19b7ffd1b8 Prefer new location of pci include files (which have only been in the
tree for two or more years now), except in a few places where there's
code to be compatible with older versions of FreeBSD.

8bef1df9eb Remove ## concatination in the CFGREAD and CFGWRITE macros, as gcc3 complains
about them & they are not needed.  Same fix as to tsunami_pci.c.
(not surprising, as this code was cut and pasted from there when I wrote it).

030cb46918 recover from namespace collision caused by un-static'ing pci_alloc_resource()

a0e512b219 Make sure that all resource allocation is handled in the pcib device, not
the chipset. This is already how the multi-hose systems handle resource
allocation and it fixes a bug where dense and bwx memory allocations were
not handled properly.

bb0d0a8efc Next phase in the PCI subsystem cleanup.
- Move PCI core code to dev/pci.
 - Split bridge code out into separate modules.
 - Remove the descriptive strings from the bridge drivers.  If you
   want to know what a device is, use pciconf.  Add support for
   broadly identifying devices based on class/subclass, and for
   parsing a preloaded device identification database so that if
   you want to waste the memory, you can identify *anything* we know
   about.
 - Remove machine-dependant code from the core PCI code.  APIC interrupt
   mapping is performed by shadowing the intline register in machine-
   dependant code.
 - Bring interrupt routing support to the Alpha
   (although many platforms don't yet support routing or mapping
   interrupts entirely correctly).  This resulted in spamming
   <sys/bus.h> into more places than it really should have gone.
 - Put sys/dev on the kernel/modules include path.  This avoids
   having to change *all* the pci*.h includes.

689634a3ea Convert the pcib_{read,write}_config args from signed to unsigned,
like the args to the config space accessors these functions replaced.

This reduces the likelyhood of overflow when the args are used in
macros on the alpha.  This prevents memory management faults when
probing the pci bus on sables, multias and nonames.

cae70b8d4c Introduce explicit break statements in the various chipsets'
foo_pcib_[read|write]_config() functions rather than relying on
a break or return being in the CFG macro.

This fixes a panic later in the boot process on a UP1000.  From
inspection, it looks like this fixes a similar problem in the tsunami code.

21c3015a24 * Completely rewrite the alpha busspace to hide the implementation from
the drivers.
* Remove legacy inx/outx support from chipset and replace with macros
  which call busspace.
* Rework pci config accesses to route through the pcib device instead of
  calling a MD function directly.

With these changes it is possible to cleanly support machines which have
more than one independantly numbered PCI busses. As a bonus, the new
busspace implementation should be measurably faster than the old one.
