commit: https://git.buildroot.net/buildroot/commit/?id=0542bb79e823505a730b6a2c2f01b33b6293cf03
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Allow multiple file names to be listed in
BR2_TARGET_UBOOT_ENVIMAGE_SOURCE, concatenating them in the order
listed.
This allows the bulk of the environment to be shared across multiple
boards using a common environment file with board-specific values
supplied in a secondary environment source file.
