That's not correct. There's a bunch of features that are broken
without A64-specific (or at least not present on the A13)
quirks. Those features include for example the SDIO aggregation that
are currently broken for all modes supported so far.

I was in holidays and send those patches tomorrow, but you were a bit
too quick :)
