Please keep this option for the stemmy board. It's still used occasionally to boot the original downstream/vendor kernel which is currently still necessary to charge the battery on these devices. See commit e2f82f93 ("board: stemmy: Copy atags for booting downstream/vendor kernel") [1] for details. Thanks!
