John Crispin 2d45ad07fc zynq: add new target
Add support for Xilinx ZC702 Dev board

Zynq target is using 4.4 kernel and mainline 2016.1 u-boot.

Patch is tested with Xilinx ZC702 Dev board with SD boot mode.

known issues:
 - no QSPI driver in 4.4 kernel: no QSPI flash support
 - USB is not working in 4.4 kernel

# U-Boot firmware supports the booting of images in the Flattened Image
# Tree (FIT) format. The FIT format uses a device tree structure to
# describe a kernel image, device tree blob, ramdisk, etc. This script
# creates an Image Tree Source (.its file) which can be passed to the
# 'mkimage' utility to generate an Image Tree Blob (.itb file). The .itb
# file can then be booted by U-Boot (or other bootloaders which support
# FIT images). See doc/uImage.FIT/howto.txt in U-Boot source code for
# additional information on FIT images.
