RK3568 PCIE启动开启后，系统无法加载_问答

我们使用了PCIE，需要用到PCIE3.0x2 接2块SATA硬盘，参考 Rockchip_RK356X_Developer_Guide_PCIe_CN.pdf文档，我们配置好设备树及打开了对应的config选项。

系统启动就卡死在启动页面了，日志见kernel_pcie.log

初步定位下来开启了如下的3个选项就卡住了
CONFIG_PCIE_DW=y
CONFIG_PCIE_DW_HOST=y
CONFIG_PCIE_DW_ROCKCHIP=y
先关的设备树配置如下:

vcc3v3_pcie: gpio-regulator {
    compatible = "regulator-fixed";
    regulator-name = "vcc3v3_pcie";
    regulator-min-microvolt = <3300000>;
    regulator-max-microvolt = <3300000>;
    regulator-always-on;
    regulator-boot-on;    // 文档上说PCIE3.0拆成2个要配置为always 防止干扰，实际我们需要拉GPIO0_D4来控
    enable-active-high;
    gpio = <&gpio0 RK_PD4 GPIO_ACTIVE_HIGH>;
    startup-delay-us = <5000>;
    vin-supply = <&dc_12v>;
};
&pcie30phy {
    status = "okay";
};
&pcie3x1 {
    rockchip,bifurcation;
    reset-gpios = <&gpio3 RK_PA1 GPIO_ACTIVE_HIGH>;
    //vpcie3v3-supply = <&vcc3v3_pcie>;
    status = "disabled";
};
&pcie3x2 {
    rockchip,bifurcation;
    reset-gpios = <&gpio2 RK_PD6 GPIO_ACTIVE_HIGH>;
    //vpcie3v3-supply = <&vcc3v3_pcie>;
    status = "okay";
};
