+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.
