器件型号：DP83867CR 您好、TI 团队：
我们将 Phy DP83867与 RZG2UL 一起使用、在 u-boot 中启用它时遇到问题。
设置这些文件、在 u-boot 配置下、
CONFIG_PHY=y CONFIG_PHY_TI=y CONFIG_PHY_TI_DP83867=y CONFIG_MII=y CONFIG_DM_ETH_PHY=y CONFIG_PHY_FIXED=y CONFIG_CMD_NET=y CONFIG_NET_RANDOM_ETHADDR=y CONFIG_BITBANGMII=y CONFIG_DM_ETH=y
DTS 节点如下。

pinctrl-names = "default";
phy-handle = <ðphy0>;
phy-mode = "rgmii-id";
status = "okay";

请指导我们如何在 u-boot 中启用 PHY。
谢谢。此致。
