If that's your primary concern, then in the short term, how about just
sending a single-line patch to the arch/riscv/mm Makefile to skip building
it if !CONFIG_SOC_SIFIVE? Assuming, that is, you won't be enabling EDAC
support for those low-end SoCs. Then you won't need to get the ack
from the EDAC folks in the short term.

Then a patch to make the SiFive platform EDAC driver build contingent on
CONFIG_SOC_SIFIVE could be sent separately.
