It is confusing to have both "$(PHASE_)" and "$(XPL_)" be used in our Makefiles as part of the macros to determine when to do something in our Makefiles based on what phase of the build we are in. For consistency, bring this down to a single macro and use "$(PHASE_)" only. Signed-off-by: Tom Rini <trini@konsulko.com>

|
|
|
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
|

imply_flags (int): Flags which control which implying configs are allowed
|
|
(IMPLY_...)
|
|
skip_added (bool): Don't show options which already have an imply added.
|
|
check_kconfig (bool): Check if implied symbols already have an 'imply' or
|
|
'select' for the target config, and show this information if so.
|
|
find_superset (bool): 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.
