Here's my suggestion how to convert the Avocado tests from
tests/avocado/boot_linux_console.py to the new functional framework:
Provide a LinuxKernelTest class in tests/functional/qemu_test/
so that the tests can be converted without too much modifications
(we just have to put them into separate files now, since each
file is run with a different qemu-system-target binary now).

Philippe Mathieu-Daudé (9):
  tests/functional: Convert mips64el Fuloong2e avocado test (2/2)
  tests/functional: Convert mips64el I6400 Malta avocado tests
  tests/functional: Convert mips64el 5KEc Malta avocado tests
  tests/functional: Convert mips32el Malta YAMON avocado test
  tests/functional: Convert nanomips Malta avocado tests
  tests/functional: Convert mips32eb 4Kc Malta avocado tests
  tests/functional: Convert ARM Raspi2 avocado tests
  tests/functional: Convert Aarch64 Raspi3 avocado tests
  tests/functional: Convert Aarch64 Raspi4 avocado tests

Thomas Huth (5):
  tests/functional: Add the LinuxKernelTest for testing the Linux boot
    process
  tests/functional: Convert the m68k Q800 Avocado test into a functional
    test
  tests/functional: Convert the Alpha Clipper Avocado test
  tests/functional: Convert the m68k MCF5208EVB Avocado test
  tests/functional: Convert the or1k-sim Avocado test
