I also changed the property in the cpu nodes from model to compatible so that the exact CPU version can be specified. This isn't actually in any spec anywhere, but I need something to properly identify the different ARM cores.I don't see why this has to be in the device tree. It's not there on PPC. The exact CPU version is found through the PVR register on PPC, ARM also has cpu version and feature registers for runtime probing.I had been told that they runtime registers weren't reliable. If I'm misinformed, then yes the compatible value can be dropped from the cpu nodes.
Hi all, If it's not too painful to keep, I think it will be valuable if one want's to instantiate HW based/from this same device tree. For example for emulators. Cheers
