So?

You don't have to do those funny games in the Makefile. Instead, you
have your main CONFIG_EDAC_ALTERA_MC option and all the other CONFIG_*
options depend on it. The ifdeffery in altera_edac.c then takes care of
what needs to be enabled or not.

However(!), your driver is not huge or something. So I still don't
understand why you need that split and those additional config options
and why not keep it all together in one file. What is the compelling use
case for that split and additional complexity?

I should've nacked that split at the time.
