In some scenarios, there is a lot more that could need to be done however: - Access to eMMC RPMB memory - Access to keys stored in OP-TEE, e.g. in Trusted Keys TA or in fTPM - Access to hardware managed by OP-TEE via e.g. PRNG TA Let's prepare for all that by importing the Linux v6.6 OP-TEE support into barebox. This series has been tested on STM3MP15 and STM32MP13 32-bit ARM SoCs, where OP-TEE functioned as SCMI provider, restricting access to some clocks, resets and regulators deemed too important to let pesky normal world have direct access to them.
