This patch adds a shell script sof_test_perf.sh that measures
gain, frequency response, and total harmonic distortion plus
noise for a remote device.
Matlab or Octave is needed. The shell script launches by default
Octave to process the signal generation and test results analysis
scripts.
The remote device must be set to be accessible by ssh without
passwords. An external high quality USB sound card is recommended
as analog interface to connect to test device's analog interface.
The configuration file sof_test_perf_config.m must be edited for
the remote device's user account, audio device, audio format, and
capture sound card audio device, and audio format.
