+Subject: [PATCH 666/725] arm: dts: Improve the bcm27xx inclusion hierarchy
+
+1) The top-level .dts files now include parallel chains of bcm27xx.dtsi
+   and bcm27xx-rpi.dtsi files, with no cross-inclusion between the two
+   chains.
+
+2) Move definitions and deletions to the point of maximum commonality
+   to reduce redundancy.
