Broadcom's interpretation of these comments is that they don't contradict
the GPL.

OCP is basically ISA on steroids - no configuration space, no nothing so
there is not terribly much OCP code that could potencially be shared.
Right now we treat OCP devices such as on PMC-Sierra's RM9000 series as
platform devices.

I'm clearly less than impressed by OCP ...
