We need the first batch of SoC changes for the net part and then the
second batch depends on those net changes. Also: dragging the merge
for this over a year is a bit overkill.

Sekhar: I know you're usually provided with immutable branches from
framework maintainers for the SoC changes - is it ok for you to
provide the net maintainers with an immutable branch after applying
the first part of davinci board file changes?
