I think the current status of zcu102 booting is this, so please correct me if
I'm wrong here:
Booting with SPL works with u-boot-xlnx current master
(20fd28dcadb5c98e0671ae12a49acd4502517d86)
However, this version lacks the PSCI integration of the current u-boot kernel.
So if you boot a kernel with it, you'll have to disable pcsi (e.g. in the
devicetree) to get it to boot at all. And then you end up with a single-core
system because the kernel cannot start the other cores without the PSCI firmware.
Current 'mainline' u-boot appears to have support for PSCI for ARMv8, so that
might yield a working system. However, this version still lacks the
initialization support for mpsoc boards, so it won't boot at all.
Would merging these trees yield a setup that can actually boot and have
multiple CPUs?
