The specific board based on > Exynos3250 might not need TMU feature.

If a particular board does not need this feature it needs to be disabled in the build config and only for any special requirements disable it in board file. -- Regards, Sachin. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
