      非常奇怪的现象
      T113-S3 SDC0 接EMMC
      SDC2 接 XR829
      在board.dts中一旦使能 （okay）SDC2，内核就无法启动了，disabled可以正常启动
      启动的时候SDIO CLK引脚会有一个短暂的时钟信号，CMD引脚也有短暂的时钟信号，然后内核就挂了

      我觉得是DTS文件有关SDC2的部分配置有问题，但是找不出问题在哪里

            @shanhai8372 SDC2使用的是v4p6x驱动，这个驱动是eMMC专用的，WIFI请使用v5p3x 驱动

            参考硬件 https://oshwhub.com/gloomyghost/yuzuki-rv-router
