Is this still an issue?

That is fine.

This is the problem.  Check:

	pcie_configured = is_serdes_configured(PCIE1);
	if (pcie_configured && !(devdisr & MPC85xx_DEVDISR_PCIE))

in your board file.

This is a code bug, it really should say is PCI1 and not PCIE1.

You need to figure out why "PCIE1: disabled" is occurring
