The ARM license header is consistent throughout the code base.
We had previously received AMD legal approval to contribute bug fixes and feature enhancements to M5/gem5 under the existing license. Since the GPU model is a much more significant contribution of AMD IP, we had to go back to legal for further approvals, which led to them insisting on the new "For use for simulation and test purposes only" clause. How we ended up with different formatting on the standard BSD part in the process is a mystery to me though. - Steve ----------------------------------------------------------- This is an automatically generated e-mail.
