* Firmware is the flattened representation of 'struct aic_project'
   data structure in aic3xxx_cfw.h
* We will release a default firmware for all family of AIC CODECs under GPL
* Any other firmware created by other tools using the
   data structure information in aic3xxx_cfw.h file will be licensed appropriately
   by the creator of such firmware.
