d4f824014d A bunch of things: 
- Clean up the way cpu-specific tlb/cache functions are configured
    and used.
  - Add a workaround for a problem whereby cpu* at superhyway? fails
    to probe.
  - Print more info about the cpu/cache.
  - Move the RESVEC handlers back into generic sh5 code and ditch
    the panic stack hack.
  - Make the on-chip SCIF device the default console on Cayman.
  - Add experimental support for booting via a standalone bootstrap
    program (not yet committed) and using the boot parameters passed
    in by it.
  - Add a few more SH elf constants.
  - Tick a couple of items off the TODO list.

80284bdc34 Arrange for non-panic debug sync/async exceptions to re-vector through the 
real sync/async exception handler instead of always calling panic_trap().
Otherwise, userland BRK instructions can halt the system.

4bb41ae2f2 Rework how KERNOBJDIR functions; now it's always determined with 
cd ${KERNSRCDIR}/${KERNARCHDIR}/compile && ${PRINTOBJDIR}
This is far simpler than the previous system, and more robust with
objdirs built via BSDOBJDIR.

The previous method of finding KERNOBJDIR when using BSDOBJDIR by
referencing _SRC_TOP_OBJ_ from another directory was extremely
fragile due to the depth first tree walk by <bsd.subdir.mk>, and
the caching of _SRC_TOP_OBJ_ (with MAKEOVERRIDES) which would be
empty on the *first* pass to create fresh objdirs.

This change requires adding sys/arch/*/compile/Makefile to create
the objdir in that directory, and descending into arch/*/compile
from arch/*/Makefile.  Remove the now-unnecessary .keep_me files
whilst here.

Per lengthy discussion with Andrew Brown.

a3885e9bdd - Change VM_MIN_KERNEL_ADDRESS to start at KSEG1 instead of KSEG0. 
- Overhaul the TLB management code such that we now keep track of
   the exact TLB slot at which a mapping was inserted, both for user-
   space and kernel mappings. This addresses #2 on the TODO list.

6a2132797e - Simplify early initialisation so we do most of it in C.

  steal KSEG0 pages for system tables.

c01b319dcc There seem to be some stability problems with the scif serial port driver 
at the moment, possibly as a side-effect of some yet-to-be-committed SH5
speed-ups.

Work-around it for now by using com0 as the console.

199e165526 Add a cacheop for purging/invalidating the whole operand/insn caches.

fa307a78a6 A couple of additions:

   a "heartbeat" indicator.

d1ad2ac4f2 Rather than referencing the cfdriver directly in the cfdata entries, 
instead use a string naming the driver.  The cfdriver is then looked
up in a list which is built at run-time.
