+Move config options from headers to defconfig files.
+
+Since Kconfig was introduced to U-Boot, we have worked on moving
+config options from headers to Kconfig (defconfig).
+
+This tool intends to help this tremendous work.
+
+
+Usage
+-----
+
+This tool takes one input file. (let's say 'recipe' file here.)
+The recipe describes the list of config options you want to move.
+Each line takes the form:
+<config_name> <type> <default>
+(the fields must be separated with whitespaces.)
+
+<config_name> is the name of config option.
+
+<type> is the type of the option. It must be one of bool, tristate,
+string, int, and hex.
+
+<default> is the default value of the option. It must be appropriate
+value corresponding to the option type. It must be either y or n for
+the bool type. Tristate options can also take m (although U-Boot has
+not supported the module feature).
+
+You can add two or more lines in the recipe file, so you can move
+multiple options at once.
+
+Let's say, for example, you want to move CONFIG_CMD_USB and
+CONFIG_SYS_TEXT_BASE.
+
+The type should be bool, hex, respectively. So, the recipe file
+should look like this:
+
+ $ cat recipe
+ CONFIG_CMD_USB bool n
+ CONFIG_SYS_TEXT_BASE hex 0x00000000
+
+And then run this tool giving the file name of the recipe
+
+ $ tools/moveconfig.py recipe
+
+The tool walks through all the defconfig files to move the config
+options specified by the recipe file.
+
+The log is also displayed on the terminal.
+
+Each line is printed in the format
+<defconfig_name> : <action>
+
+<defconfig_name> is the name of the defconfig
+(without the suffix _defconfig).
+
+<action> shows what the tool did for that defconfig.
+It looks like one of the followings:
+
+ - Move 'CONFIG_... '
+ This config option was moved to the defconfig
+
+ - Default value 'CONFIG_...'. Do nothing.
+ The value of this option is the same as default.
+ We do not have to add it to the defconfig.
+
+ - 'CONFIG_...' already exists in Kconfig. Do nothing.
+ This config option is already defined in Kconfig.
+ We do not need/want to touch it.
+
+ - Undefined. Do nothing.
+ This config option was not found in the config header.
+ Nothing to do.
+
+ - Failed to process. Skip.
+ An error occurred during processing this defconfig. Skipped.
+ (If -e option is passed, the tool exits immediately on error.)
+
+Finally, you will be asked, Clean up headers? [y/n]:
+
+If you say 'y' here, the unnecessary config defines are removed
+from the config headers (include/configs/*.h).
+It just uses the regex method, so you should not rely on it.
+Just in case, please do 'git diff' to see what happened.
+
+
+How does it works?
+------------------
+
+This tool runs configuration and builds include/autoconf.mk for every
+defconfig. The config options defined in Kconfig appear in the .config
+file (unless they are hidden because of unmet dependency.)
+On the other hand, the config options defined by board headers are seen
+in include/autoconf.mk. The tool looks for the specified options in both
+of them to decide the appropriate action for the options. If the option
+is found in the .config or the value is the same as the specified default,
+the option does not need to be touched. If the option is found in
+include/autoconf.mk, but not in the .config, and the value is different
+from the default, the tools adds the option to the defconfig.
+
+For faster processing, this tool handles multi-threading. It creates
+separate build directories where the out-of-tree build is run. The
+temporary build directories are automatically created and deleted as
+needed. The number of threads are chosen based on the number of the CPU
+cores of your system although you can change it via -j (--jobs) option.
+
+
+Toolchains
+----------
+
+Appropriate toolchain are necessary to generate include/autoconf.mk
+for all the architectures supported by U-Boot. Most of them are available
+at the kernel.org site, some are not provided by kernel.org.
+
+The default per-arch CROSS_COMPILE used by this tool is specified by
+the list below, CROSS_COMPILE. You may wish to update the list to
+use your own. Instead of modifying the list directly, you can give
+them via environments.
+
+
+Available options
+-----------------
+
+ -c, --color
+ Surround each portion of the log with escape sequences to display it
+ in color on the terminal.
+
+ -n, --dry-run
+ Peform a trial run that does not make any changes. It is useful to
+ see what is going to happen before one actually runs it.
+
+ -e, --exit-on-error
+ Exit immediately if Make exits with a non-zero status while processing
+ a defconfig file.
+
+ -j, --jobs
+ Specify the number of threads to run simultaneously. If not specified,
+ the number of threads is the same as the number of CPU cores.
+
+To see the complete list of supported options, run
+
+ $ tools/moveconfig.py -h
