Could you comment on the motivation to also support the non-trusted
boot chain? ST is no longer supporting the non-trusted configuration.
Of course, while we don't have to strictly follow vendor-defined
rules/decision, there's the question of what is the benefit of the
non-trusted version, and if it's worth the effort having support for
both configurations as Buildroot defconfigs.
