EQ: Add equalizer control tool eqctl
This patch adds a simple control tool to setup during runtime (idle) the IIR or FIR equalizer with new coefficients configuration. It is useful in tuning of the equalizers. The tool also has capability to read the EQ configuration from DSP. Run "sof-eqctl -h" to see usage. The directory SOFT/tune/eq contains tool to create EQ setup data.

How to use sof-eqctl tool
|
||||
=========================
|
||||
|
||||
This tool helps to access the ext bytes or tlv bytes control of SOF
|
||||
equalizer components eq_iir and eq_fir. Please find the documentation
|
||||
in https://thesofproject.github.io/latest/getting_started/index.html
|
||||
for more information.
