Hi York,
Sorry, I didn't touch the PSCI in u-boot and what works the PPA is doing, I just work on integrating PPA to u-boot.
Hi Rod and Chenhui,
Can you help to answer the questions about the PSCI and PPA?

The FSL Primary Protected Application (PPA) is a software component loaded during boot which runs in TrustZone and remains resident after boot.

I presume PSCI is implemented in PPA. How does the SMP boot flow change with PPA? U-boot has to remain functional in the absence of PPA, right?
Would it be possible to write a readme for PPA?
Thanks, Zhiqiang
