We are using 6 states, 2 of them are substates:
init, idle, running, paused,
draining(sub state when transferring from running to idle)
pausing(substate when transferring from running to paused).
Don't response new command when in substates, only stay in
substates for limited timeout. e.g. 2ms for draing and 1ms
for pausing.

The tool-dir naming was a bit ambiguous so rename and fix build-all.sh
to use new name too.

The DMA controller needs to differentiate between host and DSP memory
regions. This can be done with a mask that is ORed with local DSP memory
locations.

This project provides an open source audio firmware infrastructure for audio
DSPs found on many modern devices. The intention is to allow developers to
create their own codecs, audio processing algorithms and pipelines using
the infrastructure and audio components provided by this project.
The project currently supports the Intel Baytrail and Cherrytrail audio DSP
platforms which use the Xtensa architecture.
The firmware source code is released under the BSD 3 clause licence.
