- 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.
