Great, thanks for testing them.

Do you know if it would be useful for your team to have the
lt-vexpress hwpack during the dev cycle? This hwpack can be used to
validate the work done at the lt tree before having the
topics/branches at linux-linaro.

If you're working directly with linux-linaro all the time, I'm also
happy with it, and we can just drop the lt flavor hwpack.
