Hi,
I am trying to implement TEE and support Linux power features.
There are several options to include power features and TEE
ATFW for ARM32.
Develop runtime service code in U-Boot like ATFW.
Integrate PSCI ARM32 in OP-TEE.
Option1, ATFW seems not support ARM32, such as A9/A7. And the AArch32
support, I think(not sure), is not for legacy ARM32 cores.
Indeed it seems that the main focus is ARMv8-A. FYI, the presentation made by ARM at Linaro Connect is at http://connect.linaro.org/resource/las16/las16-402/.
