We are on rev1.x silicon and I want to avoid greatly having to spawn a new .dts just for "fsl,elbc-1.2.1" that has some errata fix in it. If dtc was smarter and I had less duplication between the 40-50 .dts we have for our various parts I wouldn't care that match. > Is there anything in the p2020ds u-boot patches to set the elbc > version, or was that just a brush-off? I was hoping that Poonam would look at doing that, but there isn't anything right now. I can put out some code for u-boot to address the specific elbc issue if that will resolve this. - k
