So it turned out that what I last tried with R28.3.0 was downstream
U-Boot plus upstream TF-A v2.1. I've been digging into this and have a
draft fix for upstream TF-A, a BL2 parameter layout change:


With this I can boot into -rc4 on R28.3.0. Haven't re-checked R24 yet.

Some U-Boot side EFI and non-EFI problems (as well as kernel deferred
probing problems) remain to be investigated.
