zynq在邏輯段加入了一個RC， 設備樹如下：
axi-pcie@50000000 {
#address-cells = <0x3>;
#interrupt-cells = <0x1>;
#size-cells = <0x2>;
compatible = "xlnx,axi-pcie-host-1.00.a";
device_type = "pci";
interrupt-parent = <0x3>;
interrupts = <0x0 0x1d 0x4>;
interrupt-map = <0 0 0 1 &pcie_intc 1>,
<0 0 0 2 &pcie_intc 2>,
<0 0 0 3 &pcie_intc 3>,
<0 0 0 4 &pcie_intc 4>;
interrupt-map-mask = <0x0 0x0 0x0 0x7>;
bus-range = <0x00 0xff>;
ranges = <0x2000000 0x0 0x60000000 0x60000000 0x0 0x10000000>;
reg = <0x50000000 0x1000000>;
pcie_intc: interrupt-controller {
interrupt-controller;
#address-cells = <0>;
#interrupt-cells = <1>;
};
};內核打印錯誤如下：

分析代碼是設備類型設置錯誤。
需要在邏輯的工程中，修改class code。 （class-code = <0x60400>）
