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.

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).

Files moved here from sys/i386/pci, since they are meant to be
architecture independent.
