Why is CONFIG_OF_EMBED not recommended for production devices?
It's kind-of a question for the devicetree folks. The last time (a while back now) I asked for some general advice on how a DT should be shipped with hardware, being able to update the DT without replacing the whole of firmware was seen as a good thing. Combine this with that we should try (yes, we can't today due to incompatible bindings) share the DT between U-Boot and the kernel (or really, U-Boot and anything but again, last I checked the BSD bindings were very very different), embedding doesn't seem good.
Addressing the binding differences, it's hard to see what these are right now since the sorting and other churn in the Linux device tree files. I think it would be good to sync the U-Boot files to the Linux ones so we can see what bindings still differ.
Yes, agreed.
