* Kbuild: introduce Makefile in arch/$ARCH/Daniel Schwierzeck2014-12-08-22/+1
| | | | | | | | | | | | | | | Introduce a Makefile under arch/$ARCH/ and include it in the top Makefile (similar to Linux kernel). This allows further refactoringi like moving architecture-specific code out of global makefiles, deprecating config variables (CPU, CPUDIR, SOC) or deprecating arch/$ARCH/config.mk. In contrary to Linux kernel, U-Boot defines the ARCH variable by Kconfig, thus the arch Makefile can only included conditionally after the top config.mk.

Otherwise, the SPL image is not built at all. Having "spl/.config" makes no sense.

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* kconfig: switch to KconfigMasahiro Yamada2014-07-30-50/+538
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* scripts: add scripts/show-gnu-make to get GNU Make command nameMasahiro Yamada2014-07-29-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | 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. They should call this helper script and get the command name for GNU Make. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* scripts: add mailmapper, a tool to create/update mailmap fileMasahiro Yamada2014-07-22-0/+160
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | Linux supports this, and if we are to have compatible device tree files, U-Boot should also. Avoid giving the device tree files access to U-Boot's include/ directory. Only include/dt-bindings is accessible.
