Right, it uses USE_OF by default because the TEGRA_DT board was enabled. The defconfig should really be a superset of needed configs for running on most hardware out there (since we do a multiplatform kernel), so keeping it enabled on Tegra does make some sense. Also, the direction is to keep moving towards 100% device-tree (on tegra), it does make sense to keep it enabled. For testing, explicitly disabling it to compile-test will be needed for a while longer, but I don't expect to do much !USE_OF work (for tegra specifically) in the times ahead. When changing ARM-generic core code, you should probably pick a few other defconfigs and make sure those build as well -- that should cover those aspects. -Olof -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
