Hmm...yeah, 5800 doesn't boot without this and 3250 is also same
situation. In this time, soc_is_exynos0000() is required and I think, we
need to sort it out next time. Let's do one by one...;)
Arnd, Olof how do you think about this? I agree with Olof's suggestion
that we need to add only dt for new SoC but we need more time...
Thanks,
Kukjin
