Hi. Thanks for this patchset, but I'm afraid this doesn't seem to me like something that should be in QEMU. As you say, you can easily turn the dtb blob into a source file with dtc. That gets you a definitely-correct disassembly of the blob, and we don't need to maintain a possibly-buggy reimplementation of the dtb disassembler in QEMU. thanks -- PMM
