Hi,
as tested with Sascha
you can run it from qemu (more easy to debug)
first you will need an EFI binary
you can use this one
http://ufpr.dl.sourceforge.net/project/edk2/OVMF/OVMF-X64-r15214.zip
and then you need to create a vfat FS
dd if=/dev/zero bs=1M count=10 > dosfs; mkfs.vfat dosfs
in the dosfs mounted copy the barebox.efi in /EFI/BOOT/ as BOOTx64.efi
and finally the magic
qemu-system-x86_64 -pflash OVMF.fd -nographic dosfs
Best Regards,
J.
