9 Move config options from headers to defconfig files.
11 Since Kconfig was introduced to U-Boot, we have worked on moving
12 config options from headers to Kconfig (defconfig).
14 This tool intends to help this tremendous work.
20 This tool takes one input file. (let's say 'recipe' file here.)
21 The recipe describes the list of config options you want to move.
22 Each line takes the form:
23 <config_name> <type> <default>
24 (the fields must be separated with whitespaces.)
26 <config_name> is the name of config option.
28 <type> is the type of the option. It must be one of bool, tristate,
31 <default> is the default value of the option. It must be appropriate
32 value corresponding to the option type. It must be either y or n for
33 the bool type. Tristate options can also take m (although U-Boot has
34 not supported the module feature).
36 You can add two or more lines in the recipe file, so you can move
37 multiple options at once.
39 Let's say, for example, you want to move CONFIG_CMD_USB and
42 The type should be bool, hex, respectively. So, the recipe file
43 should look like this:
47 CONFIG_SYS_TEXT_BASE hex 0x00000000
49 Next you must edit the Kconfig to add the menu entries for the configs
52 And then run this tool giving the file name of the recipe
54 $ tools/moveconfig.py recipe
56 The tool walks through all the defconfig files to move the config
57 options specified by the recipe file.
59 The log is also displayed on the terminal.
61 Each line is printed in the format
62 <defconfig_name> : <action>
64 <defconfig_name> is the name of the defconfig
65 (without the suffix _defconfig).
67 <action> shows what the tool did for that defconfig.
68 It looks like one of the followings:
71 This config option was moved to the defconfig
73 - Default value 'CONFIG_...'. Do nothing.
74 The value of this option is the same as default.
75 We do not have to add it to the defconfig.
77 - 'CONFIG_...' already exists in Kconfig. Do nothing.
78 This config option is already defined in Kconfig.
79 We do not need/want to touch it.
81 - Undefined. Do nothing.
82 This config option was not found in the config header.
85 - Compiler is missing. Do nothing.
86 The compiler specified for this architecture was not found
87 in your PATH environment.
88 (If -e option is passed, the tool exits immediately.)
91 An error occurred during processing this defconfig. Skipped.
92 (If -e option is passed, the tool exits immediately on error.)
94 Finally, you will be asked, Clean up headers? [y/n]:
96 If you say 'y' here, the unnecessary config defines are removed
97 from the config headers (include/configs/*.h).
98 It just uses the regex method, so you should not rely on it.
99 Just in case, please do 'git diff' to see what happened.
105 This tool runs configuration and builds include/autoconf.mk for every
106 defconfig. The config options defined in Kconfig appear in the .config
107 file (unless they are hidden because of unmet dependency.)
108 On the other hand, the config options defined by board headers are seen
109 in include/autoconf.mk. The tool looks for the specified options in both
110 of them to decide the appropriate action for the options. If the option
111 is found in the .config or the value is the same as the specified default,
112 the option does not need to be touched. If the option is found in
113 include/autoconf.mk, but not in the .config, and the value is different
114 from the default, the tools adds the option to the defconfig.
116 For faster processing, this tool handles multi-threading. It creates
117 separate build directories where the out-of-tree build is run. The
118 temporary build directories are automatically created and deleted as
119 needed. The number of threads are chosen based on the number of the CPU
120 cores of your system although you can change it via -j (--jobs) option.
126 Appropriate toolchain are necessary to generate include/autoconf.mk
127 for all the architectures supported by U-Boot. Most of them are available
128 at the kernel.org site, some are not provided by kernel.org.
130 The default per-arch CROSS_COMPILE used by this tool is specified by
131 the list below, CROSS_COMPILE. You may wish to update the list to
132 use your own. Instead of modifying the list directly, you can give
133 them via environments.
140 Surround each portion of the log with escape sequences to display it
141 in color on the terminal.
144 Specify a file containing a list of defconfigs to move
147 Peform a trial run that does not make any changes. It is useful to
148 see what is going to happen before one actually runs it.
151 Exit immediately if Make exits with a non-zero status while processing
155 Only cleanup the headers; skip the defconfig processing
158 Specify the number of threads to run simultaneously. If not specified,
159 the number of threads is the same as the number of CPU cores.
162 Show any build errors as boards are built
