+Xilinx Zynq 7000
+================
+
+Barebox has support for the Xilinx Zynq 7000.
+
+Image creation
+--------------
+
+The Zynq defconfig supports the Avnet ZedBoard. Use it to build the Barebox image::
+
+ make ARCH=arm zynq_defconfig
+ make ARCH=arm
+
+Create a FAT partition as the first partition of the SD card and copy the
+produced image ``images/barebox-avnet-zedboard.img`` into this partition.
+Rename the image to ``BOOT.bin`` which is the name the Primary Bootloader of the
+Zynq 7000 expects for the next stage.
+
+Bitstream loading
+-----------------
+
+The Zynq 7000 features an ARM Cortex-A9 processor (Processing System, PS)
+alongside a Programmable Logic (PL) component that functions as an FPGA. Barebox
+provides support for loading a bitstream into the PL through its firmware
+interface.
