CNB20LE.

8002eb91a6 -fix botched switch/case nesting which made AGP on i810 in GFX mode fail 
-remove the check for i810's internal graphics completely: we'll attach
 AGP whether in GFX or AGP mode anyway, and the SMRAM register test
 was of questionable value (should have masked with 0xc0, but even then
 the builtin graphics appeared enabled although I used an external
 PCI card)

43bbb8500a Apparently some ServerWorks Host-PCI bridges only get their memory space 
enabled, even though IO space does work. A few drivers (like ahc)
will only work reliably with IO space, so check for this condition
and correct it.

2c8172cbd3 Attach agp gart support @ pchb. Not very clean, but agp support may 
be spread over several devices, and the phcb is usually the main one.

Add agp_machdep.c file which implements MD agp functions (currently
just agp_flush_cache).

3d193b190b - Pequr -> Serverworks. It pays to do a cvs update first... 
- Pay attention only to the low byte of config reg 0x44 on Serverworks chips,
  as Linux does.
- Compress duplicatated code.

for NetBSD by me.

2644e830b7 BIOS BUG WORKAROUND! The 82443BX datasheet indicates that the only legal 
setting for the "Idle/Pipeline DRAM Leadoff Timing (IPLDT)" parameter
(bits 9:8) is 01.  Unfortunately, some BIOSs do not set these bits properly.

Based on a hint from OpenBSD.

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

30612943e3 Implement a simple generic PCI-Host bridge driver. At the moment, this 
driver is a place-holder, which will nicely print version information
about your PCI chipset (try with "options PCIVERBOSE").  Eventually,
this can be used to enable/disable features/bugs of individual PCI
chipsets.
