Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20150908' into staging

target-arm queue:
 * Implement priority handling properly via GICC_APR
 * Enable TZ extensions on the GIC if we're using them
 * Minor preparatory patches for EL3 support
 * cadence_gem: Correct Marvell PHY SPCFC reset value
 * Support AHCI in ZynqMP

* remotes/pmaydell/tags/pull-target-arm-20150908:
  xlnx-zynqmp: Connect the sysbus AHCI to ZynqMP
  xlnx-zynqmp.c: Convert some of the error_propagate() calls to error_abort
  ahci.c: Don't assume AHCIState's parent is AHCIPCIState
  ahci: Separate the AHCI state structure into the header
  cadence_gem: Correct Marvell PHY SPCFC reset value
  target-arm: Add AArch64 access to PAR_EL1
  target-arm: Correct opc1 for AT_S12Exx
  target-arm: Log the target EL when taking exceptions
  target-arm: Fix default_exception_el() function for the case when EL3 is not supported
  hw/arm/virt: Enable TZ extensions on the GIC if we are using them
  hw/arm/virt: Default to not providing TrustZone support
  hw/cpu/{a15mpcore, a9mpcore}: enable TrustZone in GIC if it is enabled in CPUs
  hw/intc/arm_gic_common: Configure IRQs as NS if doing direct NS kernel boot
  hw/arm: new interface for devices which need to behave differently for kernel boot
  qom: Add recursive version of object_child_for_each
  hw/intc/arm_gic: Actually set the active bits for active interrupts
  hw/intc/arm_gic: Drop running_irq and last_active arrays
  hw/intc/arm_gic: Fix handling of GICC_APR<n>, GICC_NSAPR<n> registers
  hw/intc/arm_gic: Running priority is group priority, not full priority
  armv7m_nvic: Implement ICSR without using internal GIC state
