The arm64 Xen binary is both a valid PE (UEFI) application _and_ a
normal kernel image which can be booted frmo uboot using
bootm/bootz/booti etc.

(The same is true of e.g. Linux kernel images on arm64 BTW, it just so
happens that the signatures and magic metadata for both formats do not
interfere with each other, which is very convenient!)

Booting Xen from u-boot is described in the wiki, I suggest you start
with:
