This is the third and smallest of the SoC specific updates.
Changes include:
* SMP support for the Xilinx zynq platform
* Smaller imx changes
* LPAE support for mvebu
* Moving the orion5x, kirkwood, dove and mvebu platforms
to a common "mbus" driver for their internal devices.
It would be good to get feedback on the location of the "mbus"
driver. Since this is used on multiple platforms may potentially
get shared with other architectures (powerpc and arm64), it
was moved to drivers/bus/. We expect other similar drivers to
get moved to the same place in order to avoid creating more
top-level directories under drivers/ or cluttering up the
messy drivers/misc/ even more.
