Switch from archive libraries to partial linking Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

Build arch/$ARCH/lib/bootm.o depending on CONFIG_CMD_BOOTM MAKEALL is fine for ppc4xx and mpc85xx. Run checks were done on our controlcenterd hardware.

sparc: fix a link error Before this commit, arch/sparc/lib/Makefile used both COBJS and COBJS-y. And it missed to add COBJS-y into OBJS. This means bootm.o was never compiled even if CONFIG_CMD_BOOTM=y Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Cc: Daniel Hellstrom <daniel@gaisler.com> 2013-10-21 02:53:24 +00:00			`COBJS := $(COBJS) $(COBJS-y)`

Big white-space cleanup. This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de> 2008-05-20 14:00:29 +00:00			`SRCS := $(SOBJS:.o=.S) $(COBJS:.o=.c)`
