The Rockchip rk3288-EVB is a new addition to the farm (Thanks Rockchip!)

Heiko, I've noticed this is booting in linux-next and vanilla v3.17, but it's failing on current linus/master. I haven't been able to bisect this yet.

I can reproduce this in the current head of linus/master, the last log entries are

DMA: preallocated 256 KiB pool for atomic coherent allocations cpuidle: using governor ladder cpuidle: using governor menu

This is missing a quite crucial clock change, that is coming via mturquette's tree. The added pl330 dma controllers do very agressive clock gating, which cascades up through the clock-tree and deactivates crucial core clocks. There is a change in the clock tree protecting these.

So as expected, taking linus/master and merging in clk-for-linus-3.18 from the clock tree makes the system boot again.
