-The ADSP on Renesas SoCs required a reserved memory area to become
-enabled, and this needs to be done manually.
-
-This patch adds sound hardware abstraction information for the m3ulcb
-and m3ulcb-kf (kingfisher) device trees. This is helpful on-board the
-ADSP for dynamically determining sound hardware at runtime, allowing
-single binaries to be used between the two boards. 
-
-Future work will incorporate the h3ulcb and Salvator boards into the
-abstraction.
