[PATCH 4/8] arm: Synchronize CPU on PSCI on

From: Alexander Graf
Subject: [PATCH 4/8] arm: Synchronize CPU on PSCI on
Date: Thu, 26 Nov 2020 22:50:13 +0100

We are going to reuse the TCG PSCI code for HVF. This however means that we
need to ensure that CPU register state is synchronized properly between the
two worlds.

So let's make sure that at least on the PSCI on call, the secondary core gets
to sync its registers after reset, so that changes also propagate.
