[U-Boot] DUTS: missing pieces for a beginner

Oh, this is most welcome.

I guess there is no way I can deny this ;)

Looks ok to me, what is the question? ;)

A general warning - most of my recent changes went into making calling
duts more consistent with other Unix utilities.  Personally I think I
made good progress here, but if changes are needed here I am still open
for them.  That is one reason why I wasn't so sure on updating the docs
as the work is not completely finished.

> d) "./duts -d testsystems/ltp/ lt" shoud be rewritten to

Yes indeed.  I tried to have this '?' functionality for all possible
parameters to be able to inspect the possible values.

Please do - I'm more than happy to work with you in this respect.
Thanks in advance for tackling this job!

Indeed, I know.  If you take a look at the changes in git that we did in
recent months, you will notice that a lot of cleanup has already been
done making the code more transparent, but some areas are still way too
opaque.  I'm more than happy to change this however, as I _do_ know that
people will only start using and contributing once the design is somehow
easy to grasp.

So to answer your question - if you had a setup comparable to our VL,
you shouldn't need to modify anything.  But as you need to use other
commands to control power and connect to a board, you will need to
implement a new (what is currently called a) "context".

Clone config/self-hosted* to config/<whatever>* and work from there.
Then use "duts -c <whatever> sequoia" and dive in :)

The "context" stuff is definitely something we need to work on.  It
wasn't on my top-priority list as it currently works for us and
generalizations are only done correctly when we have multiple test
cases...
