Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20160606-1' into staging

target-arm queue:
 * support instruction syndrome info for data aborts from A64 to EL2
 * add HSTR_EL2 register
 * fix incorrect ESR IL bits in various syndrome register cases
 * virt: fix limit of 64-bit ACPI/ECAM PCI MMIO range
 * gicv2: RAZ/WI non-sec access to sec interrupts
 * i2c: add aspeed i2c controller
 * virt: Reject gic-version=host for non-KVM (don't segv on aarch64 host)
 * xlnx-zynqmp: Add a secure prop to en/disable ARM Security Extensions
 * xlnx-zynqmp: Support KVM on AArch64 hosts
 * ptimer: Various fixes for awkward corner cases
 * char: QOMify various ARM UART models
 * char: get rid of qemu_char_get_next_serial
 * target-arm: Fix TTBR selecting logic on AArch32 Stage 2 translation
 * zynqmp: Add the ZCU102 board
