# Released under the MIT license (see COPYING.MIT)
# This module adds support to testimage.bbclass to deploy images and run
# tests using a "master image" - this is a "known good" image that is
# installed onto the device as part of initial setup and will be booted into
# with no interaction; we can then use it to deploy the image to be tested
# to a second partition before running the tests.
#
# For an example master image, see core-image-testmaster
# (meta/recipes-extended/images/core-image-testmaster.bb)
