How to boot riscv-poky-linux on zed board?

I've follow [issue #3](https://github.com/riscv/riscv-poky/issues/3) and successfully boot linux with `runspike riscv64`. However, I cannot execute the same boot.bin and vmlinux on zed board.

How can I boot linux on zed board with the boot.bin and vmlinux?
