68ab2e8672 The previous commit broke kernel builds on alpha (and probably ia64).
#ifdef away the offending code until somebody with more newbus fu than
me can figure out where to put a default function that returns 255
without touching each alpha chipset driver..

9bf4bbcaf7 When a pci device hasn't had an interrupt routed to it (signified by
the intline of 255) go ahead and route the interrupt when we allocate
an interrupt.

b6c8407840 Get out the roto-rooter and clean up the abuse of nexus ivars by the
i386/isa/pcibus.c.  This gets -current running again on multiple host->pci
machines after the most recent nexus commits.  I had discussed this with
Mike Smith, but ended up doing it slightly differently to what we
discussed as it turned out cleaner this way.  Mike was suggesting creating
a new resource (SYS_RES_PCIBUS) or something and using *_[gs]et_resource(),
but IMHO that wasn't ideal as SYS_RES_* is meant to be a global platform
property, not a quirk of a given implementation.  This does use the ivar
methods but does so properly.  It also now prints the physical pci bus that
a host->pci bridge (pcib) corresponds to.

28ea1bf869 When dumping the 'found devices' list in verbose mode, actually show the
bus/slot/function numbers.  The old PCI code used other markers or
something, but without it here under the new pci code it is very hard to
tell which device is which (this only affects bootverbose mode).

f7c7ba14bf If a base address register has been set up by the BIOS, but the relevant
enable bit hasn't been set in the command register, set the bit and
honour the register.  It seems that quite a few lazy BIOS writers
aren't bothering to do this, which upsets the existing code and causes
us to miss out on properly-configured devices.

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.

30d1c11e3a Encapsulate the old PCI compatability support and APIs completely under
"options COMPAT_OLDPCI".  This option already existed, but now also tidies
up the declarations in #include <pci/pci*.h>.  It is amazing how much stuff
was using the old pre-FreeBSD 3.x names and going silently undetected.

3aae7b16d2 Fixed the type of some ivar access functions. Ivars have type uintptr_t,
not u_long.  On i386's with 64-bit longs, returning u_longs indirectly
in (more than) the space reserved for uintptr_t's tended to corrupt the
previous frame pointer in the stack frame, so it was not easy to debug.
The type mismatches are hidden by the bogus cast in DEVMETHOD().

f7b7769172 * Factor out the object system from new-bus so that it can be used by
non-device code.
* Re-implement the method dispatch to improve efficiency. The new system
  takes about 40ns for a method dispatch on a 300Mhz PII which is only
  10ns slower than a direct function call on the same hardware.

This changes the new-bus ABI slightly so make sure you re-compile any
driver modules which you use.

80060e8897 Connect the ISA and PCI compatability shims to an option. In this case
it's options COMPAT_OLDISA and COMPAT_OLDPCI.  This is meant to be a
fairly strong incentive to update the older drivers to newbus, but doesn't
(quite) leave anybody hanging with no hardware support.  I was talking with
a few folks and I was encouraged to simply break or disable the shims but
that was a bit too drastic for my liking.

17d75f8ecb Alpha 8200 port: Until we fix things better, determine which alpha CPU
platform we're running on so we know how many bits to reserve at the top
end for the 'hose' value. It turns out that there's *just* enough room
to support all possible hoses on TurboLaser.

cebf86fa3f Put a FYI in the compatability shims so that people are aware that they
are using an old unconverted driver.  Most (if not all) of the drivers
for common hardware are newbus these days.  However, we don't want
to encourage people to take the easy way out and write new drivers
using the shims.  This is just passive "encouragement".

ioctls are documented, but the PCIOCATTACHED ioctl is not documented
because it is not implemented.

fe0d408987 Remove the 'ivars' arguement to device_add_child() and
device_add_child_ordered().  'ivars' may now be set using the
device_set_ivars() function.

This makes it easier for us to change how arbitrary data structures are
associated with a device_t.  Eventually we won't be modifying device_t
to add additional pointers for ivars, softc data etc.

Despite my best efforts I've probably forgotten something so let me know
if this breaks anything.  I've been running with this change for months
and its been quite involved actually isolating all the changes from
the rest of the local changes in my tree.

5700c63bc7 Make the pci driver compat shim return a preference for probe
rather than an "it's mine!" so that other newbus-aware drivers can
bid for the device too.  This should allow the sym driver to out-bid
the ncr driver for devices it supports without having to modify ncr.c
at all.  ncr would then function as a catch-all.

The reason for them being there in the first place is that every
motherboard comes with USB kit and this way it looks more pretty (peter).
The real solution will be to define some method of detaching a driver
