Liam Girdwood cd0eb84aca rmbox: move trace into separate parser function to ease future work. 
Move trace handler into separate function to make it easier to add new
trace features. Make sure we only support 64 bit timestamps.

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
