I worked on a port a few years ago but never had time to properly upstream it. I am not aware for more work since then. With my work, I was able to boot FreeBSD as both DomU and Dom0 guest. The work can be found on my git repository [1]. IIRC the branch dev-arm64 contains just enough boot a DomU and Dom0. There are other branches (e.g dev-evtchn, dev-xen-upstream) that contains cleanup series for making easier to have common Xen code between architectures. I am happy to provide help using the branches if you are interested. Although I haven't worked on them for the past 3 years :).
