[PATCH v6 05/11] arm: Set PSCI to 0.2 for HVF


From: Alexander Graf
Subject: [PATCH v6 05/11] arm: Set PSCI to 0.2 for HVF
Date: Wed, 20 Jan 2021 23:44:38 +0100

In Hypervisor.framework, we just pass PSCI calls straight on to the QEMU 
emulation
of it. That means, if TCG is compatible with PSCI 0.2, so are we. Let's 
transpose
that fact in code too.
