Hi Wolfgang,
How do you think of this method? Or can we handle the different options
as follows?
MPC8536DS_NAND_config: unconfig
@echo "" >$(obj)include/config.h;
@echo "#define CONFIG_$(subst MPC8536DS_,,$(subst
config,U_BOOT,$@))" \
> $(obj)include/config.h
@$(MKCONFIG) -a MPC8536DS ppc mpc85xx mpc8536ds freescale
@echo "CONFIG_$(subst MPC8536DS_,,$(subst config,U_BOOT,$@)) = y"
\
>> $(obj)include/config.mk
If there's an orthogonal option, such as 36BIT, we have to handle it
seperately:
MPC8536DS_NAND_config \
MPC8536DS_NAND_36BIT_config: unconfig
@echo "" >$(obj)include/config.h;
@if [ "$(findstring _36BIT_,$@" ] ; then \
echo "#define CONFIG_PHYS_64BIT" >>$(obj)include/config.h
; \
fi
@echo "#define CONFIG_$(subst MPC8536DS_,,$(subst
config,U_BOOT,$@))" \
> $(obj)include/config.h
@$(MKCONFIG) -a MPC8536DS ppc mpc85xx mpc8536ds freescale
@echo "CONFIG_$(subst MPC8536DS_,,$(subst config,U_BOOT,$@)) = y"
\
>> $(obj)include/config.mk
Look forward to your comments.
Thanks,
