Ok, so with the debug patch applied I let it running overnight and it
ran 39k+ times without PCI linkup failures.

I agree with your comments and now I am doing as you suggested:

Running top of tree u-boot-imx with only Tim's patch applied.

Then I do:

sudo minicom | tee pci.txt  to collect the logs.

After one hour of testing:

/tmp$ cat pci.txt | grep CPU | wc -l
2251

/tmp$ cat pci.txt | grep Bridge | wc -l
2251

Could you help testing the kernel patch?
