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 | ||
b6ef393a | 20 | First, you must edit the Kconfig to add the menu entries for the configs |
96464bad JH |
21 | you are moving. |
22 | ||
b6ef393a MY |
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: | |
5a27c734 | 26 | |
b6ef393a | 27 | $ tools/moveconfig.py CONFIG_CMD_USB CONFIG_SYS_TEXT_BASE |
5a27c734 | 28 | |
b6ef393a | 29 | The tool walks through all the defconfig files and move the given CONFIGs. |
5a27c734 MY |
30 | |
31 | The log is also displayed on the terminal. | |
32 | ||
1d085568 | 33 | The log is printed for each defconfig as follows: |
5a27c734 | 34 | |
1d085568 MY |
35 | <defconfig_name> |
36 | <action1> | |
37 | <action2> | |
38 | <action3> | |
39 | ... | |
5a27c734 | 40 | |
1d085568 MY |
41 | <defconfig_name> is the name of the defconfig. |
42 | ||
43 | <action*> shows what the tool did for that defconfig. | |
5a27c734 MY |
44 | It looks like one of the followings: |
45 | ||
46 | - Move 'CONFIG_... ' | |
47 | This config option was moved to the defconfig | |
48 | ||
cc008299 MY |
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. | |
56 | ||
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. | |
5a27c734 MY |
60 | |
61 | - Undefined. Do nothing. | |
62 | This config option was not found in the config header. | |
63 | Nothing to do. | |
64 | ||
90ed6cba MY |
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. | |
5a27c734 MY |
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 | ||

82 | How does it work? |
83 | ----------------- | |
5a27c734 MY |
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 | |
b6ef393a MY |
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. | |
5a27c734 MY |
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 | ||
91040e85 JH |
123 | -d, --defconfigs |
124 | Specify a file containing a list of defconfigs to move | |
125 | ||
5a27c734 | 126 | -n, --dry-run |
b6ef393a | 127 | Perform a trial run that does not make any changes. It is useful to |
5a27c734 MY |
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 | ||
8513dc04 MY |
134 | -s, --force-sync |
135 | Do "make savedefconfig" forcibly for all the defconfig files. | |
136 | If not specified, "make savedefconfig" only occurs for cases | |
137 | where at least one CONFIG was moved. | |
138 | ||
2144f880 JH |
139 | -H, --headers-only |
140 | Only cleanup the headers; skip the defconfig processing | |
141 | ||
5a27c734 MY |
142 | -j, --jobs |
143 | Specify the number of threads to run simultaneously. If not specified, | |
144 | the number of threads is the same as the number of CPU cores. | |
145 | ||
6b96c1a1 JH |
146 | -r, --git-ref |
147 | Specify the git ref to clone for building the autoconf.mk. If unspecified | |
148 | use the CWD. This is useful for when changes to the Kconfig affect the | |
149 | default values and you want to capture the state of the defconfig from | |
150 | before that change was in effect. If in doubt, specify a ref pre-Kconfig | |
151 | changes (use HEAD if Kconfig changes are not committed). Worst case it will | |
152 | take a bit longer to run, but will always do the right thing. | |
153 | ||
95bf9c7e JH |
154 | -v, --verbose |
155 | Show any build errors as boards are built | |
156 | ||
5a27c734 MY |
157 | To see the complete list of supported options, run |
158 | ||
159 | $ tools/moveconfig.py -h | |
