as mentioned in another thread. linux-yocto needs to backport
https://patchwork.ozlabs.org/patch/403787/
to beging with. I have 3.8 running on beaglebone white but thats not linux-yocto

there is a patch or two in there that needs to go upstream into kernel
as well but I havent bothered yet.

I was not able to boot linux yocto 3.19 few weeks ago on any of
emulators when build with gcc5
rootfs did not have any issues.

I also have 3.10 compiling and booting on another Arm platform
