PS1, Line 11: static files that are not intended to be updated to the RW regions.
> The other components, like romstage and ramstage, can still be updated when needed by putting them in the RW region. (If it's there the RO copy won't be used).

vboot has tried something in that flavor - please look for RO_NORMAL preamble, although I'm not sure if it's still working today.

Even if not using RO_NORMAL, given you're targeting stage files, I think you should change where the stage files were loaded and add a fallback  when some config is set?
