from my point of view, 32bit platfor= m is not a big problem.

My roadmap of similar project is to port fbsd to stm32mp1 (booting is done, while mounting root requires SD driver, which I decided to leave in secure TZ, rewriting fsbl for that reason) and expose SD to the kernel as a trivial char device (may be some kernel glue).

As for the video, I chosen DSI interface, but have not tested custom screen I ordered for it yet. At least I hope to create kind of "suppported" hardware environment to be able to boot FBDS, Linux, etc.

So, I see no problems using 32bit as= playground. Familiarizing myself with some aspects of fsbl/tz/power management and then go further to stm32mp2, which may become a 10+ years old smartphone with FBSD targeted towards security, modularity, openness.
