When Labgrid is used, it can get U-Boot ready for running tests. It prints a message when it has done so.

Add logic to detect this message and accept it.

Sometimes we know that the board is already running the right software, so provide an option to allow running of tests directly, without first resetting the board.

This saves time when re-running a test where only the Python code is changing.

When the connection to a board dies, assume it is dead forever until some user action is taken. Skip all remaining tests. This avoids CI runs taking an hour, with hundreds of 30-second timeouts all to no avail.

There is quite a bit of code in pytest to try to start up U-Boot on a board, with timeouts, expects, etc.

This is tedious to maintain and is peripheral to the test system's purpose. It seems better to put this logic in the lab itself, where is can provide such support.

With Labgrid we can use the UbootStrategy class to get the board into a useful state, however it needs to do it. Then it can report to pytest by writing a suitable string along with the U-Boot version it detected.

Add support for detecting 'lab mode' and simply assume that all is well in that case. Collect the version string when Labgrid says it is ready.
