Sorry, I didn't reply to this part earlier.

If you have a TianoCore port, using that is almost always a better idea. 
I'd compare it to wine vs native Windows. With native Windows, you get 
guaranteed compatibility, wine only tries really hard :).

However, if you compare the size of this patch set to a TianoCore port, 
the rationale becomes pretty clear I guess. Porting a system that is 
already U-Boot enabled to be RTS enabled is a matter of a day of work. 
Non-RTS EFI enablement comes for free in U-Boot.

Porting TianoCore to a new platform takes slightly longer. And you have 
to embrace CamelCase.
