Xilinx uses a prebootloader and a bootloader for the Zynq, barebox does not. So you would have to put all values into the respective two files. And you need to run scripts/zynq_mkimage for the checksum (but I think the Makefile already does that). I wish I could be of more help here, but I can't really remember the actual steps necessary and I don't have a ps7_init handy at the moment.
