Passing RUN_OPT settings via the shell environment is obsolet, as well
as the "--target uboot" expression. Instead please add:

  RUN_OPT += --include image/uboot

into your 'etc/build.conf' within your build directory. After triggering
a run-script e.g. 'make run/foo' an u-boot image 'var/run/foo/uImage'
will be created as result. You can transfer it by using u-boot via
sd-card, or network into the memory of your device, and finally load it
via u-boot's 'bootm' command.

BTW. the most useful documentation right now is the "Genode Foundations"
book that can be found on the website. In chapter 5 you will
find a lot of up-to-date information about system integration, booting
and testing, including the usage of our run-tool.
