You'll have to use a version from https://github.com/groeck/qemu. I'd recommend to use the v5.0.0-local branch. I had to make some changes to qemu to be able to boot mps2-an385. I tried to submit those changes into upstream qemu, but that was rejected because, as I was told, the qemu implementation would no longer reflect the real hardware with those changes in place.
