i'm feeling particularly stupid today in not understanding some of
the things i'm running across. just tripped over this in
board/spear/common/Makefile:
...
ifdef CONFIG_SPL_BUILD
# necessary to create built-in.o
obj- := __dummy__.o <--- ??????
else
...
i've never seen that syntax before, and there's just a bit of it in
the entire tree:
$ grep -r "obj- " *
arch/arm/cpu/arm1176/Makefile:obj- += dummy.o
arch/arm/cpu/Makefile:obj- += dummy.o
board/samsung/smdkv310/Makefile:obj- := __dummy__.o
board/samsung/origen/Makefile:obj- := __dummy__.o
board/spear/x600/Makefile:obj- := __dummy__.o
board/spear/common/Makefile:obj- := __dummy__.o
board/freescale/common/Makefile:obj- := __dummy__.o
board/varisys/common/Makefile:obj- := __dummy__.o
$
what does that mean?
