Rockpro64 PCI-Express Issue.

[pgwipeout]

So, I just patched my device tree to 

Code:

max-link-speed = <2>;

Now, I've got this:

Code:

root@rockpro64:~# lspci -vvv | grep Speed
               LnkCap: Port #0, Speed 5GT/s, Width x4, ASPM L1, Exit Latency L1 <8us
               LnkSta: Speed 5GT/s (ok), Width x4 (ok)
               LnkCtl2: Target Link Speed: 5GT/s, EnterCompliance- SpeedDis-
               LnkCap: Port #0, Speed 5GT/s, Width x8, ASPM L0s, Exit Latency L0s unlimited
               LnkSta: Speed 5GT/s (ok), Width x4 (downgraded)
               LnkCtl2: Target Link Speed: 5GT/s, EnterCompliance- SpeedDis-
               LnkCap: Port #0, Speed 5GT/s, Width x8, ASPM L0s, Exit Latency L0s unlimited
               LnkSta: Speed 5GT/s (ok), Width x4 (downgraded)

So yes, mainline needs to be fixed in a few places (I'll submit patches here shortly).
