Similar for patch 3/4. This makes it a lot more obvious that it's selecting an option based on the runtime SoC, rather than just a bunch of if conditions that each may or may-not be doing similar things. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
