[U-Boot] u-boot vs. Cavium 5010 pci init

Hello, everyone,

Do you know what bugs or problems there are on u-boot with Cavium CN5010 PCI init? Now I have the following on the board with Cavium CN5010. The board will hang when PCI init with the U-boot. Any suggestions are welcome. How to identify if the issue's cause is HW or SW?

Thanks!
