I have a very weird experience with snowball right now. I noticed this
yesterday when I decided to look at why multi_v7_defconfig doesn't
boot on it:

* u8500_defconfig doesn't boot as a DT kernel, since the machine ID is
still enabled. If I disable the machine ID, it doesn't boot.
* Same for multi_v7_defconfig, since that is only DT: It doesn't boot.

Unfortunately I can't get to my home network right now to double-check
boot logs to see if this has changed behavior recently, I'll have to
do that later today. It'd be interesting to hear if you have the same
experience w.r.t. DT on u8500_defconfig though.
