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/7514037bcdc37But 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.I really would like to be able to use them to validate Linux Kernel changes, hence looking for that missing BIOS. If we remove ppc405 from QEMU, we won't be able to do any regression tests of Linux Kernel on those processors.If you/someone managed to compile an old version of u-boot for one of these two boards, so that we would finally have something for regression testing, we can of course also keep the boards in QEMU...I can see that it would be usefor for some cases, but unless someone volunteers to track down the necessary firmware and look after it, I think we do need to deprecate it - I certainly don't have the capacity to look into this.I will look at it, please allow me a few weeks though.Well, building it was not hard but now I'd like to know what board QEMU actually emulates, there are way too many codenames and PVRs.
yes. We should try to reduce the list below. Deprecating embedded machines is one way. C. $ ./install/bin/qemu-system-ppc -cpu ?
