2014-06-11LzmaTools: don't self assign valuesJeroen Hofstee
It seems the code tries to trick the compiler the argument is actually used. However compilers became too smart to fool them so easily an now warn. Gcc and clang don't seem to emit a warning when the argument is unused. If so it should be decorated with unused / (void). Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>
2014-02-19kbuild: use Linux Kernel build scriptsMasahiro Yamada
Now we are ready to switch over to real Kbuild. This commit disables temporary scripts: scripts/{Makefile.build.tmp, Makefile.host.tmp} and enables real Kbuild scripts: scripts/{Makefile.build,Makefile.host,Makefile.lib}. This switch is triggered by the line in scripts/Kbuild.include -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj We need to adjust some build scripts for U-Boot. But smaller amount of modification is preferable. Additionally, we need to fix compiler flags which are locally added or removed. In Kbuild, it is not allowed to change CFLAGS locally. Instead, ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o are prepared for that purpose.

2014-01-14lzma: fix buffer bound check errorAntonios Vamporakis
Variable uncompressedSize references the space available, while outSizeFull is the actual expected uncompressed size. Using the wrong value causes LzmaDecode to return SZ_ERROR_INPUT_EOF. Problem was introduced in commit afca294. While at it add additional debug message.

2013-09-03lzma: correctly bounds-check output bufferKees Cook
The output buffer size must be correctly passed to the lzma decoder or there is a risk of overflowing memory during decompression. Switching to the LZMA_FINISH_END mode means nothing is left in an unknown state once the buffer becomes full. Signed-off-by: Kees Cook <keescook@chromium.org> Acked-by: Simon Glass <sjg@chromium.org>

2012-12-06lzma: update to lzma sdk 9.20Stefan Reinauer
Updated code taken from latest lzma sdk release 9.20 at http://downloads.sourceforge.net/sevenzip/lzma920.tar.bz2 This generates quite a lot of checkpatch warnings, but I guess we need to keep the code style as is to avoid a massive job each time we update this.

2011-08-04Convert ISO-8859 files to UTF-8Albert ARIBAUD
There was a mix of UTF-8 and ISO-8859 files in the U-Boot source tree, which could cause issues with the patchwork review system. This commit converts all ISO-8859 files to UTF-8. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>
2010-11-17Switch from archive libraries to partial linkingSebastien Carlier
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>

Now that the other architecture-specific lib directories have been moved out of the top-level directory there's not much reason to have the '_generic' suffix on the common lib directory. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
