+  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
+       interface changes to the MC.
