True. I did some more research, and seems like there was once support for those boards in u-boot, but it got removed there a couple of years ago already: https://gitlab.com/qemu-project/u-boot/-/commit/98f705c9cefdf https://gitlab.com/qemu-project/u-boot/-/commit/b147ff2f37d5b https://gitlab.com/qemu-project/u-boot/-/commit/7514037bcdc37 > But I agree that there seem to be no signs of anybody actually > successfully using these boards for anything, so we should > deprecate-and-delete them. Yes, let's mark them as deprecated now ... if someone still uses them and speaks up, we can still revert the deprecation again. Thomas
