Its not a good situation, While it is good that both layers are maintained, it
should be clear in its purpose. It could be that github layer supports products
and might have binary stuff and may not work with latest upstreams and the
community layer while supporting lesser number of boards is kept uptodate
with respective upstreams. Ideally, it would be good if both layers were
in sync.
