Well, this depends on the guest taking an undefined instruction exception on
the smc, then deciding to issue an hvc instead and *then* having the
hypervisor somehow translate that into a PSCI invocation. It could work, but
it sounds easy to mess up and relies on the PSCI firmware co-existing with
things like kvm.

We can have enable-method DT entries independent of the SoC and one of
them can be psci-hvc.

Just for clarification, AArch32 with virtualisation mandates the
security extensions, so the SMC can be trapped.

Good. Therefore this one is settled.

Looks we replied at the same time! Please see my other mail...
