[Qemu-devel] [RFC PATCH 1/3] acceptance tests: Add SeaBIOS boot and debug console checking test

[Philippe Mathieu-Daudé]

This test boots SeaBIOS and check the debug console (I/O port on the ISA bus)
reports enough information on the initialized devices.

Example:

    $ avocado --show=debugcon run tests/acceptance/boot_firmware.py

- can we avoid the time.time() 2nd timeout check?

- can we avoid tempfile.mkdtemp() + shutil.rmtree() with Python2?
  (using context manager)
