TDA4VM: Whether uboot-spl can use optee services

Hi,

We have not validated this on SPL. There is R5 SPL and A72 SPL. Which one is accessing the OPTEE services?

- Keerthy

hi

Because we want to verify uboot, we choose A72 SPL

HI 

OPTEE services at  UBOOT  stage is not supported currently.If you want to authenticate the u-boot image it is already implemented inside A72 SPL by making use of TISCI_MSG_PROC_AUTH_BOOT TISCI api 

Regards
Diwakar

hi

1.Does the TISCI_MSG_PROC_AUTH_BOOT command work in the GP chip?

2.We came up with a more suitable way to boot uboot directly through ATF instead of uboot-spl, In this case, we only need to verify the uboot in the SBL, Therefore, we would like to ask how ATF can modify to directly start uboot
