So even the DT-only sub-architecture (such as mvebu) should hard-code
the register base addresses?

The proposed DT binding in the current patch is very minimal, and I
don't see why the more elaborate DT binding that you proposed could not
be implemented as an improvement of it: the DT binding you proposed
seems backward compatible with the one currently implemented, no?

Anyway, whatever your decision is, I can submit an updated patch set
that implements this, and also fix the mv78xx0 patch (my colleague
Gregory Clement found a problem with the mv78xx0 when testing on real
hardware).

Best regards,

Thomas
