Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20161004' into staging

target-arm queue:
 * Netduino 2 improvements (SPI, ADC devices)
 * fix some Mainstone key mappings
 * vmstateify tsc210x, tsc2005
 * virt: add 2.8 machine type
 * virt: support in-kernel GICv3 ITS
 * generic-loader device
 * A64: fix iss_sf decoding in disas_ld_lit
 * correctly handle 'sub pc, pc, 1' for ARMv6
