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')
