As I see it this patchset seeks to provide (and does a good job of it)
you with PSCI services on platforms where you don't already have this,
so you avoid having to implement yet another platform-specific SMP
boot-up sequence in the kernel. This is not about providing any generic
support for secure firmware.
Ideally, the platform would just ship with PSCI support and boot U-Boot
in Hyp mode and everyone would be happy - whichever way vendors wish to
do that is a completely different discussion than this patch set.
