Dear Simon,

Add a feature that brings in a .env file associated with the board config, if present. To use it, create a file in a board/<vendor>/env directory called <board>.env (or common.env if you want the same environment for all boards).
This should be no exclusive "or" here. If a common.env exists, it should be used for all boards, and if additionally one ore more <board>.env files exist, these should ALSO be applied to the respective boards.
Is it not enough to use #include in the main file? We have a similar feature with the u-boot.dtsi files and in that case we only choose the most specific.
1) This requires that the .env files are run through CPP, which is only added in a later patch.
2) Even if I add an "#include board/<vendor>/env/common.env" in my <board>.env files, your logic would trigger on the existence of the common.env file and ignore the <board>.env files.
Best regards,
Wolfgang Denk
