Note, we're not using dtb (device tree) yet in the qemu kernel. To do that properly, we'll need to get a qemu that works with U-Boot, etc. I know Linaro have put such a combination together, right? Should any of that be working with upstream bits yet? Brendan mentioned he'd tried poking briefly at the U-Boot that Linaro put together but it apparently didn't boot on our qemu (I know upstream was missing e.g. the model instantiation for the hardware memory controller, etc. in vexpress). I guess I could/should ping Peter Maydell? Is he the best contact?
