I tried your branch above on Odroid U3 and it fails to boot.
next-20170125 works fine. exynos_defconfig, booting from microSD.

Board hangs (silently) on:
[    2.283437] usb 1-3: new high-speed USB device number 3 using exynos-ehci
[    2.473786] usb 1-3: New USB device found, idVendor=0424, idProduct=3503
[    2.474856] usb 1-3: New USB device strings: Mfr=0, Product=0, SerialNumber=0
[    2.482656] hub 1-3:1.0: USB hub found
[    2.486017] hub 1-3:1.0: 3 ports detected
[   55.037205] random: crng init done

Full log attached.

Best regards,
Krzysztof
