Adding comment about FreeBSD/VoCore kernel testing.

Fake MIPS 24KEc model, used by VoCore.

Adding a minimal VoCore palmbus skeleton, enough to print boot messages.

Minor progress on booting Linux/VoCore. MIPS rdhwr CC is implemented as reading the COP0_COUNT register.

More clang fixes.

Updating for next step in potential VoCore emulation.

Some basic info about the VoCore address space.

Implementing the rorv (aka rotrv?) MIPS instruction.

Adding info to the unsupported page about how to start experimenting with Linux/VoCore kernels.

Adding a dummy VoCore machine skeleton using the old framework (with the wrong CPU type 4KEc instead of 24K).
