When running make localmodconfig, streamline_config.pl reads loaded
modules and maps each module object to its corresponding Kconfig
symbol(s) using repository Makefiles.
In several instances, a loaded module corresponds to an object
controlled by a boolean symbol (e.g. config FOO declared as bool), or is
a composite module that depends on a boolean configuration. Because
boolean options only accept "=y" or disabled, they cannot be configured
as loadable modules ("=m").
Previously, if such a symbol was not already built-in ("=y") in the
baseline configuration, the final integrity check emitted an ambiguous
diagnostic. For example
foo did not have configs CONFIG_FOO
Further investigation is required by developers to determine whether the
module was out-of-tree, its dependencies were unmet, or it failed due to
a type constraint. Address this by:
1. Tracking symbol types in a %types hash during Kconfig parsing.
2. Enhancing the final integrity check when running localmodconfig
(!$localyesconfig) to explicitly annotate boolean symbols.
For example:
module cec did not have configs CONFIG_CEC_CORE (tristate) CONFIG_RAS_CEC (boolean, not supported with =m)
