[PATCH 6/8] tests/boot_linux_console: Test booting U-Boot on the Raspberry Pi 2

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

This test runs U-Boot on the Raspberry Pi 2.
It is very simple and fast:

  $ avocado --show=app,console run -t raspi2 -t u-boot tests/acceptance/
  JOB LOG    : avocado/job-results/job-2020-01-20T23.40-2424777/job.log

U-Boot is built by the Debian project, see:
