The basic idea I asked Gavin to implement is that since the FW needs to provide a bunch of DT updates to Linux at runtime in the form of new nodes below an existing one, rather than doing it via some new/custom format, instead, have it send a bit of FDT blob to expand under an existing node. As for the details of Gavin implementation, I haven't looked at it in details yet so there might be issues there, however I don't know what you mean by "overlays", any pointer ?
