+Subject: [PATCH 2/2] 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. 
+single binaries to be used between the two boards.
 
 Future work will incorporate the h3ulcb and Salvator boards into the
 abstraction.
