This is a backport of the patches accepted to the Linux mainline related to
mvebu SoC (Armada XP and Armada 370) between Linux v3.11, and Linux v3.12.
This work mainly covers:

* Ground work for sharing the pxa nand driver(drivers/mtd/nand/pxa3xx_nand.c)
  between the PXA family,and the Armada family.
* Further updates to the mvebu MBus.
* Work and ground work for enabling MSI on the Armada family.
* some phy / mdio bus initialization related work.

+Subject: [PATCH 057/203] ARM: mvebu: Add BootROM to Armada 370/XP device tree
+
+In order to access the SoC BootROM, we need to declare a mapping
+(through a ranges property). The mbus driver will use this property
+to allocate a suitable address decoding window.
