Very real. It's actually on my desk and I'm not in Matrix :-)
Has no PSCI support. Would be honestly very great. As we (as company)
write the firmware could be technically doable. There is no plan. This
piece of software is meant to bring the CPU from Secure mode to
Unsecure Hypervisor mode before calling kernel/hypervisor code and
provide supervisor calls.

There are documentation in the Linaro kernel, see
I hope it will be merged soon.
