On Armada 38x it is possible to get the SoC Id and the revision without using the PCI register. Accessing the PCI registers implies enabling its clock and, because of the initialization issue, not keeping them enable. So if possible it is better to avoid it. Armada 370 and Armada XP provides the SoC ID values from the system controller but not the revision. Armada 375 provides both but the SoC ID value looks buggy (0x6660 instead of 0x6720).
