7ccde0654a Re-enable conf82371fb2 now that I have verified that it works, even if
it only prints 2 bits out of hundreds.  (Minimizing the diff between
-head and 2.1.5.)

c6060a60ef Fix Orion specific code by moving config_orion() to a place where it does
not depend on bootverbose being true.

Include only register specifications for those chip sets that apply to
a cpu that might boot this a particular kernel (ie. make the Saturn code
depend on I486_CPU being defined, the Pentium chip sets on I586_CPU ...)

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".

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).

31c5632840 Decode configuration for the IDE part of the Triton chipset. This
includes a hack in the probe code: the 82371FB is a multifuction
device, but doesn't properly set the configuration bit which
indicates this.  So, we just hard-wire all 82371FBs as multifunction
devices.

This does not actually make the bus-master IDE stuff work, although
if anyone wants to work on that, I have the databooks that tell
how to use it.

8673e05a9a Completely new PCI code:
1) Supports PCI to PCI bridge devices (and tries to initialise them,
   even if the BIOS is brain dead).
2) Supports shared PCI interrupts. Interrupt handlers now MUST return
   '0' if they found nothing to do, '1' otherwise.

New features tested with i486 systems based on the Intel Saturn and
a DEC 4channel Ethernet card only, but expected to work on most systems.

The option PCI_REMAP has been removed !

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.

c79b89e28f Add code to deal with PCI-PCI bridge chips, especially the DEC 21050.
Try to deduce maximum number of PCI buses in system (working around
chip set bugs).
Better check for devices at multiple addresses (aliases).
