[PATCH 0/8] hw/arm: Add raspi[0123] acceptance tests

[PATCH 0/8] hw/arm: Add raspi[0123] acceptance tests

[Philippe Mathieu-Daudé]

- Add raspi0/raspi1 Linux boot tests
- Add raspi2/raspi3 U-Boot tests
- Add bcm2835 framebuffer test

I'll send another series moving these tests from boot_linux_console.py
to machine_arm_raspi.py, but this doesn't affect the review.

raspi0/raspi1 are based on "hw/arm: Add raspi0 and raspi1 machines".
Based-on: <20200215191543.3235-1-f4bug@amsat.org>

[PATCH 1/8] tests/acceptance/boot_linux_console: Use raspi console model as key

[Philippe Mathieu-Daudé]

Python dictionary are not that expensive. Use a key makes the
code easier to review.

[PATCH 8/8] tests/acceptance: Count Raspberry Pi logos displayed on framebuffer

[Philippe Mathieu-Daudé]

Add a test that verifies that each core properly displays the
Raspberry Pi logo on the framebuffer device.

We simply follow the OpenCV "Template Matching with Multiple Objects"
tutorial, replacing Lionel Messi by a raspberrry:
https://docs.opencv.org/4.2.0/d4/dc6/tutorial_py_template_matching.html

When OpenCV and NumPy are installed, this test can be run using:

  $ avocado --show=app,framebuffer run -t device:bcm2835-fb tests/acceptance/
  JOB ID     : 9bbbc54c0a6fa180348d0b5305507f76852b4da2
  JOB LOG    : avocado/job-results/job-2020-01-31T23.48-9bbbc54/job.log

  framebuffer: found raspberry at position (x, y) = (0, 0)
  framebuffer: found raspberry at position (x, y) = (71, 0)
  framebuffer: found raspberry at position (x, y) = (142, 0)
  framebuffer: found raspberry at position (x, y) = (213, 0)
  PASS (11.06 s)
  RESULTS    : PASS 1 | ERROR 0 | FAIL 0 | SKIP 0 | WARN 0 | INTERRUPT 0 | CANCEL 0
