Fix error messages: print "Division" instead of "Divide"; print
multiplier-like, addition-like and logical operator tokens instead of
garbage (usually the command name).
ddb has a primitive lexer with excessive information hiding that makes
it hard to find even the point in the line where a syntax error is
detected. Old ddb just printed "Syntax error" and this was unimproved
in most places by printing a garbage token.
Early use of vm86 depends on the PIC being reset to mask interrupts,
but r286667 moved PIC initialization to after where vm86 may be first
used.
Move the PIC initialization up to immdiately before vm86 initialization.
All invocations of diff that I tried display this move poorly so that it
looks like PIC and vm86 initialization was moved later.
r286667 was to move console initialization later. The diffs are again
unreadable -- they show a large move that doesn't seem to involve the
console. The PIC initialization stayed just below the console
initialization where it could still be debugged but no longer works.
Later console initialization breaks mainly debugging vm86 initialization
and memory sizing using ddb and printf(). There are several printf()s
in the memory sizing that now go nowhere since message buffer
initialization has always been too late. Memory sizing is done by loader
for most users, but the lost messages for this case are even more
interesting than for an auto-probe since they tell you what the loader
found.
vm86 uses the tss, but r273995 moved tss initialization to after where
it may be first used, just because tss_esp0 now depends on later
initializations and/or amd64 does it later.
vm86 is first used for memory sizing in cases where the loader can't
figure out the size or is not used. Its initialization is placed
immediately before memory sizing to support this, and the tss was
initialized a little earlier.
Move everything in the tss initialization except for tss_esp0 back to
almost where it was, immediately before vm86 initialization (the
combined move is from before dblflt_tss initialization to after). Add
only early initialization of tss_esp0, later reloading of the tss, and
comments. The initial tss_esp0 no longer has space for the pcb since
initially the size of the pcb is not known and no pcb is needed.
(Later changes broke debugging at this point, so the nonexistent pcb
cannot be used by debuggers, and at the time of 273995 when ddb was
almost able to debug this problem it didn't need the pcb.) The
iniitial tss_esp0 still has a magic 16 bytes reserved for vm86
although I think this is unused too.

This adds support for performing platform_reset() on all supported
devices, using early boot enumeration of chipc capabilities and

- Added Broadcom-specific MIPS CP0 register definitions used by
BCM4785-specific reset handling.
- Added a bcm_platform structure for tracking chipc/pmu/cfe platform

- Extended the BCMA EROM API to support early boot lookup of core info
(including port/region mappings).
- Extended platform_reset() to support PMU, PMU+AOB, and non-PMU

Rather than enabling the I/O MMU when the vmm module is loaded,
defer initialization until the first attempt to pass a PCI device
through to a guest. If the I/O MMU fails to initialize or is not
present, than fail the attempt to pass a PCI device through to a
guest.
The hw.vmm.force_iommu tunable has been removed since the I/O MMU is
no longer enabled during boot. However, the I/O MMU support can be
disabled by setting the hw.vmm.iommu.enable tunable to 0 to prevent
use of the I/O MMU on any systems where it is buggy.

Summary:
First time BSS is cleared in booke_init(), Second time it's cleared in
powerpc_init(). Any variable initialized between two those guys gets wiped out
what is wrong. In particular it wipes tlb1_entries initialized by tlb1_init(),
which was fine when tlb1_init() was called a second time, but this was removed
in r304656.
