+This is the buildroot board support for the Avnet Zedboard. The Zedboard is
+a development board based on the Xilinx Zynq-7000 based All-Programmable
+System-On-Chip.
+
+Zedboard information including schematics, reference designs, and manuals are
+available from http://www.zedboard.org .
+
+To boot the Zedboard using a buildroot generated image copy the following files
+to the sdcard:
+       zynq-zed.dtb -> devicetree.dtb
+       rootfs.cpio.gz.uboot -> uramdisk.image.gz
+       uImage -> uImage
