Move config options from headers to defconfig files.
Since Kconfig was introduced to U-Boot, we have worked on moving
config options from headers to Kconfig (defconfig).
This tool intends to help this tremendous work.
Usage
-----
First, you must edit the Kconfig to add the menu entries for the configs
you are moving.
And then run this tool giving CONFIG names you want to move.
For example, if you want to move CONFIG_CMD_USB and CONFIG_SYS_TEXT_BASE,
simply type as follows:
$ tools/moveconfig.py CONFIG_CMD_USB CONFIG_SYS_TEXT_BASE
The tool walks through all the defconfig files and move the given CONFIGs.
The log is also displayed on the terminal.
The log is printed for each defconfig as follows:
<defconfig_name>
<action1>
<action2>
<action3>
...
<defconfig_name> is the name of the defconfig.
<action*> shows what the tool did for that defconfig.
It looks like one of the following:
- Move 'CONFIG_... '
This config option was moved to the defconfig
tools: moveconfig: do not rely on type and default value given by users Commit 96464badc794 ("moveconfig: Always run savedefconfig on the moved config") changed the work flow of this tool a lot from the original intention when this tool was designed first. Since then, before running this tool, users must edit the Kconfig to add the menu entries for the configs they are moving. It means users had already specified the type and the default value for each CONFIG via its Kconfig entry. Nevertheless, users are still required to dictate the same type and the default value in the input file. This is tedious to use. So, my idea here is to deprecate the latter. Before moving forward with it, there is one issue worth mentioning; since the savedefconfig re-sync was introduced, this tool has not been able to move bool options with "default y". Joe sent a patch to solve this problem about a year ago, but it was not applied for some reasons. Now, he came back with an updated patch, so this problem will be fixed soon. For other use cases, I see no reason to require redundant dictation in the input file. Instead, the tool can know the types and default values by parsing the .config file. This commit changes the tool to use the CONFIG names, but ignore the types and default values given by the input file. This commit also fixes one bug. Prior to this commit, it could not move an integer-typed CONFIG with value 1. For example, assume we are moving CONFIG_CONS_INDEX. Please note this is an integer type option. Many board headers define this CONFIG as 1. #define CONFIG_CONS_INDEX 1 It will be converted to CONFIG_CONS_INDEX=y and moved to include/autoconf.mk, by the tools/scripts/define2mk.sed. It will cause "make savedefconfig" to fail due to the type conflict. This commit takes care of it by detecting the type and converting the CONFIG value correctly.

- CONFIG_... is not defined in Kconfig. Do nothing.
The entry for this CONFIG was not found in Kconfig. The option is not
defined in the config header, either. So, this case can be just skipped.
- CONFIG_... is not defined in Kconfig (suspicious). Do nothing.
This option is defined in the config header, but its entry was not found
in Kconfig.

There are two common cases:
- You forgot to create an entry for the CONFIG before running
this tool, or made a typo in a CONFIG passed to this tool.
- The entry was hidden due to unmet 'depends on'.
The tool does not know if the result is reasonable, so please check it
manually.

- 'CONFIG_...' is the same as the define in Kconfig. Do nothing.
The define in the config header matched the one in Kconfig.
We do not need to touch it.
- Compiler is missing. Do nothing.
The compiler specified for this architecture was not found
in your PATH environment.
(If -e option is passed, the tool exits immediately.)
- Failed to process.
An error occurred during processing this defconfig. Skipped.
(If -e option is passed, the tool exits immediately on error.)
Finally, you will be asked, Clean up headers? [y/n]:
If you say 'y' here, the unnecessary config defines are removed
from the config headers (include/configs/*.h).
It just uses the regex method, so you should not rely on it.
Just in case, please do 'git diff' to see what happened.
How does it work?
-----------------
This tool runs configuration and builds include/autoconf.mk for every
defconfig. The config options defined in Kconfig appear in the .config
file (unless they are hidden because of unmet dependency.)
On the other hand, the config options defined by board headers are seen
in include/autoconf.mk. The tool looks for the specified options in both
of them to decide the appropriate action for the options. If the given
config option is found in the .config, but its value does not match the
one from the board header, the config option in the .config is replaced
with the define in the board header. Then, the .config is synced by
"make savedefconfig" and the defconfig is updated with it.
For faster processing, this tool handles multi-threading. It creates
separate build directories where the out-of-tree build is run. The
temporary build directories are automatically created and deleted as
needed. The number of threads are chosen based on the number of the CPU
cores of your system although you can change it via -j (--jobs) option.
Toolchains
----------
Appropriate toolchain are necessary to generate include/autoconf.mk
for all the architectures supported by U-Boot. Most of them are available
at the kernel.org site, some are not provided by kernel.org. This tool uses
the same tools as buildman, so see that tool for setup (e.g. --fetch-arch).
Tips and trips
--------------
To sync only X86 defconfigs:
./tools/moveconfig.py -s -d <(grep -l X86 configs/*)
or:
grep -l X86 configs/* | ./tools/moveconfig.py -s -d -
To process CONFIG_CMD_FPGAD only for a subset of configs based on path match:
ls configs/{hrcon*,iocon*,strider*} | \
./tools/moveconfig.py -Cy CONFIG_CMD_FPGAD -d -
Finding implied CONFIGs
-----------------------
Some CONFIG options can be implied by others and this can help to reduce
the size of the defconfig files. For example, CONFIG_X86 implies
CONFIG_CMD_IRQ, so we can put 'imply CMD_IRQ' under 'config X86' and
all x86 boards will have that option, avoiding adding CONFIG_CMD_IRQ to
each of the x86 defconfig files.
This tool can help find such configs. To use it, first build a database:
./tools/moveconfig.py -b
Then try to query it:
./tools/moveconfig.py -i CONFIG_CMD_IRQ
CONFIG_CMD_IRQ found in 311/2384 defconfigs
44 : CONFIG_SYS_FSL_ERRATUM_IFC_A002769
41 : CONFIG_SYS_FSL_ERRATUM_A007075
31 : CONFIG_SYS_FSL_DDR_VER_44
28 : CONFIG_ARCH_P1010
28 : CONFIG_SYS_FSL_ERRATUM_P1010_A003549
28 : CONFIG_SYS_FSL_ERRATUM_SEC_A003571
28 : CONFIG_SYS_FSL_ERRATUM_IFC_A003399
25 : CONFIG_SYS_FSL_ERRATUM_A008044
22 : CONFIG_ARCH_P1020
21 : CONFIG_SYS_FSL_DDR_VER_46
20 : CONFIG_MAX_PIRQ_LINKS
20 : CONFIG_HPET_ADDRESS
20 : CONFIG_X86
20 : CONFIG_PCIE_ECAM_SIZE
20 : CONFIG_IRQ_SLOT_COUNT
20 : CONFIG_I8259_PIC
20 : CONFIG_CPU_ADDR_BITS
20 : CONFIG_RAMBASE
20 : CONFIG_SYS_FSL_ERRATUM_A005871
20 : CONFIG_PCIE_ECAM_BASE
20 : CONFIG_X86_TSC_TIMER
20 : CONFIG_I8254_TIMER
20 : CONFIG_CMD_GETTIME
19 : CONFIG_SYS_FSL_ERRATUM_A005812
18 : CONFIG_X86_RUN_32BIT
17 : CONFIG_CMD_CHIP_CONFIG
...
This shows a list of config options which might imply CONFIG_CMD_EEPROM along
with how many defconfigs they cover. From this you can see that CONFIG_X86
implies CONFIG_CMD_EEPROM. Therefore, instead of adding CONFIG_CMD_EEPROM to
the defconfig of every x86 board, you could add a single imply line to the
Kconfig file:
config X86
bool "x86 architecture"
...
imply CMD_EEPROM
That will cover 20 defconfigs. Many of the options listed are not suitable as
they are not related. E.g. it would be odd for CONFIG_CMD_GETTIME to imply
CMD_EEPROM.
Using this search you can reduce the size of moveconfig patches.
You can automatically add 'imply' statements in the Kconfig with the -a
option:
./tools/moveconfig.py -s -i CONFIG_SCSI \
-a CONFIG_ARCH_LS1021A,CONFIG_ARCH_LS1043A
This will add 'imply SCSI' to the two CONFIG options mentioned, assuming that
the database indicates that they do actually imply CONFIG_SCSI and do not
already have an 'imply SCSI'.
The output shows where the imply is added:
18 : CONFIG_ARCH_LS1021A arch/arm/cpu/armv7/ls102xa/Kconfig:1
13 : CONFIG_ARCH_LS1043A arch/arm/cpu/armv8/fsl-layerscape/Kconfig:11
12 : CONFIG_ARCH_LS1046A arch/arm/cpu/armv8/fsl-layerscape/Kconfig:31
The first number is the number of boards which can avoid having a special
CONFIG_SCSI option in their defconfig file if this 'imply' is added.
The location at the right is the Kconfig file and line number where the config
appears. For example, adding 'imply CONFIG_SCSI' to the 'config ARCH_LS1021A'
in arch/arm/cpu/armv7/ls102xa/Kconfig at line 1 will help 18 boards to reduce
the size of their defconfig files.
If you want to add an 'imply' to every imply config in the list, you can use
./tools/moveconfig.py -s -i CONFIG_SCSI -a all
To control which ones are displayed, use -I <list> where list is a list of
options (use '-I help' to see possible options and their meaning).
To skip showing you options that already have an 'imply' attached, use -A.
When you have finished adding 'imply' options you can regenerate the
defconfig files for affected boards with something like:
git show --stat | ./tools/moveconfig.py -s -d -
This will regenerate only those defconfigs changed in the current commit.
If you start with (say) 100 defconfigs being changed in the commit, and add
a few 'imply' options as above, then regenerate, hopefully you can reduce the
number of defconfigs changed in the commit.
Available options
-----------------
-c, --color
Surround each portion of the log with escape sequences to display it
in color on the terminal.
-C, --commit
Create a git commit with the changes when the operation is complete. A
standard commit message is used which may need to be edited.
-d, --defconfigs
Specify a file containing a list of defconfigs to move. The defconfig
files can be given with shell-style wildcards. Use '-' to read from stdin.
-n, --dry-run
Perform a trial run that does not make any changes. It is useful to
see what is going to happen before one actually runs it.
-e, --exit-on-error
Exit immediately if Make exits with a non-zero status while processing
a defconfig file.
-s, --force-sync
Do "make savedefconfig" forcibly for all the defconfig files.
If not specified, "make savedefconfig" only occurs for cases
where at least one CONFIG was moved.
-S, --spl
Look for moved config options in spl/include/autoconf.mk instead of
include/autoconf.mk. This is useful for moving options for SPL build
because SPL related options (mostly prefixed with CONFIG_SPL_) are
sometimes blocked by CONFIG_SPL_BUILD ifdef conditionals.
-H, --headers-only
Only cleanup the headers; skip the defconfig processing
-j, --jobs
Specify the number of threads to run simultaneously. If not specified,
the number of threads is the same as the number of CPU cores.
-r, --git-ref
Specify the git ref to clone for building the autoconf.mk. If unspecified
use the CWD. This is useful for when changes to the Kconfig affect the
default values and you want to capture the state of the defconfig from
before that change was in effect. If in doubt, specify a ref pre-Kconfig
changes (use HEAD if Kconfig changes are not committed). Worst case it will
take a bit longer to run, but will always do the right thing.
-v, --verbose
Show any build errors as boards are built
-y, --yes
Instead of prompting, automatically go ahead with all operations. This
includes cleaning up headers, CONFIG_SYS_EXTRA_OPTIONS, the config whitelist
and the README.

Some CONFIG options can be implied by others and this can help to reduce
the size of the defconfig files. For example, CONFIG_X86 implies
CONFIG_CMD_IRQ, so we can put 'imply CMD_IRQ' under 'config X86' and
all x86 boards will have that option, avoiding adding CONFIG_CMD_IRQ to
each of the x86 defconfig files.
This function uses the moveconfig database to find such options. It
displays a list of things that could possibly imply those in the list.
The algorithm ignores any that start with CONFIG_TARGET since these
typically refer to only a few defconfigs (often one). It also does not
display a config with less than 5 defconfigs.
The algorithm works using sets. For each target config in config_list:
- Get the set 'defconfigs' which use that target config
- For each config (from a list of all configs):
- Get the set 'imply_defconfig' of defconfigs which use that config
-
- If imply_defconfigs contains anything not in defconfigs then
this config does not imply the target config
Params:
config_list: List of CONFIG options to check (each a string)
add_imply: Automatically add an 'imply' for each config.
imply_flags: Flags which control which implying configs are allowed
(IMPLY_...)
skip_added: Don't show options which already have an imply added.
check_kconfig: Check if implied symbols already have an 'imply' or
'select' for the target config, and show this information if so.
find_superset: True to look for configs which are a superset of those
already found. So for example if CONFIG_EXYNOS5 implies an option,
but CONFIG_EXYNOS covers a larger set of defconfigs and also
implies that option, this will drop the former in favour of the
latter. In practice this option has not proved very used.
Note the terminoloy:
config - a CONFIG_XXX options (a string, e.g. 'CONFIG_CMD_EEPROM')
defconfig - a defconfig file (a string, e.g. 'configs/snow_defconfig')
