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 -- Regards/Gruss, Boris.
