 realview-pbx-a9
 ===============
 
-TODO.
+The ``arm/realview_pbx_a9_qemu`` BSP is intended to be used with Qemu.  The
+Qemu ``realview-pbx-a9`` machine can be used to run SMP tests using for example
+the Qemu ``-smp 4`` command line option.
+
+The command line to execute an ELF file :file:`app.exe` on this Qemu machine
+is:
+
+.. code-block:: none
+
+    export QEMU_AUDIO_DRV="none"
+    qemu-system-arm -net none -nographic -M realview-pbx-a9 -m 256M -kernel app.exe
+
+You do not need to specify a device tree blob.
