[PATCH 00/17] add barebox in-tree testing infrastructure

[Ahmad Fatoum]

Commit 10948f86a3c5 ("watchdog: fix watchdog_set_timeout breakage for
drivers like imxwd") fixes an issue caught by a labgrid test suite
exercising functionality of a barebox release.

This could've been caught sooner if these tests were to run as part
of an automated _continuous_ testing process while sitting in next.

This series lays the ground work for that:

  - It commits to tree, machine readable YAML specification on how to
    build, emulate and test a number of defconfigs

  - It adds the glue required to configure tuxmake to build according
    to these configuration files

  - It extends the build system to allow calling labgrid-pytest
    on these files from within the tree

  - It adds a very basic self-test framework to allow for unit-testing
    barebox functionality

  - It adds a command line interface to tie this all together. Examples:
    ./test/emulate.pl virtio at efi_defconfig --emulate -- -device ?
    ./test/emulate.pl virtio at efi_defconfig --test -- --lg-log

The use of labgrid-pytest QEMUDriver's allows us in future the flexibility
to share tests between virtualized and physical targets. For now only
QEMUDriver-enabled targets are considered.

To demonstrate usage, this series imports the Linux printf selftest, which
is compiled into barebox and verified to run without errors by pytest.

Unless there are major issues, I'd appreciate if this series could get
merged first with changes happening gradually. This would allow writing
unit tests for new functionality in parallel.
