		* Add README file (with ASCII art) describing relationships between
		DPAA2 objects and how combine them to make a NIC, an LS2 switch, etc.
		Also, define all acronyms used.

		* Decide if multiple root fsl-mc buses will be supported per Linux instance,
		and if so add support for this.

		* Add at least one device driver for a DPAA2 object (child device of the
		fsl-mc bus).

		Please send any patches to Greg Kroah-Hartman <greg@kroah.com>,
		devel@driverdev.osuosl.org, linux-kernel@vger.kernel.org
