The big problem seems to be tests/functional/test_aarch64_sbsaref.py
which is creating a pair of 256 MB firmware files on every test
and not deleting them.

The tests/functional/test_arm_raspi2.py is also uncompressing some
archives and not deleting them.

Perhaps we need to define a standard "scratch dir" in the framework
that files can be put into, and then have the framework force delete
them at the end.

With regards,
Daniel
