When spl/.config is updated by "make spl/menuconfig" or friends, spl/include/config/auto.conf, spl/include/generated/autoconf.h and some other files must be updated by "make silentoldconfig".

2014-09-16kconfig: add sanity checks for SPL configurationMasahiro Yamada
For the SPL configuration, "make <dir>/<target>" is used. Here, <dir> is either "spl" or "tpl" <target> is one of "config", "menuconfig", "xconfig", etc. This commit adds two checks: [1] If <dir> is given an unsupported subimage, the configuration should error out like this: $ make qpl/menuconfig *** *** "make qpl/menuconfig" is not supported. *** [2] Make sure that "CONFIG_SPL" is enabled in the ".config" before running "make spl/menuconfig. Otherwise, the SPL image is not built at all. Having "spl/.config" makes no sense. In such a case, the configuration should exit with a message: $ make spl/menuconfig *** *** Create ".config" with "CONFIG_SPL" enabled *** before "make spl/menuconfig". *** Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Suggested-by: Simon Glass <sjg@chromium.org>

2014-08-22kconfig: convert Kconfig helper script into a shell scriptMasahiro Yamada
Commit 51148790 added scripts/multiconfig.py written in Python 2 to adjust Kconfig for U-Boot. It has been hard for Python 3 users because Python 2 and Python 3 are not compatible with each other. We are not happy about adding a new host tool dependency (in this case, Python version dependency) for the core build process. After some discussion, we decided to use only basic tools. The script may get a bit more unreadable by shell scripting, but we believe it is worthwhile. In addition, this commit revives "<board>_config" target that is equivalent to "<board>_defconfig" for backwards compatibility. It is annoying to adjust various projects which use U-Boot.

2014-08-21kbuild: sync mixed targets handling with Linux 3.16Masahiro Yamada
"make %_config all" was supported for the first time in U-Boot: commit 53bca5ab kbuild: support simultaneous board configuration and "make all" Surprisingly it had not been working in Linux Kernel for a long time. So I sent back the patch to the Linux Kbuild community and it was accepted with a little code improvement, at commit 9319f453. Now, you can do "make defconfig all" or "make %_defconfig all" in Linux too. This commit updates some scripts to fill the code-diff between Linux and U-Boot.

2014-08-21kbuild: move extra gcc checks to scripts/Makefile.extrawarnMasahiro Yamada
This commit was imported from Linux Kernel: commit a86fe353 written by me. W=... provides extra gcc checks. Having such code in scripts/Makefile.build results in the same flags being added to KBUILD_CFLAGS multiple times becuase scripts/Makefile.build is invoked every time Kbuild descends into the subdirectories. Since the top Makefile is already too cluttered, this commit moves all of extra gcc check stuff to a new file scripts/Makefile.extrawarn, which is included from the top Makefile.

2014-08-21tools, scripts: refactor error-out statements of Python scriptsMasahiro Yamada
In Python, sys.exit() function can also take an object other than an integer. If an integer is given to the argument, Python exits with the return code of it. If a non-integer argument is given, Python outputs it to stderr and exits with the return code of 1. That means, print >> sys.stderr, "Blah Blah" sys.exit(1) is equivalent to sys.exit("Blah Blah") The latter is a useful shorthand. Note: Some error messages in Buildman and Patman were output to stdout. But they should go to stderr. They are also fixed by this commit. This is a nice side effect.

2014-07-30kconfig: switch to KconfigMasahiro Yamada
This commit enables Kconfig. Going forward, we use Kconfig for the board configuration. mkconfig will never be used. Nor will include/config.mk be generated. Kconfig must be adjusted for U-Boot because our situation is a little more complicated than Linux Kernel. We have to generate multiple boot images (Normal, SPL, TPL) from one source tree. Each image needs its own configuration input. Usage: Run "make <board>_defconfig" to do the board configuration. It will create the .config file and additionally spl/.config, tpl/.config if SPL, TPL is enabled, respectively. You can use "make config", "make menuconfig" etc. to create a new .config or modify the existing one. Use "make spl/config", "make spl/menuconfig" etc. for spl/.config and do likewise for tpl/.config file. The generic syntax of configuration targets for SPL, TPL is: <target_image>/<config_command> Here, <target_image> is either 'spl' or 'tpl' <config_command> is 'config', 'menuconfig', 'xconfig', etc. When the configuration is done, run "make". (Or "make <board>_defconfig all" will do the configuration and build in one time.) For futher information of how Kconfig works in U-Boot, please read the comment block of scripts/multiconfig.py. By the way, there is another item worth remarking here: coexistence of Kconfig and board herder files. Prior to Kconfig, we used C headers to define a set of configs. We expect a very long term to migrate from C headers to Kconfig. Two different infractructure must coexist in the interim. In our former configuration scheme, include/autoconf.mk was generated for use in makefiles. It is still generated under include/, spl/include/, tpl/include/ directory for the Normal, SPL, TPL image, respectively.

2014-07-29scripts: add scripts/show-gnu-make to get GNU Make command nameMasahiro Yamada
U-Boot is expected to be built on various platforms. We should keep in mind that the command 'make' is not always GNU Make, while all the makefiles are written for GNU Make. For example, on Linux, people generally do: make <board>_config; make But FreeBSD folks do gmake <board>_config; gmake (The command 'make' on FreeBSD is BSD Make, not GNU Make) It is not a good idea to hard-code the command name 'make' in MAKEALL or buildman.

2014-07-22scripts: add mailmapper, a tool to create/update mailmap fileMasahiro Yamada
This tool helps to create/update the mailmap file. It runs 'git shortlog' internally and searches differently spelled author names which share the same email address. The author name with the most commits is asuumed to be a canonical real name. If the number of commits from the cananonical name is equal to or greater than 'MIN_COMMITS' (=50), the entry for the cananical name will be output. ('MIN_COMMITS' is used here because we do not want to create a fat mailmap by adding every author with only a few commits.) If there exists a mailmap file specified by the mailmap.file configuration options or '.mailmap' at the toplevel of the repository, it is used as a base file. The base file and the newly added entries are merged together and sorted alphabetically (but the comment block is kept untouched), and then printed to standard output. Usage ----- scripts/mailmapper prints the mailmapping to standard output. scripts/mailmapper > tmp; mv tmp .mailmap will be useful for updating '.mailmap' file.

2014-03-07kbuild: improve Kbuild speedMasahiro Yamada
Kbuild brought about many advantages for us but a significant performance regression was reported by Simon Glass. After some discussions and analysis, it turned out its main cause is in $(call cc-option,...). Historically, U-Boot parses all config.mk (arch/*/config.mk and board/*/config.mk) every time descending into subdirectories. That means cc-options are evaluated over and over again. $(call cc-option,...) is useful but costly. So we want to evaluate them only in ./Makefile and spl/Makefile and export compiler flags. This commit changes the build system as follows: - Modify scripts/Makefile.build to not include config.mk Instead, add $(PLATFORM_CPPFLAGS) to asflags-y, ccflags-y, cppflags-y. - Export many variables Going forward, Kbuild will not parse config.mk files when it descends into subdirectories. If we want to set variables in config.mk and use them in subdirectories, they must be exported. This is the list of variables to get exported: PLATFORM_CPPFLAGS CPUDIR BOARDDIR OBJCOPYFLAGS LDFLAGS LDFLAGS_FINAL (used in nand_spl/board/*/*/Makefile) CONFIG_STANDALONE_LOAD_ADDR (used in examples/standalone/Makefile) SYM_PREFIX (used in examples/standalone/Makefile) RELFLAGS (used in examples/standalone/Makefile) - Delete CPPFLAGS This variable has been replaced with PLATFORM_CPPFLAGS - Copy gcclibdir from example/standalone/Makefile to arch/sparc/config.mk The reference in CONFIG_STANDALONE_LOAD_ADDR must be resolved before it is exported.

2014-03-04scripts: update checkpatch.pl to latest upstream versionTom Rini
Update to v3.14-rc4's version of checkpatch.pl. In doing so we drop the changes to top_of_kernel_tree() as we pass in --no-tree and drop our changes about MAINTAINERS as that's for reporting checkpatch.pl problems itself (and upstream has said they'll reword this section to be clearer).
