Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20170717' into staging
target-arm queue:
* new model of the ARM MPS2/MPS2+ FPGA based development board
* clean up DISAS_* exit conditions and fix various regressions
since commits e75449a346 8a6b28c7b5 (in particular including
ones which broke OP-TEE guests)
* make Cortex-M3 and M4 correctly default to 8 PMSA regions
