My kexec-tools [1] only supports loading of arm64 elf files, so
vmlinux, or a stripped version of it.  Image is a raw binary, and
is not yet supported.

Maybe something like this is what you need:

 ./kexec -d --load /boot/vmlinux.strip --append="console=ttyAMA0 earlyprintk=pl011,0x1c090000 root=/dev/vda rw --verbose" --dtb=/boot/fdt.dtb
 ./kexec -d -e

Also, my current master branch will only work reliably with PSCI
boot.  Spin-table boot has a bug and will be unstable for the next
few days.  Spin-table will re-boot, but only the primary cpu will
come up.
