I can also try it on a SAMA5D3 (I don't have a SAMA5D4 with me at > the moment), tough, just to be sure nothing is broken there too. That doesn't answer my question. I asked if there were any systems which might be affected by your patch, and you listed a bunch of systems that _aren't_ affected (that is, they continue to work properly). What systems might run into trouble with this patch?
