+"""
+A wrapper script to adjust Kconfig for U-Boot
+
+The biggest difference between Linux Kernel and U-Boot in terms of the
+board configuration is that U-Boot has to configure multiple boot images
+per board: Normal, SPL, TPL.
+We need to expand the functions of Kconfig to handle multiple boot
+images.
+
+Instead of touching various parts under the scripts/kconfig/ directory,
+pushing necessary adjustments into this single script would be better
+for code maintainance. All the make targets related to the configuration
+(make %config) should be invoked via this script.
+
+Let's see what is different from the original Kconfig.
+
+- config, menuconfig, etc.
+
+The commands 'make config', 'make menuconfig', etc. are used to create
+or modify the .config file, which stores configs for Normal boot image.
+
+The location of the one for SPL, TPL image is spl/.config, tpl/.config,
+respectively. Use 'make spl/config', 'make spl/menuconfig', etc.
+to create or modify the spl/.config file, which contains configs
+for SPL image.
+Do likewise for the tpl/.config file.
+The generic syntax for SPL, TPL configuration is
+'make <target_image>/<config_command>'.
+
+- silentoldconfig
+
+The command 'make silentoldconfig' updates .config, if necessary, and
+additionally updates include/generated/autoconf.h and files under
+include/configs/ directory. In U-Boot, it should do the same things for
+SPL, TPL images for boards supporting them.
+Depending on whether CONFIG_SPL, CONFIG_TPL is defined or not,
+'make silentoldconfig' iterates three times at most changing the target
+directory.
+
+To sum up, 'make silentoldconfig' possibly updates
+ - .config, include/generated/autoconf.h, include/config/*
+ - spl/.config, spl/include/generated/autoconf.h, spl/include/config/*
+ (in case CONFIG_SPL=y)
+ - tpl/.config, tpl/include/generated/autoconf.h, tpl/include/config/*
+ (in case CONFIG_TPL=y)
+
+- defconfig, <board>_defconfig
+
+The command 'make <board>_defconfig' creates a new .config based on the
+file configs/<board>_defconfig. The command 'make defconfig' is the same
+but the difference is it uses the file specified with KBUILD_DEFCONFIG
+environment.
+
+We need to create .config, spl/.config, tpl/.config for boards where SPL
+and TPL images are supported. One possible solution for that is to have
+multiple defconfig files per board, but it would produce duplication
+among the defconfigs.
+The approach chosen here is to expand the feature and support
+conditional definition in defconfig, that is, each line in defconfig
+files has the form of:
+<condition>:<macro definition>
+
+The '<condition>:' prefix specifies which image the line is valid for.
+The '<condition>:' is one of:
+ None - the line is valid only for Normal image
+ S: - the line is valid only for SPL image
+ T: - the line is valid only for TPL image
+ ST: - the line is valid for SPL and TPL images
+ +S: - the line is valid for Normal and SPL images
+ +T: - the line is valid for Normal and TPL images
+ +ST: - the line is valid for Normal, SPL and SPL images
+
+So, if neither CONFIG_SPL nor CONFIG_TPL is defined, the defconfig file
+has no '<condition>:' part and therefore has the same form of that of
+Linux Kernel.
+
+In U-Boot, for example, a defconfig file can be written like this:
+
+ CONFIG_FOO=100
+ S:CONFIG_FOO=200
+ T:CONFIG_FOO=300
+ ST:CONFIG_BAR=y
+ +S:CONFIG_BAZ=y
+ +T:CONFIG_QUX=y
+ +ST:CONFIG_QUUX=y
+
+The defconfig above is parsed by this script and internally divided into
+three temporary defconfig files.
+
+ - Temporary defconfig for Normal image
+ CONFIG_FOO=100
+ CONFIG_BAZ=y
+ CONFIG_QUX=y
+ CONFIG_QUUX=y
+
+ - Temporary defconfig for SPL image
+ CONFIG_FOO=200
+ CONFIG_BAR=y
+ CONFIG_BAZ=y
+ CONFIG_QUUX=y
+
+ - Temporary defconfig for TPL image
+ CONFIG_FOO=300
+ CONFIG_BAR=y
+ CONFIG_QUX=y
+ CONFIG_QUUX=y
+
+They are passed to scripts/kconfig/conf, each is used for generating
+.config, spl/.config, tpl/.config, respectively.
+
+- savedefconfig
+
+This is the reverse operation of 'make defconfig'.
+If neither CONFIG_SPL nor CONFIG_TPL is defined in the .config file,
+it works as 'make savedefconfig' in Linux Kernel: create the minimal set
+of config based on the .config and save it into 'defconfig' file.
+
+If CONFIG_SPL or CONFIG_TPL is defined, the common lines among .config,
+spl/.config, tpl/.config are coalesced together and output to the file
+'defconfig' in the form like:
+
+ CONFIG_FOO=100
+ S:CONFIG_FOO=200
+ T:CONFIG_FOO=300
+ ST:CONFIG_BAR=y
+ +S:CONFIG_BAZ=y
+ +T:CONFIG_QUX=y
+ +ST:CONFIG_QUUX=y
+
+This can be used as an input of 'make <board>_defconfig' command.
