That should be doable now, right? I'd rather apply this to current scheme and then move everything once, instead of having maintainers go "Oh, I guess I need to move mine" and we end up with an onslaught of conflicting pull requests to move things apart. -Olof

While I'd like to see the whole thing converted, I was only asking about this one platform. That should be doable now, right? Rob

I think we're at a point where it's becoming quite awkward to keep it in a flat directory, yes. Best way to handle this is usually right before the closing of a merge window, so let's do it then. It'll be a conflict-ridden mess if we try to stage something in -next, so I'd rather just do it directly in our tree as a one-shot thing. -Olof

Having 'serial0' point to a disabled uart may easily break applications that expect the first one to be the console. Best make that serial0 = &uart2; and drop the other ones if only one of them is exposed on the board. If all three are usable, you should enable them all here, and make sure that the numbering of the aliases matches the labels on the board or its documentation. Arnd
