缘起：让天启AIO-3576Q38开发板在天启Buildroot下适配uart2m1

当你把荣品RD-RK3588开发板重新适配一把，就相当于从头做了一个项目：【荣品RD-RK3588开发板】。
当然，开发板的功能都是好的，你免除了调试的过程，也就没有解决相关硬件出错的经验/机会了！

1、
Z:\Linux_SDK\Firefly_SDK\kernel\arch\arm64\boot\dts\rockchip\rk3576-firefly-aio-3576q38.dtsi

//#if GMAC1
//&gmac1 {
// snps,reset-gpio = <&gpio0 RK_PD1 GPIO_ACTIVE_LOW>;
// tx_delay = <0x1b>;
// pinctrl-names = "default";
// pinctrl-0 = <&eth1m0_miim
// &eth1m0_tx_bus2
// &eth1m0_rx_bus2
// &eth1m0_rgmii_clk
// &eth1m0_rgmii_bus>;
//};
//#endif

#if CAN1
&can1 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&can1m1_pins>;
};
#endif

// 2026/1/28 10:07 wenyuanbo add
&uart2 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&uart2m1_xfer>;
};

#if RS232
&uart6 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&uart6m0_xfer>;
};
#endif

#if RS485
&uart10 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&uart10m2_xfer>;
};
#endif
