[PATCH v5 04/44] moveconfig: Update to detect / correct missing SPL Kconfigs

Simon Glass
2023-02-22T16:48:51Z

This adds quite a few more features, all designed to detect problems with
Kconfig options and their use. It can find options mentioned in the source
code which are not in the Kconfig and vice versa. It can convert SPL
usages of non-SPL Kconfig options (i.e. changing CONFIG_IS_ENABLED() to
IS_ENABLED() and CONFIG_$(SPL)_FOO to CONFIG_FOO, creating commits
automatically if requested.

These features are only useful for code clean-up, not for normal
development.
