+
+    This target produces an image for
+    the `QEMU "virt" platform <https://www.qemu.org/docs/master/system/arm/virt.html>`_ using a 64 bit CPU type.
+
+    ARM targets differ from MIPS in that the kernel format expected
+    by QEMU is an "Image" (raw binary file) rather than an ELF
+    file, but this is taken care of by :command:`run.sh`. Check the
+    documentation for the :ref:`qemu` target for more information.
