|
|
|
|
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')
