[dpdk-dev,v3,02/15] eal/soc: add rte_eal_soc_register/unregister logic
Commit Message
Registeration of a SoC driver through a helper DRIVER_REGISTER_SOC
(on the lines of DRIVER_REGISTER_PCI). soc_driver_list stores all the
registered drivers.
Test case has been introduced to verify the registration and
deregistration.

It would deserve a dedicated thread to discuss legal sense of these things.
I'm not a lawyer but I think "All rights reserved." has no real sense.

From a layman (such as myself) perspective it indeed seems totally
ludicrous in the context of this particular license :) Whether it makes
more sense to lawyers I wouldn't know, but as for the background: it's
present in both 2- and 3-clause BSD licenses so *one* of them is
probably best left alone.
According to https://fedoraproject.org/wiki/Licensing:BSD, in the
3-clause BSD license "All rights reserved" is on a line of its own. In
the other variants it follows the copyright holder. So that's probably
where the duplicates originate from.
