Hmm so the EDAC driver only works on DT-based systems?  It feels strange
to me.  AFAIK the ECC memory is mostly used in servers where the
firmware passes ACPI system tables instead of DT.

And it makes the incorrect "select EDAC" (I've mentioned in another
reply) worse: all desktop/server users are now building some code
definitely useless on their systems.
