It's not just that. kexec:ing a new kernel from an older that has the old device tree breaks if you don't consider older device trees. Or you might have an old firmware with a flashed device tree that you need to keep compatibility with. You should either fix up the "broken" (not latest and greatest) device trees in the wrapper before using them, or make sure that your code is still compatible with the old trees. The fact that the device tree source code is distributed with the kernel isn't an excuse to break backwards compatibility with older versions. -Olof _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
