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.

introduced ppc4xx_tlb_reserve() API.

* 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

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.

sys/arch/powerpc/include/ibm4xx/tlb.h: revision 1.6
sys/arch/powerpc/include/ibm4xx/pmap.h: revision 1.20
Misc non-critical fixes.
- __asm --> __asm volatile for sure
- turn DEBUG code in __asm into DIAGNOSTIC code in C
- style
ppc4xx_tlb_enter(): invalidate entry after clearing MSR for sure.
pmap_procwr(): use dcbst instead of dcbf as a tiny optimization.
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.
Fix pmap_procwr().
While we need to turn off IMMU, DMMU should be kept on. Otherwise,
dcbst (and also icbi probably, though not documented clearly both
for 405 and 403) should not work correctly.
