Hm...I could understand somewhat;) but DT can also specify "bootargs" in dts file, which can support per-board-wide spec too, like the above sum of carveout needed from all drivers. I just want to avoid introducing a new parameter additionaly if we can make use of the existing mechanism. -- 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
