This work mainly covers:

* Enabling USB storage, and PCI to mvebu_defconfig.
* Add support for NOR flash.
* Some PCI device tree related updates, and bus parsing.
* Adding Armada XP & 370 PCI driver, and update some clock gating
  specifics.

+Subject: [PATCH 048/203] PCI: mvebu: Check valid base address before port
+ setup
+
+This driver does not fail to probe when it cannot obtain
+a port base address. Therefore, add a check for NULL base address
+before setting up the port, which prevents a kernel panic in such
+cases.
