Side note: only one compatible string for the real CPU please, running a DT bindings check should complain about that.

Really? This is 2020, not 2012 any more. Surely a new platform
boots using PSCI, and not *this*.


We don't currently support PSCI. The platform does not have TrustZone,
hence we don't use ATF.
AIUI, part of the purpose of ATF is to provide a nice standardised platform interface regardless of whether you care about Secure software or not. It shouldn't take much to knock up a trivial ATF port that just uses an internal spin-table for its PSCI backend - in fact I suspect that's probably just a copy-paste from the RPi3 port ;)
