From: John Crispin <john@phrozen.org> EN7523 is an armv8 based silicon used inside broadband access type devices such as xPON and xDSL. It shares various silicon blocks with MediaTek silicon such as the MT7622.

Is this really needed? TBH I'd be rather surprised to see IOMMUs in a small-scale embedded router SoC, or are there others in a similar vein to MT7623N with random multimedia bits thrown in as well?

This does nothing (except bloat your image with some dead code which won't be called). Robin.
