"Comment #4 From Alan 2010-01-19 17:23:25 ------- Look up 'Estoppel' Firmware needs moving into using the firmware loader however." the firmware was submitted by the Cirrus Logic and cannot be taken back (relicensed to more restrictive license after submission). I assume it means that the firmaware can be distributed but in the binary only form. However, if you prefer to drop the old firmware completely I can make such a patch.
