I'm afraid you're barking up the wrong tree.
TI, in its infinite wisdom, drops directly to *non-secure*. So, there is
nothing you can actually do (maybe there's a way to go back to secure
mode, but that's certainly not documented).
The consequence of the above is that you cannot implement PSCI on
OMAP4/5. You'll have to add you own code to promote your CPUs to HYP
(there is a secure call for this).
Good luck,
M.
