[Sound-open-firmware] [RFC PATCH 0/6] Host testbench

[Ranjani Sridharan]

This set of patches introduces the testbench for audio processing
components in SOF. The testbench enables functional/quality
testing of SOF components. The testbench reads in audio samples
from a file and write out the processed samples to the output file.

The host directory includes common code with routines for topology parsing
and setting up sof ipc, scheduler and processing pipelines. It also
includes simpler implementations for SOF features such as tracing.
It also includes a new file component that allows reading in or writing
out samples from/to a file.

The host directory also includes the testbench for setting up pipelines
based on a test topology. It reads in input samples from a file
, schedules pipeline copy and copies the processed sample to the output
file. The output file can be used to perform audio quality tests using
matlab/octave. Currently it supports only volume pipelines. 
Support for other components such as src/eq will be added soon.

Ranjani Sridharan (6):
  host: add host testbench common source and header files
  host: add new component for file IO
  host: add testbench program
  host: include host testbench directory for compilation
  scripts: add scritps for building host library and invoking the
    testbench
  doc: add README for host testbench
