Eventually we might want to build our own grub on ARM in order to pick
up Fu Wei's multiboot for arm64 patches, until they enter distros?

Or maybe Raisin on UEFI should be calling efibootmgr to register Xen
directly with the BIOS, and creating a xen.cfg in /boot, i.e. the way it
currently works even on x86.

Especially if it is already to a greater or lesser extent deprecated (in
favour of eventual blktap3) even on x86.
