Dear TI，
我需要将DM8148配置成RC并识别出PCIe插槽上的WLAN卡。
硬件是基于Mistral的DM8148EVM设计的，PCIe这部分没有改动；内核代码版本是linux-2.6.37-psp04.01.00.06.patch2.
当我按照“TI81XX PSP PCI Express Root Complex Driver User Guide”设置完，内核进行Starting PCI scan后，依然出现No link/device.
调试信息如下：

会是什么原因呢？正常来讲，即使我的WLAN模块有问题，RC的PCI bridge也应该识别出来才对呀!
有没有人可以提供，正常的DM8148 PCIe RC bootup的log让我参考一下。
Thanks,
Jeffrey
