# Functional test that boots a Linux kernel on an sx1 machine
# and checks the console. We have three variants:
#  * just boot initrd
#  * boot with filesystem on SD card
#  * boot from flash
# In all cases these images have a userspace that is configured
# to immediately reboot the system on successful boot, so we
# only need to wait for QEMU to exit (via -no-reboot).
