Hi,

I have setup a hikey build using angstrom-next:

$ git clone git://github.com/angstrom-distribution/setup-scripts.git
$ cd setup-scripts
$ git checkout next
$ MACHINE=hikey ./oebb.sh config hikey
$ source environment-angstrom
$ bitbake-layers add-layer <path to angstrom's meta-96boards>
$ bitbake console-image

While building the kernel (linux-hikey_3.18) my build fails with:

/home/trevor/devel/yocto/hikey/board1/angstrom/next/build/tmp-glibc/work-shared/hikey/kernel-source/drivers/gpu/arm/utgard/Kbuild:37: 
*** DMA-BUF is incompatible with non-GPL license.  Stop.
make[5]: *** [drivers/gpu/arm/utgard] Error 2
make[4]: *** [drivers/gpu/arm] Error 2
make[3]: *** [drivers/gpu] Error 2
make[2]: *** [drivers] Error 2
make[2]: *** Waiting for unfinished jobs....

Any thoughts on why this might be happening?

Thanks and best regards,
     Trevor
