I just sent v3 of the u-boot-test-hooks series. That needs to be in
for Labgrid to work.

The only other series is [1] which makes the integration nicer, but is
not necessary. That makes sense since we still want the lab to be able
to test older commits.

>From that series patch [2] fixes a problem which breaks pytest runs,
since without it, pytest gets a double echo of a few of the characters
of the first command it sends. It is a pretty annoying problem which
took a while to figure out. I tried very hard to fix it without
patching U-Boot's pytest code, but I gave up. One thought I just had
is that it is possible that setting up the terminal in the
u-boot-test-console script might work most of the time, i.e. before
calling Labgrid.
