They don't; the core support is so small it's not worth having the ifdefs in it; just a few K. As such, it seems simpler to just always compile in the core support, and remove the need for all the ifdef nests in mach-tegra/. The bulk of the differences are different drivers for different chips. -- 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
