I don't think that's an good idea. You most likely need that because you
have downstream bootloader installed on this board. PSCI implementation
takes place in TEE-OS for Rockchips ARM SoCs. There is no support for
RK3036 in upstream op-tee OS. It's pretty much the same for RK3128 and
RK3288.
If you use upstream u-boot it should be good as-is.
