Yes, that's what I've done. Also rewritten some of it to be able to
execute solely in secure mode (you can't do SMC+HVC there, as you'd try
to run non-secure from secure RAM...).

Even better, waking up the CPUs from power-off directly, configuring the
per-cpu part of the GIC and jumping to the kernel. Almost nothing.
