Note: This test doesn't rely on boardenv_* configuration value but they can
change test behavior.

For example:

# Setup env__reset_test_skip to True if reset test is not possible or desired
# and should be skipped.
env__reset_test_skip = True

# Setup env__reset_test to set the bootmode if 'modeboot' u-boot environment
# variable is not set. Test will be skipped if bootmode is not set in both
# places i.e, boardenv and modeboot u-boot environment variable
env__reset_test = {
    'bootmode': 'qspiboot',
}

# This test will be also skipped if the bootmode is detected to JTAG.
