0d12199628 It seems that the aic78X0 chips will either have their scratch ram
as all 0s or all 1s after POST if there is no BIOS installed.

8408422768 Add support for NE2000 compatible PCI Ethernet cards. The PCI probe
is enabled by having an "device ed0 at isa? [...]" config line.
The first PCI card will get a unit number one higher than the highest
defined for any ISA card of the ED type, e.g. if ed0 and ed1 are
configured, then the PCI cards will be ed2, ed3, ...

BEWARE: If you have configured your kernel as ed0 with the port address
as assigned by the PCI BIOS, then your card will be found by both the
PCI and ISA probes, and bad things may happen. Make sure to restore
the original port address form the GENERIC kernel for the ed0 device!

58efe44318 Fix a brain-o. The scratch ram on aic78X0 controllers is initialized to 0x00
not 0xff after POST, so test for that when trying to determine if a BIOS
intialized the card for us.

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.

f8176d838c Fix logic bug in pci bridge code. For a PCI-PCI bridge, secondary
should be <= than subordinate, not the other way around.

They are both true if the bridge is not cascaded (i.e., twin-channel
scsi/e-net adapters won't be affected by this bug), which is probably why
it was unnoticed until today.

68159c8901 Update PCI bus code from my current sources:
- always use pci_conf_read() and pci_conf_write(). (This is required to
  simulate non-existant devices in my system for PCI bridge code tests.)

- reorder some functions (put the main functions at the end).

- correct off by one bug in the code dealing with unitialized PCI to PCI
  bridge chips. (Bug found by ASAMI Satoshi.)

- print function number for multi-function devices.

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.

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.

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.
