| 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 |
| |
| Next you must edit the Kconfig to add the menu entries for the configs |
| you are moving. |
| |
| 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. |
| |
| -d, --defconfigs |
| Specify a file containing a list of defconfigs to move |
| |
| -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. |
| |
| -H, --headers-only |
| Only cleanup the headers; skip the defconfig processing |
| |
| -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. |
| |
| -v, --verbose |
| Show any build errors as boards are built |
| |
| To see the complete list of supported options, run |
| |
| $ tools/moveconfig.py -h |
