153eb46fb6 On the new Meteor cards, the Philips SAA 7116 is connected to the PCI bus
via an IBM PCI-PCI bridge (82351 or 82352 or 82353)

The driver must identify if it is on a secondary PCI bus, which is
created via the IBM PCI-PCI bridge. If it is, then it must initialise
the IBM PCI-PCI bridge correctly.

To do this, the following new functions are added.
Because they use the pcici_t tag, they are considered 2.2 compatibility APIs
  pcici_t * pci_get_parent_from_tag(pcici_t tag);
  int       pci_get_bus_from_tag(pcici_t tag);

(The _from_tag suffix is used to prevent clashes with similarly named
 newbus PCI API functions)

aa6de8e012 Add support for multiple PCI "hoses" used on various alpha platforms.
The specific intent of this commit is to pave the way for importing
Compaq XP1000 support.  These changes should not affect the i386 port.

49e5f1b929 Use the probe priority mechanism to make sure the chip* probes do not
displace a real driver.
Revert rev 1.109.
Pick up a few things from elsewhere (a couple of SiS id's).

As an *experiment*, have the chip* driver claim (for reporting purposes)
IDE controllers if there isn't another PCI-aware ide or ata driver to
grab them.  I've exported the match function since it could be used from
the ata-all.c code replacing ata_pcimatch() - but I have not touched the
ata code.  I'd like to catch a few more devices this way, including USB
and other bridges etc.

46f40af052 Replace the pcidevice_set linker set based configuration mechanism for old
style pci drivers with a simple one-line change to use a module that
registers itself under new-bus and should in theory enable just about all
of the pci drivers to be loadable (kldload and loader(8)) but without
having the impact of converting the APIs yet.

This also fixes the problem of having undefined variables when only
new-style pci drivers are present.

6182fdbda8 Bring the 'new-bus' to the i386. This extensively changes the way the
i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition.  eisa, isapnp and pccard* are
not yet using the new resource manager.  Once fully converted, all drivers
will be loadable, including PCI and ISA.

(Some other changes appear to have snuck in, including a port of Soren's
 ATA driver to the Alpha.  Soren, back this out if you need to.)

This is a checkpoint of work-in-progress, but is quite functional.

The bulk of the work was done over the last few years by Doug Rabson and
Garrett Wollman.

441e39d74a Fix problem with zero valued map registers followed by valid map entries.
The previous code just ignored the invalid map register, but this gave
surprising results because of the way pci_map_port() associated the map
register offset supplied with a map entry in the map array.

92e81ca475 Let drivers specify interrupt flags (INTR_EXCL and/or INTR_FAST)
using the new pci_map_int_right() variant of pci_map_int().  Fast
interrupts work for PCI devices if and only if they are exclusive.
(The PCI interrupt mux doesn't support fast interrupts and can't
support a mixture of fast and slow interrupts even in principle.)

Don't assume that intrmask_t == unsigned in pci_map_int().

35f069d08b pci_device pd_probe function changed from returning char * to returning
const char *.  Originally I was going to add casts from const char * to
    char * in some of the pci device drivers, but the reality is that the
    pci device probes return constant quoted strings.

df9efa9a8b On the alpha, ports may be allocated above 64k.
Change the port address argument to pci_map_port to pci_port_t* which is
defined as u_int on the alpha, u_short on i386.  This is a stopgap with a
hopefully limited lifetime.

5bec615793 Completely replace the PCI bus driver code to make it better reflect
reality. There will be a new call interface, but for now the file
pci_compat.c (which is to be deleted, after all drivers are converted)
provides an emulation of the old PCI bus driver functions. The only
change that might be visible to drivers is, that the type pcici_t
(which had been meant to be just a handle, whose exact definition
should not be relied on), has been converted into a pcicfgregs* .

The Tekram AMD SCSI driver bogusly relied on the definition of pcici_t
and has been converted to just call the PCI drivers functions to access
configuration space register, instead of inventing its own ...

This code is by no means complete, but assumed to be fully operational,
and brings the official code base more in line with my development code.

A new generic device descriptor data type has to be agreed on. The PCI
code will then use that data type to provide new functionality:

1) userconfig support
2) "wired" PCI devices
3) conflicts checking against ISA/EISA
4) maps will depend on the command register enable bits
5) PCI to Anything bridges can be defined as devices,
   and are probed like any "standard" PCI device.

The following features are currently missing, but will be added back,
soon:

1) unknown device probe message
2) suppression of "mirrored" devices caused by ancient, broken chip-sets

This code relies on generic shared interrupt support just commited to
kern_intr.c (plus the modifications of isa.c and isa_device.h).

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.

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 !

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
