That's a bug somewhere, the device tree should describe the hardware, and not necessarily the massaged format that the kernel wants it in to not trigger a bug. So I don't want to see this patch merged, I want to see a proper fix instead, please. There are also already other exynos platforms and device trees with more than 256MB in the memory node. Changing all of them this way seems unreasonable. -Olof -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
