Somehow the class documentation has got out of sync with the generated entries.rst file. Regenerating it causes errors, so correct these and regenerate the entries.rst file.

When a file is removed by a commit (e.g. include/common.h yay!) it can cause incremental build failures since one of the dependency files from a previous build may mention the file.

Add an option to run 'make mrproper' automatically when a build fails. This can be used to automatically resolve the problem, without always adding the large overhead of 'make mrproper' to every build.

Buildman uses all available CPUs by default, so running more than one or two concurrent processes is not normally useful.

However in some CI cases we want to be able to run several jobs at once to save time. For example, in a lab situation we may want to run a test on 20 boards at a time, since only the build step actually takes much CPU.

Add an option which allows such a limit. When buildman starts up, it waits until the number of running processes goes below the limit, then claims a spot in the list. The list is maintained with a temporary file.

Note that the temp file is user-specific, since it is hard to create a locked temporary file which can be accessed by any user. In most cases, only one user is running jobs on a machine, so this should not matter.

Since commit 0dba45864b2a ("arm: Init the debug UART") the debug UART is set up in _main() before early_system_init() is called.

Add a suitable board_debug_uart_init() function to set up the UART in SPL.

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.

In Labgrid there is the concept of a 'role', which is similar to the U-Boot board ID in U-Boot's pytest subsystem.

The role indicates both the target and information about the U-Boot build to use. It can also provide any amount of other configuration. The information is obtained using the 'labgrid-client query' operation.

Make use of this in tests, so that only the role is required in gitlab and other situations. The board type and other things can be queried as needed.

Use a new 'u-boot-test-getrole' script to obtain the requested information.

With this it is possible to run lab tests in gitlab with just a single 'ROLE' variable for each board.

The tests currently catch a very board Exception in each case. This is thrown even in the event of a coding error.

We want to handle exceptions differently depending on their severity, so that we can avoid hour-long delays waiting for a board that is clearly broken.

As a first step, create some new exception types, separating out those which are simply an unexpected result from executed a command, from those which indicate some kind of hardware failure.

We expect commands to be echoed and this should happen quite quickly, since U-Boot is sitting at the prompt waiting for a command.

Reduce the timeout for this situation. Try to produce a more useful error message when something goes wrong. Also handle the case where the connection has gone away since the last command was issued.

There is a very annoying bug at present where the terminal echos part of the first command sent to the board. This happens because the terminal is still set to echo for a period until Labgrid starts up and can change this.

Fix this by disabling echo (and other terminal features) as soon as the spawn happens.
