[Qemu-devel] [RFC PATCH v2 1/3] acceptance tests: Add SeaBIOS boot and debug console checking test

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

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 run tests/acceptance/boot_firmware.py
JOB ID     : 3dac2e738c941747ec01f043092b882a8370a92f
JOB LOG    : /home/phil/avocado/job-results/job-2018-10-03T19.42-3dac2e7/job.log
 (1/1) tests/acceptance/boot_firmware.py:BootFirmware.test_seabios: PASS (0.27 s)
RESULTS    : PASS 1 | ERROR 0 | FAIL 0 | SKIP 0 | WARN 0 | INTERRUPT 0 | CANCEL 0
JOB TIME   : 0.56 s
