This returns 1 iff _PCI_HAVE_DMA64 is defined in <machine/pci_machdep.h>,
and there is more than 4G of memory.

Add support for the IBM 403GCX cpu. Enabled with "options PPC_IBM403".

Neither pci_dma64_available(), pci_probe_device(), pci_mapreg_map(9),
pci_find_rom(), pci_intr_map(9), pci_enumerate_bus(), nor the match
predicate passed to pciide_compat_intr_establish() should ever modify
their pci_attach_args argument, so make their pci_attach_args arguments
const and deal with the fallout throughout the kernel.

For the most part, these changes add a 'const' where there was no
'const' before, however, some drivers and MD code used to modify
pci_attach_args. Now those drivers either copy their pci_attach_args
and modify the copy, or refrain from modifying pci_attach_args:

Xen: according to Manuel Bouyer, writing to pci_attach_args in
pci_intr_map() was a leftover from Xen 2. Probably a bug. I
stopped writing it. I have not tested this change.

siside(4): sis_hostbr_match() needlessly wrote to pci_attach_args.
Probably a bug. I use a temporary variable. I have not tested this
change.

slide(4): sl82c105_chip_map() overwrote the caller's pci_attach_args.
Probably a bug. Use a local pci_attach_args. I have not tested
this change.

viaide(4): via_sata_chip_map() and via_sata_chip_map_new() overwrote the
caller's pci_attach_args. Probably a bug. Make a local copy of the
caller's pci_attach_args and modify the copy. I have not tested
this change.

While I'm here, make pci_mapreg_submap() static.

pmap_remove_all(): Return a boolean value to indicate the behaviour. If
true, all mappings have been removed, the pmap is totally cleared out, and
UVM can then avoid doing the work to call pmap_remove() for each map entry.
If false, either nothing has been done, or some helpful arch-specific voodoo
has taken place.

Retire tlbpid_t (u_short):

- PID (ctx, ASID) is 8-bit length, not half word.
- For struct pmap, no need to use integer types smaller than word as
pm_ctx because of alignment.
- For ppc4xx_tlb_enter(), we need word-length storage for pid (and msr).

Better to rewrite pmap module with more suggestive integer types rather
than char, int, long, and so on.

Make pmap_kernel() a MI macro for struct pmap *kernel_pmap_ptr,
which is now the "API" provided by the pmap module. pmap_kernel()
remains as the syntactic sugar.

Bonus cosmetics round: move all the pmap_t pointer typedefs into
uvm_pmap.h.

Thanks to Greg Oster for providing cpu muscle for doing test builds.

Replace the Mach-derived boolean_t type with the C99 bool type. A
future commit will replace use of TRUE and FALSE with true and false.

Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.

implement pmap_wired_count(). fix some places we would forget to splx().
move the parts of pte.h that were used into pmap.c (since they were really
pmap-internal details) and delete ibm4xx/pte.h. other misc cleanup.

Remove the unused MKTTE macro.

remove an unused proto.

Switch ibm4xx over to using the more flexible powerpc bus_space/bus_dma code.

Use PAGE_SIZE rather than NBPG.

it really helps to get the stub right before cutting + pasting it 27 times.
alas, I did not. doh.

add pmap_remove_all() hook (empty on most platforms so far).

pmap improvements:

Remove the cache flush routines that have been moved to cpu.c

Make sure we clear out the unused PA bits in the TTE which causes breakage
on some MMU models.

Add a port to IBM's PPC405GP Reference Board (the "walnut")
by Eduardo Horvath and Simon Burge of Wasabi Systems.

IBM 4xx series CPU features:
- New pmap and revised trap handler.
- Support on-chip timers, PCI controller, UARTs
- Framework for on-chip ethernet and watchdog timer.
General PowerPC features:
- Add in-kernel PPC floating point emulation
- New in{,4}_cksum that is between 1.5 and 5 times faster than the
old version depending on CPU type.
General changes:
- Kernel support for generic dbsym-style symbols.

Make ibm4xx kernels compiled by clang.

As clang cannot correctly assemble m[ft]pid:
- for asm sources, use m[ft]spr from/to SPR_PID
- for C sources, use M[FT]PID macros (see include/ibm4xx/spr.h)
This is ugly...

No binary changes for GCC-compiled kernels.

Add 403 family processors other than 403GCX.

Support PowerPC 405EX/EXr.
1. Add some new source and header files.
(MAL(split) and RGMII(new) relations for EMAC)
2. Create dcr4xx.h. Its moved from dcr405gp.h. Also remove dcr405xx.h.
3. intr.c supports MULTIUIC with virtual-irq. likes to oea.
support 32-virq/128-hwirq.
4. multiple emac support.
5. WALNUT and VIRTEX_* includes arch/powerpc/conf/files.ibm4xx.
6. WALNUT pci uses arch/powerpc/ibm4xx/pci/.

Split <powerpc/spr.h> into a common <powerpc/spr.h> and <powerpc/XXX/spr.h>

G/C misleading <evbppc/tlb.h>. Use <powerpc/ibm4xx/tlb.h> directly.

Retire tlbpid_t (u_short):

- PID (ctx, ASID) is 8-bit length, not half word.
- For struct pmap, no need to use integer types smaller than word as
pm_ctx because of alignment.
- For ppc4xx_tlb_enter(), we need word-length storage for pid (and msr).

XXX
Better to rewrite pmap module with more suggestive integer types rather
than char, int, long, and so on.

* ppc4xx_tlb_reserve(): allocate "reserved" TLB entries dynamically
* ppc4xx_tlb_mapiodev(): resolve pa to va from reserved TLB entries

OK by matt@

XXX we'll keep TLB_NRESERVED defined until we fix explora to use new API

Use default PAGER_MAP_DEFAULT_SIZE for ARM and PowerPC, exception
acorn26. This bumps the KVA reservation from 4MB to 16MB and avoids
long hangs on my Cubietruck under IO. acorn26 is kept as it does have a
ridiculous low 32MB KVA limit.

PowerPC now exports a common view of cpu.h, vmparam.h and pmap.h
when building a MODULAR kernel or compiling _MODULE.
It should be noted that MODULAR or _MODULE export a view of the kernel
as being MULTIPROCESSOR (even if isn't).
The shared pmap TLB uses mdpg in places where it used mdpg to avoid
deadly embrance inclusion problems.

Merge from uebayasi-xip:

Teach TLB miss handler (pmap_tlbmiss()) to map "Expansion ROM" area as
PA == VA. Now we don't need to reserve a TLB entry for it.

Remove incomplete, never worked dynamic run-time memory registration
(uvm_page_physload(9)). This functionality will be re-added later.

Use PAGE_SIZE rather than NBPG.

Make PAGE_SIZE, PAGE_SHIFT, and PAGE_MASK compile-time constants for
PowerPC processors.

Re-arrange things in evbppc & powerpc to support OEA-based eval boards
in evbppc. OEA-based board(s) to be added later.

Move ibm4xx vmparam.h to powerpc/include/ibm4xx directory. Add a stub
vmparam.h to choose the right vmparam. This is needed so evbppc can host
both ibm4xx and oea based eval boards.
