env: migrate static flags list to Kconfig

2026-05-25T19:44:40Z

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.

siemens: capricorn: protect environment

2026-02-28T18:31:50Z

With ENV_WRITEABLE_LIST only specific environment variables lisetd in CFG_ENV_FLAGS_LIST_STATIC are read from the u-boot environment storage. All other environment variables are set to default values and are not written back to the storage. The u-boot environment usually stays for the lifetime of the product. There is no A/B copy mechanism as for the firmware itself. That means that incompatible changes to environment variables in future u-boot versions may lead to serious issues if the old environment is used with a new u-boot version or vice versa. Having this protection in place ensures that only a limited set of environment variables are persisted across u-boot versions. All the macros not listed in CFG_ENV_FLAGS_LIST_STATIC are now part of the u-boot binary which is redundant and immutable. This guarantees that the u-boot version and the default values of these environment variables are always in sync and cannot be changed at runtime. ustate and rastate are not relevant for u-boot itself. ustate is used by swupdate which persists the transaction state in the environment. rastate is a similar variable used by another user space application.
