Thanks. It was that part of the code that I spent the bulk of my time on. And although it is still has a few rough edges I would be happy for it to be used. > Also, I use a > different segment for the dtb rather than appending it to the > zImage; I think this approach would be better as it is less > restrictive, however a kernel patch is required to set r2 to the > appropriate address on entry to the new kernel. What are your > thoughts? I would prefer to avoid requiring kernel changes unless necessary - the kernels some of the boards I work with require DT since 3.5. However, I am happy to discuss this further, there certainly is merit to a clean implementation. > If you are happy with this I will submit a v2 set of patches. _______________________________________________ kexec mailing list kexec@lists.infradead.org http://lists.infradead.org/mailman/listinfo/kexec
