To my very best knowledge I have not seen these WARNINGs in the last
two-ish years.  Hence me asking what changed on FreeBSD that they do show up
now and if we need to do some things connditionally on flags or
otherwise?

Or, given the thought came, if we do now rely on a specific minimum and
that needs to be documented/enforced.

Yeah, this is a u-boot system and I do have access to the TF-A sources
from a public repo but rebasing them will be challenging I bet.
I believe they are based on v1.5 and then updated by manufacturer for years
and provided to vendor who put further fixes on top for various memory
issues for the SoC.

This system of (Linux) embedded people is so unsustainable.  I am tired
of having to do firmware updates and builds for almost every SoC that
goes through my hands these days *sigh*.

I assume I'll have to bite the bullet but I really would love to
understand which chnages on FreeBSD started triggering the WARNINGs.
