As you can guess, my objective is to get a model based on Versatile
Express with Cortex-A57 CPU which could be used to run an SMP Linux
kernel on system mode QEMU. So I decided to use the same model as ARM
FastModels provides. I could get ARMv8-A Foundation Platform model as
well, but it also uses spin table boot method. Seems there's no much choice.
