OpenWRT中添加新设备支持

这里还是向OpenWRT中添加对小度路由的支持
向 target/linux/ramips/image/makefile中写入新设备

image/build/profile/mt7620a_CLZ=$(call buildFirmware/Default8M/$(1),$(1),mt7620a_clz,MT7620a_CLZ)
$(call image/Build/Profile/MT7620a_CLZ,$(1))

base-files中的一些可用配置：

base-files/etc/diag.sh 控制LED在OpenWRT启动时是否闪烁
base-files/lib/upgrade/platform.sh 允许sysupgrade工作
base-files/etc/uci-defaults/network to configure(安装) default network interface(界面) settings, particularly MAC addresses
base-files/etc/uci-defaults/leds if you have configurable(可配置的) LEDs which should default to a behavior(行为), like a WLAN activity LED
base-files/etc/hotplug.d/firmware(固件)/10-rt2x00-eeprom to extract(提取) the firmware image for the wireless(无线的) module
base-files/lib/preinit/06_set_iface_mac to set the MAC addresses of any other interfaces(界面)

编写的小度路由用的dts文件

/dts-v1/;

/include/ "mt7620a.dtsi"

/ {
    compatible = "ralink,mt7620a-eval-board", "ralink,mt7620a-soc";
    model = "Ralink MT7620A xiaodu board";

    palmbus@10000000 {
        sysc@0 {
            ralink,gpiomux = "i2c";
            ralink,uartmux = "gpio";
            ralink,wdtmux = <1>;
        };

        gpio0: gpio@600 {
            status = "okay";
        };

        spi@b00 {
            status = "okay";

            w25q64bv@0 {
                #address-cells = <1>;
                #size-cells = <1>;
                compatible = "w25q64bv";
                reg = <0 0>;
                linux,modalias = "w25q64bv";
                spi-max-frequency = <1000000>;

                partition@0 {
                    label = "u-boot";
                    reg = <0x0 0x30000>;
                    read-only;
                };

                partition@30000 {
                    label = "u-boot-env";
                    reg = <0x30000 0x10000>;
                    read-only;
                };

                factory: partition@40000 {
                    label = "factory";
                    reg = <0x40000 0x10000>;
                    read-only;
                };

                partition@50000 {
                    label = "firmware";
                    reg = <0x50000 0x6b0000>;
                };

                partition@700000 {
                    label = "usercfg";
                    reg = <0x700000 0x100000>;
                };
            };
        };
    };

    ethernet@10100000 {
        status = "okay";

        pinctrl-names = "default";
        pinctrl-0 = <&ephy_pins>;

        ralink,port-map = "llllw";
    };

    gsw@10110000 {
        ralink,port4 = "ephy";
    };

    sdhci@10130000 {
        status = "okay";
    };

    pcie@10140000 {
        status = "okay";
    };

    gpio-keys-polled {
        compatible = "gpio-keys";
        #address-cells = <1>;
        #size-cells = <0>;
        poll-interval = <20>;
        wps {
            label = "wps";
            gpios = <&gpio0 12 1>;
            linux,code = <0x100>;
        };
        reset {
            label = "reset";
            gpios = <&gpio0 13 1>;
            linux,code = <0x101>;
        };
    };
};

添加设备后，最好需要将之前编译产生的临时文件删除，语句如下

 cd trunk
 rm -rf tmp
 make menuconfig
