Not much to see here, most of the juice is over at:

The kernel driver (m1n1.fw.avd) only really pipes the instruction stream
into the respective hardware FIFOs and then hushes the interrupt lines.
Most of the work (bitstream syntax parsing and instruction generation)
is done in the avid repo above.
I'm hoping to keep this userland-kernel separation in the very imminent
actual driver.
experiments/avd.py: Decode on the command line. Read file for usage.
experiments/avd_e.py: Decode via emulated instruction stream.
experiments/avd_f.py: Decode via Cortex-M3 firmware (for debugging).
hv/trace_avd.py: Tracer. Read file for usage.
m1n1/fw/avd/__init__.py: Driver base class (power, tunables, etc).
m1n1/fw/avd/decoder.py: Codec-specific decode logic + mini media player.

PR'd because the driver prototype has been stable for a while.
