b444da72bd Skip fixup phase when system BIOS setting were perfect. 
don't write 0 to command register. (it is harmful).

9c43539f8f The VIA Technologies VT82C686A SMBus Controller claims to be a PCI/ISA 
bridge, ignore it. Should fix kern/10093 by Mark Dohring.

d5d280d015 -attach auxilary PCI buses at the 450NX chipset, 
tested by hubertf in a small configuration (1 PXB - 2 PCI buses)
-being here, remove the per-VID/DID matching code which was commented
 out for a while

cc30f00dd3 PCI I/O address fixup routine. 
When BIOS don't asign PCI I/O address space to device,
        allocate it without conflict and write to PCI configuration header.

e3c3882828 PCIBIOS_IRQS changed to PCIBIOS_IRQS_HINT. PCIBIOS_IRQS_HINT is 
used when no IRQ guess. when at least 1 PCI device configured
        correctly, unused.

0a1221cb28 Added a PCI frontend for the legacy ISA joystick driver. 
Some PCI soundcards don't seem to use the generic gameport function with
interface 0x10 used here, but have either an own BAR dedicated to this
(i.e. Sonic Vibes or ESS Solo-1) or specify their own device (see
PCI_PRODUCT_CREATIVELABS_SBJOY in sys/dev/pci/pcidevs.h).
Probably these use a similar simple sheme and adding a frontend for them would
be trivial, but I don't own any of these cards, so I didn't.

7f28924acc If we see a bogus $PIR table entry, just ignore it. The MPIIX has 
entries for the IRQs used by the IDE controller, which aren't really
PCI IRQs (they're ISA compat IRQs), and thus have link values that
don't make a lot of sense.

2026e5f71b PCI interrupt routing fixup code, from UCHIYAMA Yasushi's PCI BIOS 
patches, cleaned up and heavily reworked by me.  Basic algorithm is
the same, although the code structure is now quite different.

Main differences:
- Initialization path is totally different.
- We use the `compat router' information, if present, to determine which
  PCI ICU driver we should use.
- Fixup configuration headers on devices not on bus 0.

e345f0f17c Basic interface to the PCI BIOS and PCI Interrupt Routing table, separated 
out from UCHIYAMA Yasushi's PCI BIOS patches, and fairly heavily reworked
by me.

Main differences:
- Only use the PCI BIOS to get the config mechanism and interrupt routing
  info for now.  No need to use the BIOS for PCI config access right now,
  since the old mechanism works fine, and this keeps the code smaller.
- PCI BIOS initialization code path is much different.
- Always use the $PIR table if it exists, and only fallback to the
  PCI BIOS 2.1 GetInterruptRouting call if it's not there.

This module does not include any of the fixup code; that is coming
in separate commits.

026fbbe2db Match PCI-ISA bridges on class/subclass instead of vendor/device. 
2 reasons:
-no need to keep a list of all known parts
-there is at least 1 bridge (ACC micro 2051) which reports the same
 device ID for its various subfunctions; this would require an additional
 check in the match function
(keep the old list inside #if 0 in case one of the historical bridges
doesn't report the right class/subclass - I can't check them all)
