c411726b79 Change message "not supported" to "no driver assigned", because
people tend to assume their devices won't work if they see this
message, though it may indicate that those devices just don't
need any PCI driver (e.g. devices that emulate an ISA card, or
that have been initialised by the BIOS and need no further care).

78e444665c Failure of the consistency checks for BIOS assigned mappings of busses
connected via PCI to PCI bridges is considered non fatal for now.

cbb15d7c97 bzero the malloced pci_devconf structure. This should fix the problem with
several of freefall's recent crashes.

f0d47944e2 Forward-declare kern_devconf for use in a prototype. Some drivers
include <pci/pcivar.h> without including <sys/devconf.h> and other
drivers include <pci/pcivar.h> before including <sys/devconf.h> if
certain identifiers are defined.

The devconf headers have convoluted interdependencies.  <sys/devconf.h>
includes <machine/devconf.h> which includes <pci/pcivar.h>.  Most
drivers include <sys/devconf.h> so even isa drivers depend on
<pci/pcivar.h>.  For similar reasons, most drivers depend on another
pci header, on an isa header and on two scsi headers.

a54907a1a7 Restore my changes to initialize the kdc_shutdown routine pointer. Stefan
clobbered it in his previous commit and not having it causes the machine
to panic during reboot (as well as not doing the important shutdown callout).

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.

04dbb40865 First try to add support for PCI-PCI bridge chips (written for the
DEC 21050 chip in particular, don't have specs of other such chips).

This should add support for Multiple-Ethernet PCI cards (e.g. Znyx 314).

d9dc2f74ef New PCI attach code:
PCI BIOS mappings are retained, except if option PCI_REMAP
is specified in the kernel config file.
There is now a list of attach addresses, and the first
address that seems to make some device registers appear
is chosen.

6398cf3113 Reapplied all of Stefan's changes. What a mess - the files were modified
and moved at the same time. This made it *very* difficult to fix the
revision log lossage that happend when the files were moved. SIGH.

Bug fixed, that caused system hang on first interrupt on some motherboards.

New version of PCI bus configuration code, now supports dynamic interrupt
configuration (using BIOS supplied values).
NCR SCSI and DEC Ethernet driver patched to use this feature.

f86233fe54 Added a bit of missing functionality to make this work correctly on a
wider variety of systems.  Include the deivers from pci_intel.c in
pci_config.c (I hope this is what was intended; my system works ok).
Use pmap_mapdev().  Automatically map any large linear frame buffers
or whatnot in VGA-style devices which ordinarily would not have their
own drivers, and don't call not_supported() for them.  (This shuts up
complaints about my Matrox card.)  Include the beginnings of what could
eventually become dynamically-loadable PCI devices.  Allow for the
possibility of PCI devices simply providing a PCI veneer over an existing
ISA device, and shut up about them, too.
Make autoconfiguration text conform more to the style of other supported
buses.
