Hi Rod and Chenhui,
Can you help to answer the questions about PSCI?

The FSL Primary Protected Application (PPA) is a software component loaded during boot which runs in TrustZone and remains resident after boot.
Signed-off-by: Hou Zhiqiang Zhiqiang.Hou@freescale.com
Tested on LS1043A RDB board
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?
Also, how does the devicetree get updated to indicate the presence of PSCI?
Thanks, Zhiqiang
