe
the chip.  We use this heuristic to determine if we should use the left
over scratch ram target settings for controllers that don't have an
SEEPROM.  We also "snapshot" the host adapter SCSI id and whether ultra
is enabled or not and use these values if a BIOS was installed.  The card
will act as if a BIOS was installed even if there wasn't one if you warm
reboot, but since the scratch ram area is still valid in this case, its
hardly worth the effort of writing a shutdown routing that clears out
the scratch ram.  This should make users of motherboard controllers
happy.

7e1f0d8dc5 Be more careful in how we set SCSICONF. It was possible for a controller
set to a device id above 7 to screw up the data fifo setting.

100eb37c65 aic7870.c, ncr.c:
Cleanse the SCSI subsystem of its internally defined types
	u_int32, u_int16, u_int8, int32, int16, int8.
	Use the system defined *_t types instead.

aic7870.c:
	Handle Seeprom data a little better.

6380fb9d12 Hopefully, this will fix the problems that some people have been having with
the S-Video input.  It also has code in the driver for the meteor RGB support
and some other bug fixes.  I don't have a meteor RGB but I have been told
that it works.

8ec7a852b0 Remove limit of port I/O addresses to 65K, since PCI specifies 32 bit
port addresses (even though the PC architecture doesn't support them).

Add code to limit the I/O map size based on the lowest set bit of the
address. This cures the problem with the BT946C only having a 16 bit
map register, in voiolation of the PCI specs, without giving up the
general support of >65K port regions.

9b44ff2214 Clean up Ethernet drivers:
- fill in and use ifp->if_softc
	- use if_bpf rather than private cookie variables
	- change bpf interface to take advantage of this
	- call ether_ifattach() directly from Ethernet drivers
	- delete kludge in if_attach() that did this indirectly

218d60ad3d Slight modification of ncr_setmaxtags: set usrtags=0 for drives
that don't announce support for command queues.

SCSI_NCR_DFLT_TAGS can be specified in the kernel config file
and sets the default number of tags per disk drive.
A value of 0 means "no tags".

Minor correction in debug messages: Values from the msg_in
buffer were being printed in the msg_out trace message ...

dcf289cdb5 Add heuristic to detect multi-function devices that don't announce this
feature in the header type register, though it is required by the PCI spec.
This should correctly probe both functions of the Intel 82371FB chip,
without the need for a special case based on the device ID.

5dec5a0060 Implement a prototype interface to bus-master IDE DMA on the Triton
chipset.  This does not attempt to do anything special with the timing
on the hope that the BIOS will have done the right thing already.  The
actual interface from the wd driver to the new facility is not
implemented yet (this commit being an attempt at prodding someone else
to do it because looking at the wd driver always confuses the h*** out of me).
