Great, thanks!

I see these patches are already in mainline post-4.11, so that's great.

I guess this change isn't strictly needed because of the symlink, but
OK.

This shouldn't be dropped (after changing to 4.11) as the defconfig
would otherwise break whenever 4.12 gets added.

Committed to next with that fixed, thanks.

I see you are still using a relatively old u-boot and ext3. Any reason
to not use 2017.05 and ext4?
