本人采用的MicroPhase的Z7Lite板子，由于以太网控制器是定义在pl端的，所以寄存器地址什么的都不太一样。uboot要用petalinux生成，但是还是希望用源码就能编译，这样没有petalinux那么臃肿，而且编译速度快、配置灵活。我们可以考虑通过petalinux来生成源码与配置文件，从中挑选出重要内容，然后复制到uboot-xlnx源码目录里。以此来达到定制化配置uboot的效果，petalinux工程用一次就可以删掉了。
准备好交叉编译环境、xilinx的uboot官方源码。
利用xilinxSDK来生成设备树，具体参考：https://www.cnblogs.com/schips/p/xilinx-sdk-make-dtb-with-sdk-using.html xilinxSDK可以根据hdf文件来生成设备树。
复制设备树中所有dtsi与dts到uboot源码目录的arch/arm/dts/下，并且在system-top.dts最后加上
&axi_ethernet_0{
local-mac-address = [00 0a 35 00 03 22];
phy-handle = <&phy1>;
xlnx,has-mdio = <0x1>;
phy-mode = "mii";
mdio{
#address-cells = <1>;
#size-cells = <0>;
phy1:phy@1{
compatible = "realtek,rtl8201","ethernet-phy-id001c.c816";
device_type = "ethernet-phy";
reg = <0>;
};
};
};
利用在ubuntu16下的petalinux来生成工程，参考链接。最后配置文件就在/build/tmp/work/zynq-xxx-xilinx-linux/u-boot-xlnx/xxxxxxx/build/.config，将.config文件拷贝到uboot源码目录的configs文件夹下，并且改名为zynq_zzqbd_defconfig。
需要更改的地方主要是这里 CONFIG_DEFAULT_DEVICE_TREE="system-top"
petalinux生成的uboot源码下面多了两个文件，可以观察一下zynq_zzqbd_defconfig中的CONFIG_SYS_CONFIG_NAME。如果这个文件不拷贝，那么还是无法成功的。分别是platform-auto.h和platform-top.h。
并且我们主要在platform-auto.h中来配置uboot的环境。将这两个文件拷贝到./include/configs/下。
platform-top.h:
#include <configs/platform-auto.h>

#define DFU_ALT_INFO_RAM "dfu_ram_info=" "setenv dfu_alt_info " "image.ub ram $netstart 0x1e00000\0" "dfu_ram=run dfu_ram_info && dfu 0 ram 0\0" "thor_ram=run dfu_ram_info && thordown 0 ram 0\0"
