Hi Ahmad et al.

Just a quick update for you and the list.
I followed all your good suggestions and with this the PBL works and
loads barebox :-)

There are a few points on the TODO list I will address before posting a
v2, but just wanted to share the good news. No promises on the timeline
for an updated version - if anyone by chance would benefit from it
earlier then please let me know.
