target-arm queue:
 * enable 32-bit EL3 (TrustZone) for vexpress and virt boards
 * add fw_cfg device to virt board for UEFI firmware config
 * support passing commandline kernel/initrd to firmware

* remotes/pmaydell/tags/pull-target-arm-20141223: (31 commits)
  hw/arm/virt: enable passing of EFI-stubbed kernel to guest UEFI firmware
  hw/arm: pass pristine kernel image to guest firmware over fw_cfg
  hw/loader: split out load_image_gzipped_buffer()
  arm: add fw_cfg to "virt" board
  fw_cfg_mem: expose the "data_width" property with fw_cfg_init_mem_wide()
  fw_cfg_mem: introduce the "data_width" property
  exec: allows 8-byte accesses in subpage_ops
  fw_cfg_mem: flip ctl_mem_ops and data_mem_ops to DEVICE_BIG_ENDIAN
  fw_cfg_mem: max access size and region size are the same for data register
  fw_cfg: move boards to fw_cfg_init_io() / fw_cfg_init_mem()
  fw_cfg: hard separation between the MMIO and I/O port mappings
  target-arm: add cpu feature EL3 to CPUs with Security Extensions
  target-arm: Disable EL3 on unsupported machines
  target-arm: Breakout integratorcp and versatilepb cpu init
  target-arm: Set CPU has_el3 prop during virt init
  target-arm: Enable CPU has_el3 prop during VE init
  target-arm: Add arm_boot_info secure_boot control
  target-arm: Add ARMCPU secure property
  target-arm: Add feature unset function
  target-arm: Add virt machine secure property
  ...
