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 First, you must edit the Kconfig to add the menu entries for the configs
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:
27 $ tools/moveconfig.py CONFIG_CMD_USB CONFIG_SYS_TEXT_BASE
29 The tool walks through all the defconfig files and move the given CONFIGs.
31 The log is also displayed on the terminal.
33 The log is printed for each defconfig as follows:
41 <defconfig_name> is the name of the defconfig.
43 <action*> shows what the tool did for that defconfig.
44 It looks like one of the followings:
47 This config option was moved to the defconfig
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.
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.
61 - Undefined. Do nothing.
62 This config option was not found in the config header.
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.)
71 An error occurred during processing this defconfig. Skipped.
72 (If -e option is passed, the tool exits immediately on error.)
74 Finally, you will be asked, Clean up headers? [y/n]:
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.
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
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.
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.
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.
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.
120 Surround each portion of the log with escape sequences to display it
121 in color on the terminal.
124 Specify a file containing a list of defconfigs to move
127 Perform a trial run that does not make any changes. It is useful to
128 see what is going to happen before one actually runs it.
131 Exit immediately if Make exits with a non-zero status while processing
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.
140 Only cleanup the headers; skip the defconfig processing
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.
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.
155 Show any build errors as boards are built
