The Parallella is a single board computer showcasing the Epiphany
multi-core processor from Adapteva. The board uses a Zynq-7000 SoC which
interconnects to the Epiphany. This patch adds support for booting on
the Zynq system of the board.

More information on this board is available at: https://parallella.org/
