Hello all, is there any kconfig mechanism in u-boot to append environment variable to the default one?
Well, despite the name, CONFIG_EXTRA_ENV_SETTINGS is not settable via kconfig, but only from board header file. And while it works, it's rather cumbersome to maintain that macro expanding to a string with all the embedded \0 and the required \ continuations etc.
I just want to chime in here to note that the biggest blocker to removing CONFIG_EXTRA_ENV_SETTINGS and migrating it to board.env files is how to handle, exactly, distroboot support. Aside from that,
I will get back to that before long.
whatever is done in CONFIG_EXTRA_ENV_SETTINGS can be done in the .env file (unless there's some other fancy macro work being done that I've missed).
