I applied this series (to u-boot-fdt/testing) but it requires a later
version of dtc than we use in our travis tests:

https://travis-ci.org/sglass68/u-boot/jobs/275239527

Could you please take a look? I don't think I can pull this in until I
know it can make it to mainline.

The good news is that with the new dtc my buildman test went through
with no errors.
