Generally spoken, yes it is supposed to work, but hardly depends on the hardware platform. I can imagine that it is needed to configure additional TrustZone aware peripherals, e.g. memory controller to enable normal world access. That hardly depends on the hardware and its default values. You might have a look at the EL3 firmware (probably ARM Trusted Firmware), which is loaded via u-boot, what else it does configure beside the CPU registers we're touching in `prepare_non_secure_world`. The real hardware we're using typically prepares EL3 mode via u-boot too. But under Qemu / Raspberry Pi3 we boot through EL3.
