* punt unused clean/distclean targetsMike Frysinger2011-10-15-6/+0
| | | | | | | | | | The top level Makefile does not do any recursion into subdirs when cleaning, so these clean/distclean targets in random arch/board dirs never get used. Punt them all. MAKEALL didn't report any errors related to this that I could see. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <sebastien.carlier@gmail.com>
* Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk2010-10-18-1/+1
| | | | | | | | | | | | The change is currently needed to be able to remove the board configuration scripting from the top level Makefile and replace it by a simple, table driven script. Moving this configuration setting into the "CONFIG_*" name space is also desirable because it is needed if we ever should move forward to a Kconfig driven configuration system.

* Fix all linker script to handle all rodata sectionsTrent Piepho2009-03-20-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A recent gcc added a new unaligned rodata section called '.rodata.str1.1', which needs to be added the the linker script. Instead of just adding this one section, we use a wildcard ".rodata*" to get all rodata linker section gcc has now and might add in the future. However, '*(.rodata*)' by itself will result in sub-optimal section ordering. The sections will be sorted by object file, which causes extra padding between the unaligned rodata.str.1.1 of one object file and the aligned rodata of the next object file. This is easy to fix by using the SORT_BY_ALIGNMENT command. This patch has not be tested one most of the boards modified. Some boards have a linker script that looks something like this: *(.text) . = ALIGN(16); *(.rodata) *(.rodata.str1.4) *(.eh_frame) I change this to: *(.text) . = ALIGN(16); *(.eh_frame) *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*))) This means the start of rodata will no longer be 16 bytes aligned. However, the boundary between text and rodata/eh_frame is still aligned to 16 bytes, which is what I think the real purpose of the ALIGN call is. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>

* Fix linker scripts: add NOLOAD atribute to .bss/.sbss sectionsWolfgang Denk2008-01-12-1/+1
| | | | | | | | | | | | | | | | | | | With recent toolchain versions, some boards would not build because or errors like this one (here for ocotea board when building with ELDK 4.2 beta): ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab] For many boards, the .bss section is big enough that it wraps around at the end of the address space (0xFFFFFFFF), so the problem will not be visible unless you use a 64 bit tool chain for development. On some boards however, changes to the code size (due to different optimizations) we bail out with section overlaps like above. The fix is to add the NOLOAD attribute to the .bss and .sbss sections, telling the linker that .bss does not consume any space in the image. Signed-off-by: Wolfgang Denk <wd@denx.de>
