At the same time, allow crime_intr_establish() to fall through to
mace_intr_establish(). mace devices now call cpu_intr_establish().

Do not directly reference crime_*() routines, go through the platform
struct pointers instead.

NULL -> 0

Apply a bunch of patches written by Christopher SEKIYA
(with several cosmetic changes by me) which fixes O2 (IP32) support.

Now my R5000 O2 works fine in multiuser with on-board AIC7880 SCSIs
and several PCI network cards (but only on serial console yet).
L2 cache on R5000/Rm5200 is still disabled for now, but it will be
fixed later, hopefully.

Handle 64bit DMA addresses on PCI for platforms that can (currently only
enabled on amd64). Add a dmat64 field to various PCI attach structures,
and pass it down where needed. Implement a simple new function called
pci_dma64_available(pa) to test if 64bit DMA addresses may be used.
This returns 1 iff _PCI_HAVE_DMA64 is defined in <machine/pci_machdep.h>,
and there is more than 4G of memory.

Fix a bug that would cause the PCI fixup to assign addresses beyond the range
of KSEG0/1 mappable PCI window (the MEG_ALIGN macro was aligning to *16* MB
instead of *1* MB due to an extra 0 in the round-to constant). Also, allow
the PCI code to fix up all functions of a multifunction device; both from
Chris Sekiya, with a bit of massaging by me.

PCI fixup code for the O2. Tested with a range of 32 and 64-bit network
cards, but not much else. Seems to work fairly well, though.

Use aprint_normal() for cfprint routines.

Use CFATTACH_DECL().

* Add "pcitag_t *pba_bridgetag" to pci_attach_args. This is set to
NULL for root PCI busses. For busses behind a bridge, it points to
a persistent copy of the bridge's pcitag_t. This can be very useful
for machine-dependent PCI bus enumeration code.
* Implement a machine-dependent pci_enumerate_bus() for sparc64 which
uses OFW device nodes to enumerate the bus. When a PCI bus that is
behind a bridge is attached, pci_attach_hook() allocates a new PCI
chipset tag for the new bus and sets it's "curnode" to the OFW node
of the bridge. This is used as a starting point when enumerating
that bus. Root busses get the OFW node of the host bridge (psycho).
* Garbage-collect "ofpci" and "ofppb" from the sparc64 port.

Improve the interrupt code somewhat by having callers of xxx_intr_establish
pass in an interrupt handle (which is currently to the CRIME interrupt the
device is attached to) so the interrupt handlers know which device was the
one looking for attention.

While here, fix up PCI interrupt routing for both the on-board devices and
the PCI slots -- even though there is only one PCI slot in the chasis, the
hardware can accomodate up to three and provides an interrupt mapping for
all the PCI interrupt pins for both the internal SCSI & PCI slot and the
two "extra" slots.

Change pci_intr_map to get interrupt source information from a "struct
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".

This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.

For ports that wire up pciide in compatibility mode, have
them define __HAVE_PCIIDE_MACHDEP_COMPAT_INTR_ESTABLISH
in pci_machdep.h and pciide_map_compat_intr() only calls
pciide_machdep_compat_intr_establish() if that preprocessor
define exists.

Ports that don't need to do this no longer need to supply a
dummy function.
