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".

23da20014a Set clock prescale based on BIOS supplied value instead of trying to
calculate an optimum value from (constant) parameters.
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").

9b2b0822b7 Removed unused #includes of <i386/isa/icu.h> and <i386/isa/icu.h>. icu.h
is only used by the icu support modules and by a few drivers that know
too much about the icu (most only use it to convert `n' to `IRQn').  isa.h
is only used by ioconf.c and by a few drivers that know too much about
isa addresses (a few have to, because config is deficient).

1608c58429 Let the user know what errors are experienced on received packets.
I spent the better part of a day trying to figure out why my
experiment didn't work the way I expected, only to find out that
the router was dropping huge numbers of packets because of PCI bus
priblems.  This does not fix the bug that errors are counted as
input packets because my patch doesn't apply cleanly.

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!

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

it was unnoticed until today.
