The secondary CPUs need an enable-method. Are you using PSCI or
spin-table?

This is on purpose.  We aren’t using either PSCI or spin-table.  Right
now the dts is for booting on a single core.  I can drop CPU1..CPU3 if
that helps.

We won't poke the CPUs without an enable-method, so personally I'm not
too worried either way about having the CPUs listed.

Which of spin-table/psci are you planning on using for SMP support, and
when would that be likely to appear?

Which exception level do CPUs enter the kernel? Even without a
virt-capable GIC booting at EL2 is less work for the FW and gives the
kernel a better chance of fixing things up (e.g. CNTVOFF).

Thanks,
Mark.
