The EDK2 platform is ArmVirtPkg/ArmVirtXen.dsc. Unfortunately, I don't 
have the instructions at hand.
To build the EFI firmware, you should be able to use instructions in [1] 
and then use "Xen" rather than QEMU. The blob provided could be used by 
replacing adding as the kernel in the xl configuration file.
Note that I haven't used EDK2 recently. So I can't guarantee this work. 
Although, I should be able to help if there are any issues.
Cheers,
