I'm afraid that nobody has landed the necessary porting work for this
yet (I don't think I've even seen attempts at it, although that doesn't
mean they don't exist somewhere), and no arm-xen or arm64-xen
CPU/platform combination is defined yet, even in upstream git master.
It won't be possible to fix this bug in Debian until that work has been
done upstream.

The only Xen support that GRUB has on ARM at the moment is a loader,
allowing an instance of GRUB running on bare metal to load a Xen
hypervisor.  Support for running in a PV guest is rather different.
