Yes, there is indeed this problem with the pen. Maybe one can use your upcoming relocation code to move the pen to a more secure place (defined per platform).
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...).
With "avoid dealing with a pen" you mean to wakeup from the system's pen and immediately jump to the OS init code, without staying in a wfi loop in some special memory?
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.
