gem5 requires armv7, and we learnt that the versatiledb we were using was pre-v7. We could have moved to -M vexpress-*, but in the end decided to go for -M virt due to its simpliciy, and uniformity with aarch64. platform_device: does not work anymore and was removed, since it was tied to versatilepb. We left a mention on the README and removed all in tree source. The QEMU patch is still left as it was. As a consequence, the linux tree had no other patches, and we now use vanilla linux by default, which is a great thing for reproducibility. Another consequence is the /poweroff.out works for arm -M virt, and we removed all mentions of the problem.
