We have similar "designs" already :)

Memory controller driver drivers/edac/fsl_ddr_edac.c gets linked together with:

mpc85xx_edac_mod-y                      := fsl_ddr_edac.o mpc85xx_edac.o
obj-$(CONFIG_EDAC_MPC85XX)              += mpc85xx_edac_mod.o

layerscape_edac_mod-y                   := fsl_ddr_edac.o layerscape_edac.o
obj-$(CONFIG_EDAC_LAYERSCAPE)           += layerscape_edac_mod.o
