You're missing that part of the quote:

"...code a driver that scans the connected memories in order to register
its child devices for each of the subsystems."

If you can do that, then I'd take that patch to the MFD subsystem. Otherwise,
the only incentive for me to take it would be to be able to share the 2
functions currently in this driver between several archs. But MFD would just
be a placeholder for this driver right now.

Cheers,
Samuel.
