+This is the buildroot board support for the Avnet Microzed. The Microzed is
+a development board based on the Xilinx Zynq-7000 based All-Programmable
+System-On-Chip.
+
+Microzed information including schematics, reference designs, and manuals are
+available from http://www.zedboard.org .
+
+Steps to create a working system for Microzed:
+
+1) make microzed_defconfig
+2) make
+3) copy files BOOT.BIN, u-boot-dtb.img, rootfs.cpio.uboot,
+ uImage, zynq-zed.dtb into your SD card
+4) boot your Microzed
+
+The expected output:
+
+ U-Boot SPL 2015.07 (Sep 15 2015 - 16:10:56)
+ mmc boot
+ reading system.dtb
+ spl_load_image_fat_os: error reading image system.dtb, err - -1
+ reading u-boot-dtb.img
+ reading u-boot-dtb.img
+
+
+ U-Boot 2015.07 (Sep 15 2015 - 16:10:56 +0200)
+
+ Model: Zynq MicroZED Board
+ I2C: ready
+ DRAM: ECC disabled 1 GiB
+ MMC: zynq_sdhci: 0
+ Using default environment
+ ...
+
+When using an older U-Boot then 2015.07, a working ps7_init.c
+file is required to be installed into the U-Boot directory
+structure. From 2015.07, the major Zynq-based boards are
+supported without any manual intervention.
+
+Resulting system
+----------------
+A FAT32 partition should be created at the beginning of the SD Card
+and the following files should be installed:
+ /BOOT.BIN
+ /zynq-zed.dtb
+ /uImage
+ /rootfs-cpio.uboot
+ /u-boot-dtb.img
+
+All needed files can be taken from output/images/
+
+BOOT.BIN, uImage and u-boot-dtb.img are direct copies of the same files
+available on output/images/.
+
+Note th at the DTB (zynq-zed.dtb) is the same as the one used for the
+Zedboard, and that this is the recommended solution, see
+https://forums.xilinx.com/t5/Embedded-Linux/Microzed-default-device-tree-dts/td-p/432856.
+
+There is a patch attached that redefines the U-Boot's environment
+to work with Buildroot out-of-the-box.
+
+You can alter the booting procedure by creating a file uEnv.txt
+in the root of the SD card. It is a plain text file in format
+<key>=<value> one per line:
+
+kernel_image=myimage
+modeboot=myboot
+myboot=...
