2019-11-23moveconfig.py: Fix more Python3 UTF issuesTom Rini
With the move to using Python 3 for real, we encounter two different issues. First, the file include/video_font_data.h includes at least one UTF-16 character. Given that it does not include any CONFIG symbols it is easiest to just ignore this file. Next, we encounter similar problems with some dts/dtsi files that come from Linux. In this case it's easiest to simply ignore all dts/dtsi files as there will not be CONFIG symbols for us to migrate in them.

2019-10-08kconfiglib: Update to the 12.14.0 releaseTom Rini
A large number of changes have happened upstream since our last sync which was to 375506d. The reason to do the upgrade at this point is for improved Python 3 support. As part of this upgrade we need to update moveconfig.py and genboardscfg.py the current API. This is: - Change "kconfiglib.Config" calls to "kconfiglib.Kconfig" - Change get_symbol() calls to syms.get(). - Change get_value() to str_value.

2019-07-09moveconfig: expand simple expressionsMarkus Klotzbuecher
Add support for expanding simple expressions and sizes such as "(4 * 1024)", "(512 << 10)" or "(SZ_256K)". This can help to significantly reduce the number of "suspicious" moves, such as 'CONFIG_ENV_SIZE="(64 << 10)"' was removed by savedefconfig. If the expansion fails, it falls back to the original string.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2017-09-29kconfiglib: update with 'imply' supportUlf Magnusson
Corresponds to 375506d (File writing nit) from upstream (https://github.com/ulfalizer/Kconfiglib). Adds proper 'imply' support and fixes a few minor issues, one of which previously triggered the following weird warning: configs/taurus_defconfig: /tmp/tmpisI45S:6: warning: assignment to SPL_LDSCRIPT changes mode of containing choice from "arch/$(ARCH)/cpu/u-boot-spl.lds" to "y" The change in 8639f69 (genconfig.py: Print defconfig next to warnings) was reapplied. tools/moveconfig.py previously depended on a hack that merged 'select's with 'imply's. It was modified to look at the union of Symbol.get_selected_symbols() and Symbol.get_implied_symbols(), which should give the same behavior. tools/genboardscfg.py was verified to produce identical board.cfg's before and after the change.

2017-07-22RFC: moveconfig: Use toolchains from buildmanSimon Glass
It is annoying to have to set up and maintain two sets of toolchains, one for buildman and one for moveconfig. Adjust moveconfig to make use to buildman's toolchains. This should make things easier. One missing feature is the ability to specify the toolchain on the command line with a special environment variable, e.g. CROSS_COMPILE_ARM. I'm not sure if that is useful, but if it is it could be implemented in buildman.

2017-07-11moveconfig: Allow automatic location and adding of 'imply'Simon Glass
By using a Kconfig parser we can find the location of each option in the Kconfig tree. Using the information from the database we can then automatically add an 'imply' option into the right place if requested by the user. Add a -a option to support adding 'imply' options. Display the location of any existing 'imply' option so that progress can be examined. Add a -A option to hide any existing 'imply' options so that already-completed additions need not be considered further. Also add documentation for this feature.

2017-07-11moveconfig: Allow control of which implying configs are shownSimon Glass
Sometimes it is useful to display CONFIG_TARGET or CONFIG_CMD configs. Add an option to control this. Also we generally ignore implying configs which affect fewer than 5 boards. But sometimes it is useful to show those those, so add an option that reduces the minimum to two. ERRATUM configs are never useful for implying things, so ignore those.

2017-07-11moveconfig: Allow piping in 'git show --stat' outputSimon Glass
It is useful to be able to process only a subset of boards to save time. Often that subset is defined by the defconfig files in a git commit. This change allows things like: # Build the database ./tools.moveconfig.py -b # Find some implying configs ./tools/moveconfig.py -i CONFIG_X # Add some 'imply' statements to Kconfig files ./tools/moveconfig.py -i CONFIG_X -a CONFIG_A,CONFIG_B # Reprocess the defconfig files to see if we can drop some changes git show --stat | ./tools/moveconfig.py -s -d - # Update the commit, with fewer defconfig changes gii commit -au Where the commit contains defconfig files, this will reprocess them to take account of the imply statements that you added.

2017-07-11moveconfig: Support looking for implied CONFIG optionsSimon Glass
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. Add a -i option which searches for such options. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Heiko Schocher <hs@denx.de>
2017-07-11moveconfig: Support building a simple config databaseSimon Glass
Add a -b option which scans all the defconfigs and builds a database of all the CONFIG options used by each. This is useful for querying later. At present this only works with the separate -b option, which does not move any configs. It would be possible to adjust the script to build the database automatically when moving configs, but this might not be useful as the database does not change that often.

Prior to this commit, the tool could not move options guarded by CONFIG_SPL_BUILD ifdef conditionals because they do not show up in include/autoconf.mk.

2016-09-06tools: moveconfig: warn loudly if moved option has no entry in KconfigMasahiro Yamada
Currently, the tool gives up moving an option quietly if its entry was not found in Kconfig. If the option is not defined in the config header in the first place, it is no problem (as the Kconfig entry may have been hidden by reasonable "depends on"). However, if the option is defined in the config header, the missing Kconfig entry is a sign of possible behavior change. It is highly recommended to manually check if the option has been moved as expected. In this case, let's add "suspicious" in the log and change the log color (if --color option is given) to make it stand out. This was suggested by Tom in [1].

We mostly move config options from board header files to Kconfig, but sometimes config defines come from CONFIG_SYS_EXTRA_OPTIONS.

Now, we want to migrate to primary entries in Kconfig rather than option list in CONFIG_SYS_EXTRA_OPTIONS, so it should be helpful to have the tool to cleanup CONFIG_SYS_EXTRA_OPTIONS automatically.

2016-08-05tools: moveconfig: trim garbage lines after header cleanupsMasahiro Yamada
The tools/moveconfig.py has a feature to cleanup #define/#undef's of moved config options, but I want this tool to do a better job. For example, when we are moving CONFIG_FOO and its define is surrounded by #ifdef ... #endif, like follows: #ifdef CONFIG_BAR # define CONFIG_FOO #endif The header cleanup will leave empty #ifdef ... #endif: #ifdef CONFIG_BAR #endif Likewise, if a define line between two blank lines <blank line> #define CONFIG_FOO <blank lines. ... is deleted, the result of the clean-up will be successive empty lines, which is a coding-style violation. It is tedious to remove left-over garbage lines manually, so I want the tool to take care of this. The tool's job is still not perfect, so we should check the output of the tool, but I hope our life will be much easier with this patch. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2016-06-22tools: moveconfig: show suspicious boards with possible misconversionMasahiro Yamada
There are some cases where config options are moved, but they are ripped off at the final savedefconfig stage: - The moved option is not user-configurable, for example, due to a missing prompt in the Kconfig entry - The config was not defined in the original config header despite the Kconfig specifies it as non-bool type - The config define in the header contains reference to another macro, for example: #define CONFIG_CONS_INDEX (CONFIG_SYS_LPC32XX_UART - 2) The current moveconfig does not support recursive macro expansion. In these cases, the conversion is very likely to be an unexpected result. That is why I decided to display the log in yellow color in commit 5da4f857beac ("tools: moveconfig: report when CONFIGs are removed by savedefconfig"). It would be nice to display the list of suspicious boards when the tool finishes processing. It is highly recommended to check the defconfigs once again when this message is displayed.

This is convenient for the case where something in the Kconfig has changed such that the defconfig is no longer complete with the new Kconfigs. This feature allows the .config to be built assuming those old Kconfigs, but then savedefconfig based on the new state of the Kconfigs. If in doubt, always specify this switch. It will always do the right thing even if not required, but if it was required and you don't use it, the moved configs will be incorrect.
