Dear all,

        I have some questions about u-boot Makefile.

        Could you help me ?

        Thx!

        The below is my question.

        First, we do make _depend for those $(SUBDIRS) $(CPUDIR)
$(LDSCRIPT_MAKEFILE_DIR)

        depend dep:     $(TIMESTAMP_FILE) $(VERSION_FILE) \
                $(obj)include/autoconf.mk \
                $(obj)include/generated/generic-asm-offsets.h \
                $(obj)include/generated/asm-offsets.h
                for dir in $(SUBDIRS) $(CPUDIR) $(LDSCRIPT_MAKEFILE_DIR) ;
do \
                        $(MAKE) -C $$dir _depend ; done

        after we already generated the .depend file in those dirs.

        $(SUBDIRS):     depend
                $(MAKE) -C $@ all

        That would do make action in SUBDIRS dir.
        But why we also sinclude .depend in those Makefile which is base on
those dir ? I regard that we already generated before.

        And another questions, how does the other sub-dir(eg, libs) .depend
file generated ? is that generated by rules.mk which is include every
sub-dirs?


Best regards
