Uboot dts的定义和适配
*************************

$TOPDIR/uboot/arch/arm/dts/hobot-j6e-evm.dts为我们对j6芯片uboot dts的参考配置，可根据该结合实际的硬件板卡修改生成专门的dts文件。参考dts如下：

.. code:: bash

	/dts-v1/;
	include "hobot-pinctrl-j6e.dtsi"

	...
	/ {
	compatible = "hobot,j6e-evm";
	model = "Horizon Robotics J6E Evaluation Module Board";
	...
