I followed the step to generate the firmware v4l-coda960-imx6q, and
tested it on next-20140725 with patch 'ARM: dts: imx6qdl: Enable CODA960
VPU' applied on top of it.  But I got the error of 'Wrong firmwarel' as
below.

[    2.582837] coda 2040000.vpu: requesting firmware 'v4l-coda960-imx6q.bin' for CODA960
[    2.593344] coda 2040000.vpu: Firmware code revision: 0
[    2.598649] coda 2040000.vpu: Wrong firmware. Hw: CODA960, Fw: (0x0000), Version: 0.0.0

What am I missing here?
