I too am unhappy with how some of these have gone. The _intent_ here is
that getting the current "boot generic distro" framework is complex /
error prone, and we can do better. Unfortunately the first set of
platforms to switch to this are Rockchip and I think there was overlap
there with platforms that got broken at the end of the v2023.01 cycle to
fix other platforms, and then those sets of platforms flipped early in
v2023.04 and took until -rc2? to get resolved.  Which was less than
ideal.

I wish I knew where to talk to with ATF / TF-A to get some agreed upon
naming scheme going as one of the things that is very frustrating is
getting the names and combinations of everything else that's required
Just Right for every chip. And feedback that things aren't working is
appreciated, since we do need to make things easier.
