I use Qemu to run unit tests for a real-time operating system that runs on real 
Xilinx Zynq or Altera Cyclone-V for example.  Both systems use an ARM 
Cortex-A9MPCore with Security Extensions.  The operating system will run in 
secure mode all the time within a single address space and one-to-one mapped 
addresses.  Everything we use from this Security Extensions is the VBAR.  So 
for me the only missing Qemu feature is the VBAR if I want to use nearly the 
same binary on Qemu and the real hardware.
