| 9 | Move config options from headers to defconfig files. |
| 10 | |
| 11 | Since Kconfig was introduced to U-Boot, we have worked on moving |
| 12 | config options from headers to Kconfig (defconfig). |
| 13 | |
| 14 | This tool intends to help this tremendous work. |
| 15 | |
| 16 | |
| 17 | Usage |
| 18 | ----- |
| 19 | |
Masahiro Yamada | b6ef393 | 2016-05-19 15:51:58 +0900 | [diff] [blame] | 20 | First, you must edit the Kconfig to add the menu entries for the configs |
Joe Hershberger | 96464ba | 2015-05-19 13:21:17 -0500 | [diff] [blame] | 21 | you are moving. |
| 22 | |
Masahiro Yamada | b6ef393 | 2016-05-19 15:51:58 +0900 | [diff] [blame] | 23 | And then run this tool giving CONFIG names you want to move. |
| 24 | For example, if you want to move CONFIG_CMD_USB and CONFIG_SYS_TEXT_BASE, |
| 25 | simply type as follows: |
Masahiro Yamada | 5a27c73 | 2015-05-20 11:36:07 +0900 | [diff] [blame] | 26 | |
Masahiro Yamada | b6ef393 | 2016-05-19 15:51:58 +0900 | [diff] [blame] | 27 | $ tools/moveconfig.py CONFIG_CMD_USB CONFIG_SYS_TEXT_BASE |
Masahiro Yamada | 5a27c73 | 2015-05-20 11:36:07 +0900 | [diff] [blame] | 28 | |
Masahiro Yamada | b6ef393 | 2016-05-19 15:51:58 +0900 | [diff] [blame] | 29 | The tool walks through all the defconfig files and move the given CONFIGs. |
Masahiro Yamada | 5a27c73 | 2015-05-20 11:36:07 +0900 | [diff] [blame] | 30 | |
| 31 | The log is also displayed on the terminal. |
| 32 | |
Masahiro Yamada | 1d08556 | 2016-05-19 15:52:02 +0900 | [diff] [blame] | 33 | The log is printed for each defconfig as follows: |
Masahiro Yamada | 5a27c73 | 2015-05-20 11:36:07 +0900 | [diff] [blame] | 34 | |
Masahiro Yamada | 1d08556 | 2016-05-19 15:52:02 +0900 | [diff] [blame] | 35 | <defconfig_name> |
| 36 | <action1> |
| 37 | <action2> |
| 38 | <action3> |
| 39 | ... |
Masahiro Yamada | 5a27c73 | 2015-05-20 11:36:07 +0900 | [diff] [blame] | 40 | |
Masahiro Yamada | 1d08556 | 2016-05-19 15:52:02 +0900 | [diff] [blame] | 41 | <defconfig_name> is the name of the defconfig. |
| 42 | |
| 43 | <action*> shows what the tool did for that defconfig. |
Masahiro Yamada | 5a27c73 | 2015-05-20 11:36:07 +0900 | [diff] [blame] | 44 | It looks like one of the followings: |
| 45 | |
| 46 | - Move 'CONFIG_... ' |
| 47 | This config option was moved to the defconfig |
| 48 | |
Masahiro Yamada | cc00829 | 2016-05-19 15:51:56 +0900 | [diff] [blame] | 49 | - CONFIG_... is not defined in Kconfig. Do nothing. |
| 50 | The entry for this CONFIG was not found in Kconfig. |
| 51 | There are two common cases: |
| 52 | - You forgot to create an entry for the CONFIG before running |
| 53 | this tool, or made a typo in a CONFIG passed to this tool. |
| 54 | - The entry was hidden due to unmet 'depends on'. |
| 55 | This is correct behavior. |
Masahiro Yamada | 5a27c73 | 2015-05-20 11:36:07 +0900 | [diff] [blame] | 56 | |
Masahiro Yamada | cc00829 | 2016-05-19 15:51:56 +0900 | [diff] [blame] | 57 | - 'CONFIG_...' is the same as the define in Kconfig. Do nothing. |
| 58 | The define in the config header matched the one in Kconfig. |
| 59 | We do not need to touch it. |
Masahiro Yamada | 5a27c73 | 2015-05-20 11:36:07 +0900 | [diff] [blame] | 60 | |
| 61 | - Undefined. Do nothing. |
| 62 | This config option was not found in the config header. |
| 63 | Nothing to do. |
| 64 | |
Masahiro Yamada | 90ed6cb | 2016-05-19 15:51:53 +0900 | [diff] [blame] | 65 | - Compiler is missing. Do nothing. |
| 66 | The compiler specified for this architecture was not found |
| 67 | in your PATH environment. |
| 68 | (If -e option is passed, the tool exits immediately.) |
| 69 | |
| 70 | - Failed to process. |
Masahiro Yamada | 5a27c73 | 2015-05-20 11:36:07 +0900 | [diff] [blame] | 71 | An error occurred during processing this defconfig. Skipped. |
| 72 | (If -e option is passed, the tool exits immediately on error.) |
| 73 | |
| 74 | Finally, you will be asked, Clean up headers? [y/n]: |
| 75 | |
| 76 | If you say 'y' here, the unnecessary config defines are removed |
| 77 | from the config headers (include/configs/*.h). |
| 78 | It just uses the regex method, so you should not rely on it. |
| 79 | Just in case, please do 'git diff' to see what happened. |
| 80 | |
| 81 | |
Masahiro Yamada | b6ef393 | 2016-05-19 15:51:58 +0900 | [diff] [blame] | 82 | How does it work? |
| 83 | ----------------- |
Masahiro Yamada | 5a27c73 | 2015-05-20 11:36:07 +0900 | [diff] [blame] | 84 | |
| 85 | This tool runs configuration and builds include/autoconf.mk for every |
| 86 | defconfig. The config options defined in Kconfig appear in the .config |
| 87 | file (unless they are hidden because of unmet dependency.) |
| 88 | On the other hand, the config options defined by board headers are seen |
| 89 | in include/autoconf.mk. The tool looks for the specified options in both |
Masahiro Yamada | b6ef393 | 2016-05-19 15:51:58 +0900 | [diff] [blame] | 90 | of them to decide the appropriate action for the options. If the given |
| 91 | config option is found in the .config, but its value does not match the |
| 92 | one from the board header, the config option in the .config is replaced |
| 93 | with the define in the board header. Then, the .config is synced by |
| 94 | "make savedefconfig" and the defconfig is updated with it. |
Masahiro Yamada | 5a27c73 | 2015-05-20 11:36:07 +0900 | [diff] [blame] | 95 | |
| 96 | For faster processing, this tool handles multi-threading. It creates |
| 97 | separate build directories where the out-of-tree build is run. The |
| 98 | temporary build directories are automatically created and deleted as |
| 99 | needed. The number of threads are chosen based on the number of the CPU |
| 100 | cores of your system although you can change it via -j (--jobs) option. |
| 101 | |
| 102 | |
| 103 | Toolchains |
| 104 | ---------- |
| 105 | |
| 106 | Appropriate toolchain are necessary to generate include/autoconf.mk |
| 107 | for all the architectures supported by U-Boot. Most of them are available |
| 108 | at the kernel.org site, some are not provided by kernel.org. |
| 109 | |
| 110 | The default per-arch CROSS_COMPILE used by this tool is specified by |
| 111 | the list below, CROSS_COMPILE. You may wish to update the list to |
| 112 | use your own. Instead of modifying the list directly, you can give |
| 113 | them via environments. |
| 114 | |
| 115 | |
| 116 | Available options |
| 117 | ----------------- |
| 118 | |
| 119 | -c, --color |
| 120 | Surround each portion of the log with escape sequences to display it |
| 121 | in color on the terminal. |
| 122 | |
Joe Hershberger | 91040e8 | 2015-05-19 13:21:19 -0500 | [diff] [blame] | 123 | -d, --defconfigs |
| 124 | Specify a file containing a list of defconfigs to move |
| 125 | |
Masahiro Yamada | 5a27c73 | 2015-05-20 11:36:07 +0900 | [diff] [blame] | 126 | -n, --dry-run |
Masahiro Yamada | b6ef393 | 2016-05-19 15:51:58 +0900 | [diff] [blame] | 127 | Perform a trial run that does not make any changes. It is useful to |
Masahiro Yamada | 5a27c73 | 2015-05-20 11:36:07 +0900 | [diff] [blame] | 128 | see what is going to happen before one actually runs it. |
| 129 | |
| 130 | -e, --exit-on-error |
| 131 | Exit immediately if Make exits with a non-zero status while processing |
| 132 | a defconfig file. |
| 133 | |
Joe Hershberger | 2144f88 | 2015-05-19 13:21:20 -0500 | [diff] [blame] | 134 | -H, --headers-only |
| 135 | Only cleanup the headers; skip the defconfig processing |
| 136 | |
Masahiro Yamada | 5a27c73 | 2015-05-20 11:36:07 +0900 | [diff] [blame] | 137 | -j, --jobs |
| 138 | Specify the number of threads to run simultaneously. If not specified, |
| 139 | the number of threads is the same as the number of CPU cores. |
| 140 | |
Joe Hershberger | 95bf9c7 | 2015-05-19 13:21:24 -0500 | [diff] [blame] | 141 | -v, --verbose |
| 142 | Show any build errors as boards are built |
| 143 | |
Masahiro Yamada | 5a27c73 | 2015-05-20 11:36:07 +0900 | [diff] [blame] | 144 | To see the complete list of supported options, run |
