Subject: [Tee-dev] OPtee Porting.
 

Hi tee-dev experts,


I am trying to port optee to our custom arm platform.I have gone through some documents but i didn't get a clear picture on this. I have some concerns like below to clarify:


  1. Is  arm-trusted firmware really required in the optee bringup?
  2. Can we boot optee directly from u-boot without arm-trusted firmware?
  3. Is there any good documentation for optee porting for custom arm soc?
  4. Is there any specific hardware requirements to run optee?
  5. Can you please share me , if anybody have boot flow of optee?



I appreciate your comments.


Thanks in advance.
