To simplify the top level makefile it useful to be able to set some #defines in config.h to express different configurations.
Added a -D option that allows us to replace:
MPC8536DS_36BIT_config \ MPC8536DS_config: unconfig @mkdir -p $(obj)include @echo "#define CONFIG_$(@:_config=) 1" >$(obj)include/config.h @$(MKCONFIG) -a MPC8536DS ppc mpc85xx mpc8536ds freescale
with:
MPC8536DS_36BIT_config \ MPC8536DS_config: unconfig @$(MKCONFIG) -D $(@:_config=)=1 MPC8536DS ppc mpc85xx mpc8536ds freescale
