  • Chipselect/Local Bus

Properties:

  • name : Should be localbus
  • #address-cells : Should be either two or three. The first cell is the
                 chipselect number, and the remaining cells are the
                 offset into the chipselect.
    
  • #size-cells : Either one or two, depending on how large each chipselect
              can be.
    
  • ranges : Each range corresponds to a single chipselect, and cover
         the entire access window as configured.
    

Example:
localbus@f0010100 {
compatible = “fsl,mpc8272-localbus”,
“fsl,pq2-localbus”;
#address-cells = <2>;
#size-cells = <1>;
reg = <f0010100 40>;

    ranges = <0 0 fe000000 02000000
          1 0 f4500000 00008000>;

    flash@0,0 {
        compatible = "jedec-flash";
        reg = <0 0 2000000>;
        bank-width = <4>;
        device-width = <1>;
    };

    board-control@1,0 {
        reg = <1 0 20>;
        compatible = "fsl,mpc8272ads-bcsr";
    };
};
