    What's the state of the platform code? Is this based on Catalin's
    Cortex-M3 tree? I've heard a few people express interest in getting
    various M3 based SoCs supported mainline and I think that would
    be a good idea, but I would also expect that device tree is one
    of the lesser problems here.
