按照log来说驱动加载并没有问题。只是没有识别到pcie设备

以下是dmesg中的pci信息，怀疑是不是能够给其他PCIe设备分配的内存不够导致的。

解决方法可以说一下吗？
pci 0000:01:00.0: BAR 2: no space for [mem size 0x02000000]，看这一句，主要是rk3588的pcie低端bar内存大小只有16MB，对端FPGA把内存配置减小就好了
请问您做的是itx 3588j和fpga板卡通过pcie互联嘛，我想咨询一下3588开发板的pcie的endpoint模式切换能不能实现，通过rk3588官方的修改dts就可以吗

dts没有修改，主要是FPGA那边进行适配，你要看一下3588的dts文件，最大能支持多少的内存

我看了下，我这里 fpga 所在的 pci 01:00.0 是分配了的，1K*32b 正好是 0x3ff，但是 pci 00:00.0 有问题，这各是rk3588自己的东西吧，影响吗？
