Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20161028' into staging
target-arm queue:
* Fix reset GPIO handling for spitz, tosa boards
* virt: add 'pmu' property for configuring whether to expose the
vPMU to the guest
* char: cadence: correct reset value for baud rate registers
* versatilepb: do not run if user asks for more than 256MB RAM
* pxa2xx: Set value default values for CCCR and CKEN on PXA255
* arm: cubieboard: Add support for initrd
* i.MX: Fix GPIO ISR register write
