(And I saw 12/12 of v2, which basically replaces 14/14.) That makes things clear. Perhaps, if you're going to send a v3, you might move this change into 12/12. At least, I see little reason to add this choice block in two separate steps in this series. (Side note: you _might_ be able to drop config DTB_ATH79_NONE entirely if you also replace default DTB_ATH79_NONE with optional optional is a little used option for choice blocks. I haven't tested this, so this suggestion could end up wasting your time. And even then this all looks like a complicated way to set just DTB_TL_WR1043ND_V1. I suppose you expect to add things to this choice block in the future.)
