Can we add something to the top level Makefile like the following:
MPC8641HPCN_36BIT_config \
MPC8641HPCN_config: unconfig
@mkdir -p $(obj)include
@if [ "$(findstring _36BIT_,$@)" ] ; then \
$(XECHO) -n "... I Rock " ; \
echo "#define CONFIG_PHYS_64BIT" >>$(obj)include/
config.h ;\
fi ;
@$(MKCONFIG) -a MPC8641HPCN ppc mpc86xx mpc8641hpcn freescale
(also add this to MAKEALL)
The name could be better.
