Yes, this essentially what I suggested in the thread (and my last reply)
and relying on syscon rather than a custom driver seems like a good
idea. It would allow early access to the registers too with the recently
proposed changes. It would not guarantee any kind of exclusivity,
though, but I guess that's tolerable?

I know about the "mfd: syscon: Decouple syscon interface from platform
devices" series, but I wonder why we would need to access GPBR
registers during early boot stages. Do you have something in mind :-)?

Yeah, that's what I was referring to. In the thread from last year,
Jean-Christophe mentioned something about barebox using the
backup-registers. Not sure about the details, though.
