This is a backport of the patches accepted to the Linux mainline related to
mvebu SoC (Armada XP and Armada 370) between Linux v3.12, and Linux v3.13.
This work mainly covers:

* Finishes work for sharing the pxa nand driver(drivers/mtd/nand/pxa3xx_nand.c)
  between the PXA family, and the Armada family.
* timer initialization update, and access function for the Armada family.
* Generic IRQ handling backporting.
* Some bug fixes.

+Subject: [PATCH 173/203] ARM: mvebu: Add the reference 25 MHz fixed-clock to
+ Armada XP
+
+The Armada XP SoC has a reference 25 MHz fixed-clock that is used in
+some controllers such as the timer and the watchdog. This commit adds
+a DT representation of this clock through a fixed-clock compatible node.
