Interesting timing... yesterday I worked on updating Ivo De Decker's work on cross-building u-boot images for multiple architectures and building an arch:all u-boot-qemu package: https://bugs.debian.org/907573 Which demonstrates that in theory it would be possible to make almost all of the u-boot packages arch:all... essentially any architecture with working cross-compilers for amd64. On the other hand, people went through a lot of trouble to make multi-arch a reality, and you can also install u-boot-sunxi packages using multi-arch. I'm not sure what all of the implications are for building more u-boot packages as arch:all ... some that come to mind: All of the u-boot-sunxi platforms for both armhf and arm64 would end up in a single package, which might be unfortunate on some resource-constrained systems... Ideally for the end-user, there would be one package per u-boot target, but I've thus far only broken it up by rough approximations of SoC families to mitigate the proliferation of many small packages and getting stuck in NEW for every new platform added. Being able to do development on a faster platform (e.g. amd64) would be nice, although in most cases u-boot is already fairly cross-buildable for any target where this would be feasible, so that seems a mixed argument. One thought would be to build a single arch:all package with all of the cross-buildable targets, and appropriate Provides and Conflicts on other u-boot-* packages, while still building natively as well... maybe a little redundant essentially having the same u-boot images in two places. Certainly too late for buster, of course, but an interesting idea to mull over for bullseye... live well, vagrant
