Fri Jan 3 05:11:07 EST 2014


From: Jagannadha Sutradharudu Teki <jagannadha.sutradharudu-teki at xilinx.com>

This patch provides a basic fdt support for zynq u-boot.

zynq-generic.dts-> DTS for zc702

u-boot build: once configuring of a board done
for building dtb with zynq-zed.dts as an input
zynq-uboot> make DEVICE_TREE=zynq-zed
