Where are those firmware files available?
Freescale currently distributes the firmware with their multimedia
packages, but in header hex array form; we are trying to find a proper
solution (hopefully by using the linux firmware repository) for
mainline.
The firmware-imx packages referenced in the Freescale meta-fsl-arm
repository on github.com contain VPU firmware files. Their use is
restricted by an EULA. For example:
http://www.freescale.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-3.0.35-4.0.0.bin
This contains the files vpu_fw_imx6q.bin and vpu_fw_imx6d.bin, which can
