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 following:
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. The option is not
51 defined in the config header, either. So, this case can be just skipped.
53 - CONFIG_... is not defined in Kconfig (suspicious). Do nothing.
54 This option is defined in the config header, but its entry was not found
56 There are two common cases:
57 - You forgot to create an entry for the CONFIG before running
58 this tool, or made a typo in a CONFIG passed to this tool.
59 - The entry was hidden due to unmet 'depends on'.
60 The tool does not know if the result is reasonable, so please check it
63 - 'CONFIG_...' is the same as the define in Kconfig. Do nothing.
64 The define in the config header matched the one in Kconfig.
65 We do not need to touch it.
67 - Compiler is missing. Do nothing.
68 The compiler specified for this architecture was not found
69 in your PATH environment.
70 (If -e option is passed, the tool exits immediately.)
73 An error occurred during processing this defconfig. Skipped.
74 (If -e option is passed, the tool exits immediately on error.)
76 Finally, you will be asked, Clean up headers? [y/n]:
78 If you say 'y' here, the unnecessary config defines are removed
79 from the config headers (include/configs/*.h).
80 It just uses the regex method, so you should not rely on it.
81 Just in case, please do 'git diff' to see what happened.
87 This tool runs configuration and builds include/autoconf.mk for every
88 defconfig. The config options defined in Kconfig appear in the .config
89 file (unless they are hidden because of unmet dependency.)
90 On the other hand, the config options defined by board headers are seen
91 in include/autoconf.mk. The tool looks for the specified options in both
92 of them to decide the appropriate action for the options. If the given
93 config option is found in the .config, but its value does not match the
94 one from the board header, the config option in the .config is replaced
95 with the define in the board header. Then, the .config is synced by
96 "make savedefconfig" and the defconfig is updated with it.
98 For faster processing, this tool handles multi-threading. It creates
99 separate build directories where the out-of-tree build is run. The
100 temporary build directories are automatically created and deleted as
101 needed. The number of threads are chosen based on the number of the CPU
102 cores of your system although you can change it via -j (--jobs) option.
108 Appropriate toolchain are necessary to generate include/autoconf.mk
109 for all the architectures supported by U-Boot. Most of them are available
110 at the kernel.org site, some are not provided by kernel.org.
112 The default per-arch CROSS_COMPILE used by this tool is specified by
113 the list below, CROSS_COMPILE. You may wish to update the list to
114 use your own. Instead of modifying the list directly, you can give
115 them via environments.
122 Surround each portion of the log with escape sequences to display it
123 in color on the terminal.
126 Create a git commit with the changes when the operation is complete. A
127 standard commit message is used which may need to be edited.
130 Specify a file containing a list of defconfigs to move. The defconfig
131 files can be given with shell-style wildcards.
134 Perform a trial run that does not make any changes. It is useful to
135 see what is going to happen before one actually runs it.
138 Exit immediately if Make exits with a non-zero status while processing
142 Do "make savedefconfig" forcibly for all the defconfig files.
143 If not specified, "make savedefconfig" only occurs for cases
144 where at least one CONFIG was moved.
147 Look for moved config options in spl/include/autoconf.mk instead of
148 include/autoconf.mk. This is useful for moving options for SPL build
149 because SPL related options (mostly prefixed with CONFIG_SPL_) are
150 sometimes blocked by CONFIG_SPL_BUILD ifdef conditionals.
153 Only cleanup the headers; skip the defconfig processing
156 Specify the number of threads to run simultaneously. If not specified,
157 the number of threads is the same as the number of CPU cores.
160 Specify the git ref to clone for building the autoconf.mk. If unspecified
161 use the CWD. This is useful for when changes to the Kconfig affect the
162 default values and you want to capture the state of the defconfig from
163 before that change was in effect. If in doubt, specify a ref pre-Kconfig
164 changes (use HEAD if Kconfig changes are not committed). Worst case it will
165 take a bit longer to run, but will always do the right thing.
168 Show any build errors as boards are built
171 Instead of prompting, automatically go ahead with all operations. This
172 includes cleaning up headers and CONFIG_SYS_EXTRA_OPTIONS.
