of: Allows to use the PCI translator without the PCI core Translating an address from a PCI node of the device-tree into a CPU physical address doesn't require the core PCI support. Those translations are just related to the device tree itself. The use case to translate an address from a PCI node without actually using the PCI core support is when one needs to access the PCI controller without accessing any PCI devices. Marvell SoCs, such as Kirkwood, Dove or Armada XP for instance, come with an IP of a PCI controller. In the registers of this controller are stored the ID and the revision of a SoC. With this patch it will be possible to read the SoC ID of a board without any PCI device and then without the PCI core support.
