QEMU changes
~~~~~~~~~~~~
- The ``runqemu`` script no longer systematically adds two serial ports
(``--serial null`` and ``-serial mon:stdio``) to the QEMU emulated machine
if the user already adds such ports through the ``QB_OPT_APPEND`` setting.
If the user adds one port, only ``--serial null`` is added, and
``-serial mon:stdio`` is no longer passed. If the user adds more than one
port, ``--serial null`` is no longer added either. This can break some
existing QEMU based configurations expecting such serial ports to be added
when ``runqemu`` is executed.
This change was made to avoid exceeding two serial ports, which interferes
with automated testing.
