There were three suggestions in that thread, and persuading ARM Ltd to lift the restriction was one of them. The other two suggestions were: 1. For someone who is not bound by an ARM documentation license to do it, for example by working out the instruction set from reading Binutils, GCC and Linux code, and from reading books like the "ARM System Developer's Guide", by Sloss, Symes, and Wright, Elsevier 2004. The objection was raised that although that would be possible, it would prevent some people (who are bound by an ARM license) from contributing to the new Qemu. I think that would not be a problem if the ARMv6 support were in the form of a contributed patch, which those people could avoid looking at. 2. To add an explanation of why ARMv6 isn't supported to Qemu's FAQ. Anyone in a position to add to the FAQ? -- Jamie
