     * Freescale PQ3 and QorIQ based Cache SRAM
     
     Freescale's mpc85xx and some QorIQ platforms provide an
     option of configuring a part of (or full) cache memory
     as SRAM. This cache SRAM representation in the device
     tree should be done as under:-
     
     Required properties:
     
    - compatible : should be "fsl,p2020-cache-sram"
    - fsl,cache-sram-ctlr-handle : points to the L2 controller
    - reg : offset and length of the cache-sram.
    
    Example:
    
    cache-sram@fff00000 {
            fsl,cache-sram-ctlr-handle = <&L2>;
            reg = <0 0xfff00000 0 0x10000>;
            compatible = "fsl,p2020-cache-sram";
    };
