Name starts with different letter to avoid typing ./ by mistake.

branch : qemu

again. It will not re-download QEMU, but unfortunately you will have to
recompile QEMU from scratch (which is very slow).
If you have changed only the ``eos`` files, to avoid a full recompilation
you may try a script similar to the following:
Alternative, slightly faster:
.. code:: shell
# from the qemu directory
If you have changed only the ``eos`` files (i.e. no changes to QEMU core),
use the following command; afterwards, recompilation will be very fast:
cp -v $ML_PATH/contrib/qemu/eos/* $QEMU_PATH/hw/eos/
cp -v $ML_PATH/contrib/qemu/eos/mpu_spells/* $QEMU_PATH/hw/eos/mpu_spells/
