97171ad70e ARM: mvebu: Enable mvebu-soc-id on Kirkwood 
Add the Kirkwood PCIe compatibility string to mvebu-soc-id, so that it
can get the SoC ID and revision from the PCIe endpoints.

dc4910d9e9 ARM: mvebu: Fix kernel hang in mvebu_soc_id_init() when of_iomap failed 
When pci_base is accessed whereas it has not been properly mapped by
of_iomap() the kernel hang. The check of this pointer made an improper
use of IS_ERR() instead of comparing to NULL. This patch fix this
issue.

af8d1c63af ARM: mvebu: Add support to get the ID and the revision of a SoC 
All the mvebu SoCs have information related to their variant and
revision that can be read from the PCI control register.

This patch adds support for Armada XP and Armada 370. This reading of
the revision and the ID are done before the PCI initialization to
avoid any conflicts. Once these data are retrieved, the resources are
freed to let the PCI subsystem use it.
