Hi Simon, It is a good suggestion. But device tree is board specific, while the config is boot flow specific. For ATF -> OPTEE -> U-BOOT case, initialization should be skipped. Without earlier initialization from firmware, U-boot should do it by itself. So I need find a solution that is defconfig specific, instead of device tree specific. Regards.
