2015-11-10Various Makefiles: Add SPDX-License-Identifier tagsTom Rini
After consulting with some of the SPDX team, the conclusion is that Makefiles are worth adding SPDX-License-Identifier tags too, and most of ours have one. This adds tags to ones that lack them and converts a few that had full (or in one case, very partial) license blobs into the equivalent tag.

2014-07-18yaffs2: preprocessor cleanupJeroen Hofstee
Current code uses the preprocessor to change an else case to a statement without any if condition at all. Although this works, change the optional code to return early, so all optional code is contained within a single #ifdef. Signed-off-by: Jeroen Hofstee <jeroen@myspectrum.nl>
2014-07-18yaffs2: cosmetic: remove self assignmentsJeroen Hofstee
Remove self assignments which is just dead code to prevent compiler warnings about non used arguments. For u-boot this does not prevent any warning though, on the contrary it actual introduces warnings when compiling with clang. Remove them. 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.

2014-01-20yaffs2: Remove block number check from summary verificationCharles Manning

2013-05-31mtd: resync with Linux-3.7.1Sergey Lapin
This patch is essentially an update of u-boot MTD subsystem to the state of Linux-3.7.1 with exclusion of some bits: - the update is concentrated on NAND, no onenand or CFI/NOR/SPI flashes interfaces are updated EXCEPT for API changes. - new large NAND chips support is there, though some updates have got in Linux-3.8.-rc1, (which will follow on top of this patch). To produce this update I used tag v3.7.1 of linux-stable repository. The update was made using application of relevant patches, with changes relevant to U-Boot-only stuff sticked together to keep bisectability. Then all changes were grouped together to this patch.

2012-11-04include/linux/byteorder: import latest endian definitions from linuxKim Phillips
u-boot's byteorder headers did not contain endianness attributions for use with sparse, causing a lot of false positives. Import the kernel's latest definitions, and enable them by including compiler.h and types.h. They come with 'const' added for some swab functions, so fix those up, too: include/linux/byteorder/big_endian.h:46:2: warning: passing argument 1 of '__swab64p' discards 'const' qualifier from pointer target type [enabled by default] Also, note: u-boot's historic __BYTE_ORDER definition has been preserved (for the time being at least). We also remove ad-hoc barrier() definitions, since we're including compiler.h in files that hadn't in the past: macb.c:54:0: warning: "barrier" redefined [enabled by default] In addition, including compiler.h in byteorder changes the 'noinline' definition to expand to __attribute__((noinline)).

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>
2008-08-21Make the YAFFS filesystem workRemy Bohmer
Recently the YAFFS filesystem support has been added to U-boot. However, just enabling CONFIG_YAFFS2 is not enough to get it working. ymount will generate an exception (when dereferencing mtd->readoob()), because the genericDevice is a null pointer. Further, a lot of logging is produced while using YAFFS fs, so logging should also be disabled. Both issues are solved by this patch. With this patch and CONFIG_YAFFS2 enabled, I get a readable filesystem in U-boot, as well as in Linux. Tested on a Atmel AT91SAM9261EK board.
