Seppo Ingalsuo c43666d6f0 EQ FIR: Add check and removal for trailing zeros in filter coefficients 
This patch adds removing of extra zeros in the FIR coefficients. The
zeros can happen in some responses due to fixed point quantization of
very small values. The zero taps consume DSP resources for nothing so
better to clean them out for EQ configuration data.

Sound Open Firmware Tools
=========================

This is a collection of open source tools used to develop open source audio
DSP firmwares for ALSA.

Building and Installing
=======================

./autogen.sh (only needed first time)
./configure
make
make install


rimage
======

rimage is used to convert ELF executable firmware files to the firmware file
formats used by the kernel drivers.

e.g.

rimage -i elf_file -o kernel_file -m machine

rimage can also convert kernel firmware formats to flat binaries formats to
assist in debugging :-

e.g. convert to flat binary, then ELF then dissasemble

rimage -i /lib/firmware/intel/reef-byt.ri -o image.bin -b -m byt

xtensa-byt-elf-objcopy -I binary -O elf32-xtensa-le -B xtensa image.bin image.bin.elf

xtensa-byt-elf-objdump -D image.bin.elf > image.dis.txt

tests
=====

To generate all test configuration files:

make tests
