Hi,
in past without PMU fw it was possible to run U-Boot in EL3. Firmware changes made ATF required that's why generation was done like this. But some recent changes (especially passing PMUFW object to PMU from SPL) introduce the whole infrastructure for talking to PMU via IPI interface. That's why this interface can be reused and run U-Boot in EL3 again.
Based on it I have fixed mkimage_fit_atf.sh script to generate u-boot.its/itb based on ATF availability but still producing working image without it.
Also found two issues which should be fixed to get U-Boot work in EL3.
Thanks, Michal
