Should this patch be pushed earlier so it isn't used before it's created? I'm not sure how much that matters.

It is. Is that a problem?

Add support for tegra30 SoC. This includes a device tree compatible type for this SoC ("nvidia,tegra30") and adds L2 cache initialization for this new SoC. The clock framework is still missing, which prevents most drivers from working.
