Seppo Ingalsuo 0913d7c83a EQ: Fix an integer type bug in IIR coefficients blob packer 
This patch adds explicit conversion to signed int32 type for response to
channels indices in assign_response and filter coefficients. The bug was
visible if trying to activate in IIR blob the per channel filter bypass
by having a negative value (-1) in any of channel assigns. Octave assumed
the type to be unsigned and produced wrong configuration bytes.

The filter coefficients are already integer type from previous
quantization code in the conversion process. However it does not hurt to
have extra safety to avoid similar issue as assign.

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
