of course, arm had to invent their own wheel, many wheels, and give them weird names, a lot of them, the whole hyerarchy. 
but with respect to UEFI, all that pre-pre-init "teh security" thing is a SEC phase, which hands control off to the UEFI.
You actually double my question, because it's either UEFI or uboot or whateverboot, but not all together.
because whereas all those secure world blobs do is that "they are signed, trusted, yay!", UEFI or uboot do the real initialization work, choose an OS to boot, interact with a user to let them brick configure the boot option and board etc.
