That's all. > Appreciate your help and I agree that upstream code should be held to a high standard. But since the DTS in mainline is pretty basic anyways (you can only boot to serial right now), is not really usable for other thing than development and keep adding the missing support. So I thought that we could do it in steps without creating that much work for the people trying to post the downstream patches and having to re-spin too many times. -- Best regards, Javier Martinez Canillas Core Platforms Red Hat
