dts: zynq: Add basic fdt support
This patch provides a basic fdt support for zynq u-boot. zynq-7000.dtsi-> initial arch dts file zynq-zed.dts -> initial zed board dts file more devices should be added in subsequent patches. 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 Enabled CONFIG_OF_SEPARATE for building dtb separately. There is a new binary called u-boot-dtb.bin which is a u-boot with devicetree supported. Signed-off-by: Jagannadha Sutradharudu Teki <jaganna@xilinx.com>
