		* 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). Most likely candidate for this is adding DPAA2 Ethernet
		driver support, which depends on drivers for several objects: DPNI,
		DPIO, DPMAC. Other pre-requisites include:

		* interrupt support. for meaningful driver support we need
		interrupts, and thus need message interrupt support by the bus
		driver.
		-Note: this has dependencies on generic MSI support work
		in process upstream, see [1] and [2].

		* Management Complex (MC) command serialization. locking mechanisms
		are needed by drivers to serialize commands sent to the MC, including
		from atomic context.

		* MC firmware uprev. The MC firmware upon which the fsl-mc
		bus driver and DPAA2 object drivers are based is continuing
		to evolve, so minor updates are needed to keep in sync with binary
