"""
Test the bootstage command.

It is used for checking the boot progress and timing by printing the bootstage
report, stashes the data into memory and unstashes the data from memory.

Note: This test relies on boardenv_* containing configuration values to define
the data size, memory address, and bootstage magic address (defined in
common/bootstage.c). Without this, bootstage stash and unstash tests will be
automatically skipped.

For example:

.. code-block:: python

    env__bootstage_cmd_file = {
        'addr': 0x200000,
        'size': 0x1000,
        'bootstage_magic_addr': 0xb00757a3,
    }
