Refactored the
sdn/Makefile
to support buildingeden-sdn
images for multiple platforms using Docker Buildx and LinuxKit. Each target architecture now produces a distinctsdn-<arch>-bios.img
and is handled via dedicated Makefile targets (e.g.,build-vm-img-linux-arm64
).Dockerfile.vm
has been updated to use the correct image based on the target architecture at build time using the standardTARGETARCH
argument.With this patch it is now supported to specify multiple platforms, like we do in the publish workflow:
(my previous PR broke the multi-platform building/publishing: https://github.com/lf-edge/eden/actions/runs/16353910243/job/46207393649)
