# This module adds support to testimage.bbclass to deploy images and run
# tests on a Generic PC that boots using grub bootloader. The device must
# be set up as per README.hardware and the master image should be deployed
# onto the harddisk so that it boots into it by default.For booting into the
# image under test we interact with grub over serial, so for the
# Generic PC you will need an additional serial cable and device under test
# needs to have a serial interface. The separate ext3
# partition that will contain the image to be tested must be labelled
# "testrootfs" so that the deployment code below can find it.
