+Freescale L2 Cache Controller
+
+L2 cache is present in Freescale's QorIQ and QorIQ Qonverge platforms.
+The cache bindings explained below are ePAPR compliant
+
+Required Properties:
+
+- compatible	: Should include "fsl,chip-l2-cache-controller" and "cache"
+		  where chip is the processor (bsc9132, npc8572 etc.)
+- reg		: Address and size of L2 cache controller registers
+- cache-size	: Size of the entire L2 cache
+- interrupts	: Error interrupt of L2 controller
+- cache-line-size : Size of L2 cache lines
+
+Example:
+
+	L2: l2-cache-controller at 20000 {
+		compatible = "fsl,bsc9132-l2-cache-controller", "cache";
+		reg = <0x20000 0x1000>;
+		cache-line-size = <32>; // 32 bytes
+		cache-size = <0x40000>; // L2,256K
+		interrupts = <16 2 1 0>;
+	};

+Freescale DDR memory controller
+
+Properties:

+- compatible	: Should include "fsl,chip-memory-controller" where
