+This is the buildroot board support for the Xilinx ZC706. The ZC706 is
+a development board based on the Xilinx Zynq-7000 based All-Programmable
+System-On-Chip.
+
+ZC706 information including schematics, reference designs, and manuals are
+available from
+http://www.xilinx.com/products/boards-and-kits/ek-z7-zc706-g.html.
+
+The U-Boot firmware for the Xilinx Zynq All Programmable SoC depends
+on some propietary code. This dependency consists of a pair of
+files are available from the Xilinx SDK installation.
+
+You will need these files from Xilinx SDK installation to generate
+the U-Boot firmware:
+	ps7_init.c
+	ps7_init.h
+
+Buildroot will create the following files and place them in the
+<output>/images directory.
+	zynq-zc706.dtb
+	rootfs.cpio.uboot
+	uImage
+	u-boot.img
+	boot.bin
+
+
+uboot.bin  -- U-Boot SPL w/ Xilinx boot.bin wrapper
+---------------------------------------------------
+
+Due to licensing issues, the files ps7_init.c/h are not able to be
+distributed with the U-Boot source code.  These files are required to make a
+boot.bin file.
+
+If you already have the Xilinx tools installed, the following sequence will
+unpack, patch and build the rfs, kernel, uboot, and uboot-spl.
+
+make zc706_defconfig
+make uboot-patch
+cp ${XILINX_SDK}/hwplatform_templates/ZC706_hw_platform/ps7_init.{c,h} \
+output/build/uboot-xilinx-v2014.1/board/xilinx/zynq/
+
+Where ${XILINX_SDK_LIB} is ${XILINX}/SDK/${VERSION}/data/embeddedsw/lib.
+
+After copying these files into the U-Boot source tree, you can
+continue the build with:
+
+make
+
+*Notice*
+While the build will successfully complete without the ps7_init.*
+files,  the uboot.bin file generated by this configuration will not
+function properly on the ZC706.  Therefore, it is imperative that
+the ps7_init.* files be copied into the U-Boot source tree any time
+the clean, or uboot-dirclean targets are made.
+
+
+Resulting system
+----------------
+A FAT32 partition should be created at the beggining of the SD Card
+and the following files should be installed:
+	/boot.bin
+	/devicetree.dtb
+	/uImage
+	/uramdisk.image.gz
+	/u-boot.img
+
+
+All needed files can be taken from output/images/
+
+boot.bin, uImage and u-boot.img are direct copies of the same files
+available on output/images/
+
+devicetree.dtb is just zynq-zc706.dtb renamed.
+
+uramdisk.image.gz is rootfs.cpio.uboot renamed
