+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@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
+                 chip is the processor (bsc9132, mpc8572 etc.), or
+                 "fsl,qoriq-memory-controller".
+- reg          : Address and size of DDR controller registers
+- interrupts   : Error interrupt of DDR controller
+
+Example 1:
+
+       memory-controller@2000 {
+               compatible = "fsl,bsc9132-memory-controller";
+               reg = <0x2000 0x1000>;
+               interrupts = <16 2 1 8>;
+       };
+
+
+Example 2:
+
+       ddr1: memory-controller@8000 {
+               compatible = "fsl,qoriq-memory-controller-v4.7",
+                               "fsl,qoriq-memory-controller";
+               reg = <0x8000 0x1000>;
+               interrupts = <16 2 1 23>;
+       };
