	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.

2014-08-21	tools, scripts: refactor error-out statements of Python scripts	Masahiro 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.

2014-07-30	kconfig: switch to Kconfig	Masahiro 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.
