include <machine/psl.h> for the PSL_DR definition (for KGDB enabled build only).

declare batl for PPC_OEA601 only, since it is unused by OEA or OEA64_BRIDGE.

- Drop unused opt_ddb.h.
- Include missing opt_ppcarch.h.

Style and cosmetic changes. No binary changes intended.

Ifdef out all the MPC601 code with PPC_OEA601.  Now only arches that have the
possibility of running on an MPC601, are infected with all the extra code
and nops that it added.

Also, fix compilation that I broke with the pmap code, by adding
oeacpufeat to the locores of various ppc arches.  Noted by mlelstv.

Rewrite a big chunk of the pmap and locore code for powerpc to better
deal with the 64bit bridge mode.  pmap changes by Matt Thomas, rest by myself.

Change pmap.c to work similar to exec_elf.c to allow us to compile in
multiple pmaps to a single kernel.  This allows the pmap for bridge64 to
co-exist with the 32bit pmap.

Yank __HAVE_PMAP_PHYSSEG from all the oea code.

Add a new global, "oeacpufeat", which is used early in locore to determine
certain cpu features.  This allows us to conditionalize code early in the boot
for certain CPUs that have special needs.

Yank most of the ifdef PPC_OEA_BRIDGE64 code from almost every file it was
found in.  Some of it seemed incorrect, and my 7044 booted just fine
without it.  It would appear that the bridge cpus treat BAT instructions
as nops, so they seem to be safe.

In ofppc, check the oeacpufeat, and if we are on a 64bit proc, clear
MSR[SF], and ASR[V].

With all of these changes, a kernel with both PPC_OEA and PPC_OEA_BRIDGE64
will boot on the POWERIII-2 cpu.  However, it will not yet boot on a 32bit
cpu, because of CACHELINESIZE.  Work remains to be done there to fix that.

Local variables bat{u,l} are only needed by OEA code, so ifdef them.

On ibm405 (which the true meaning of PPC_IBM4XX), anything outside
kernel VM range is supposed to be mapped via reserved TLB entries,
so allow such VAs through.

Fixes kgdb failure observed by Jean-Francois Boudreault on port-powerpc
(thanks for testing, too).

Fix an apparent syntax error.

Pull in SPRs via <powerpc/spr.h> in this single instance, and dispose of

Fix PowerPC ports build with KGDB.

Reorganize the way powerpc port install machine specific headers.
Use <powerpc/oea/bat.h> exclusively and remove <machine/bat.h> and
<powerpc/bat.h>.  Remove unneeded <machine/cpufunc.h>.  To insure
1:1 correspondence of <powerpc/FOO.h> to <machine/FOO.h> include
"../../powerpc/include/Makefile" in "arch/FOO/include/Makefile".
Incororpate <byte_swap.h> into <bswap.h> and then byte_swap.h

__KERNEL_RCSID()

Rename PPC_MPC6XX to PPC_OEA (and any mpc6xx reference to oea).

MPC601 support bits:
* install 601-specific DSI and RUNMODETRC trap handlers
* save/restore MQ in trapframe, add MQ hooks to DDB
* extend battable to 512 entries to hold the 601's 8M translations
* instead of adding I/O to BAT starvation, set up segment registers
  for Memory-Forced I/O Controller Interface Access
* sync after tlbie

Make it compile on MPC6xx.  I'm not sure about MPC40x.
