One of the developers said they refresh the files from the gnu/linux tree every now and then. I looked in the sys/boot/fdt directory and only found one FDT file for IMX6= : /head/sys/boot/fdt/dts/arm/imx6q.dtsi This was written by Ian Lapore and is BSD licensed. If this is the base for the DTB, then you're fine (it's somewhat different than the GNU copy). However... If you look in /src/sys/gnu/dts there are quite a few files that are specific to the IMX6 but for different boards and configurations. Some of them are GPL, some are dual or "other" licensed. I don't remember the order they are applied or how the binaries are compiled but any GPL'd file included would contaminate the binary (the GNU base IMX6q.dtsi is GPL). As Warner pointed out: give them the source code for u-boot and you're compliant with the GPL! In *my opinion*, if you had to build a custom DTS file for a custom board, there is no reason you couldn't, er, "cross reference" values from a GPL'd files and add it to your own DTS with a different license. The values in DTS files are not intellectual property of the author per se, rather settings specified by the hardware vendor. So long as you "write your file from scratch" (e.g. have a copy of the Freescale IMX6 reference manual on hand that you could point to as the source of your information), then you could apply any license you want to your "new" file? Thoughts? $0.25 Russ >> -> and also is h264 freescale hardware codec exploited in free bsd Good question, I would like to know the answer to this as well. Even if FreeBSD supports a hardware codec(my guess is no), I think usually an application also needs to be compiled with the ability to use a hardware vs software codec? > Not sure about this.
