Makefile: Fix build with USE_PRIVATE_LIBGCC

2010-11-18T08:47:11Z

If USE_PRIVATE_LIBGCC is set the yes building fails with a missing libgcc.a As we use partial linking now it is libgcc.o now. Signed-off-by: Matthias Weisser

Switch from archive libraries to partial linking

2010-11-17T20:02:18Z

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. Signed-off-by: Sebastien Carlier

Drop support for CONFIG_SKIP_RELOCATE_UBOOT

2010-10-29T19:40:08Z

For ARM systems, before ELF relocation was introduced, CONFIG_SKIP_RELOCATE_UBOOT coul be used to prevent *COPYING* the U-Boot image from whereever it was loaded to it's link address (CONFIG_SYS_TEXT_BASE). The name was badly chosen, as no relocation was performed at all, it was just a memcpy(). With ELF relocation, this does not work like that any more, and related boards need to be fixed anyway. So don't keep this relict any longer. Signed-off-by: Wolfgang Denk Tested-by: Heiko Schocher Tested-by: Reinhard Meyer

kirkwood: get rid of config.mk files

2010-10-28T13:42:06Z

After moving the definition of CONFIG_SYS_TEXT_BASE to the respective board config files, all Marvell kirkwood board have just a single and common entry in their config.mk files: KWD_CONFIG = $(SRCTREE)/board/$(BOARDDIR)/kwbimage.cfg Replace the only reference to KWD_CONFIG in the top level Makefile by an equivalent setting, and remove all kirkwood config.mk files.

include/asm-offsets.h: automatically generate assembler constants

2010-10-26T19:04:34Z

A recurrent issue is that certain C level constructs like sizeof() or offsetof() cannot be used in assembler files, which is inconvenient when such constructs are used in the definition of macro names etc. To avoid duplication of such definitions (and thus another cause of problems), we adapt the Linux way to automatically generate the respective definitions from the respective C header files. In Linux, this is implemented in include/linux/kbuild.h, Kbuild, and arch/*/kernel/asm-offsets.c; we adapt the code from the Linux v2.6.36 kernel tree. We also copy the concept of the include/generated/ directory which can be used to hold other automatically generated files as well. We start with an architecture-independent lib/asm-offsets.c which generates include/generated/generic-asm-offsets.h (included by include/asm-offsets.h, which is what will be referred to in the actual source code). Later this may be extended by architecture-specific arch/*/lib/asm-offsets.c files that will generate a include/generated/asm-offsets.h. Signed-off-by: Wolfgang Denk Acked-by: Kumar Gala
