Pali, I tested this series with Compex WLE900VX and with a ASMedia SATA card.
Both are visible with these patches.
But if I enable the pci-driver in U-Boot, kernel reports "link never came up" fo the WLE900VX card. The SATA card works in this case.

We should try to somehow reset the whole PCIe controller in Linux. There are the PCIe Core Warm Reset and PCIe PHY Warm Reset register. I also think that maybe we should try to reset the whole PCI comphy.
