 | |
| 
 | |
|     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 qconfig 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
