2026-05-25env: migrate static flags list to KconfigJames Hilliard
Environment callbacks can already be configured from Kconfig with CONFIG_ENV_CALLBACK_LIST_STATIC, but static environment flags still require board headers to define CFG_ENV_FLAGS_LIST_STATIC. Add CONFIG_ENV_FLAGS_LIST_STATIC and use it as the only board-provided static environment flags list. Convert the remaining default-config users from CFG_ENV_FLAGS_LIST_STATIC to defconfig settings and drop the legacy header macro from ENV_FLAGS_LIST_STATIC. Move the environment flags format documentation out of README and into the developer environment documentation. Include the format in the Kconfig help as well. This lets boards configure writeable-list policy and type validation from defconfig without adding a config header solely for env flags. This preserves the behavior of default configs. Header-only cases that were inactive in upstream defconfigs are not converted into defconfig entries: iot2050 can add its list when enabling ENV_WRITEABLE_LIST, and smegw01 can add mmcdev:dw support if the unlocked SYS_BOOT_LOCKED=n configuration is needed.

2023-01-20global: Finish CONFIG -> CFG migrationTom Rini
At this point, the remaining places where we have a symbol that is defined as CONFIG_... are in fairly odd locations. While as much dead code has been removed as possible, some of these locations are simply less obvious at first. In other cases, this code is used, but was defined in such a way as to have been missed by earlier checks. Perform a rename of all such remaining symbols to be CFG_... rather than CONFIG_...
