From: Marc Zyngier <[email protected]> The ARMv8 architecture is supported by two publicly available software models: the Architecture Enveloppe Model, and the Foundation model.
Both are fairly similar to the Cortex-A57 from a kvm tools point of view, so we can hijack the A57 implementation to register these new targets.
