Right, but "available" is not the same as "open" unfortunately. Being
able to study the source is better than nothing, but it is a far cry
from having the ability to modify it and, most importantly, publish
those changes.

So, to restate my question more precisely: Can we expect that Marvell
will provide CPSS under a license that is compatible with the Linux
kernel?

If that is not possible, will Marvell at least commit to allow the
publishing of drivers developed from functional specifications and other
chip documentation?

Yes, but it makes it hard for smaller players to get on the ride early.

Totally fair. That problem should be solvable by some kind of taint
concept though. Presumably you have this problem already with the
existing SDK model? Customers can build things on top of CPSS that are
broken in a million ways.
