Masahiro Yamada 3d8256b2a1 Use #ifdef for IMAGE_BL* instead of #if ... One nasty part of ATF is some of boolean macros are always defined as 1 or 0, and the rest of them are only defined under certain conditions. For the former group, "#if FOO" or "#if !FOO" must be used because "#ifdef FOO" is always true. (Options passed by $(call add_define,) are the cases.) For the latter, "#ifdef FOO" or "#ifndef FOO" should be used because checking the value of an undefined macro is strange. Here, IMAGE_BL* is handled by make_helpers/build_macro.mk like follows: $(eval IMAGE := IMAGE_BL$(call uppercase,$(3))) $(OBJ): $(2) @echo " CC $$<" $$(Q)$$(CC) $$(TF_CFLAGS) $$(CFLAGS) -D$(IMAGE) -c $$< -o $$@ This means, IMAGE_BL* is defined when building the corresponding image, but *undefined* for the other images. So, IMAGE_BL* belongs to the latter group where we should use #ifdef or #ifndef. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>		2017-01-24 01:01:21 +09:00
