    S29GL01GS U-boot and linux support

      Hello,

       

      I have a custom board that uses S29GL01GS Parallel NOR flash (128 MB) connected to imx6q processor through EIM bus.

      While booting I get the following error :

      of-flash 8000000.nor: do_map_probe() failed

       

      My linux kernel is 3.14.1.1.

      This is my device tree configuration:

       

      &weim {

              compatible = "fsl,imx6q-weim";

              reg = <0x021b8000 0x4000>;

              clocks = <&clks IMX6QDL_CLK_EIM_SLOW>;

              pinctrl-names = "default";

              pinctrl-0 = <&pinctrl_weim_nor_2 &pinctrl_weim_cs0_2>; 

              #address-cells = <2>;//see below:1 cell for 4 hex digits

              #size-cells = <1>;

                  ranges = <0 0 0x08000000 0x08000000>; 

              status = "okay";

       

                  nor@0,0 {

                  compatible = "cfi-flash";

                  reg = <0 0 0x04000000>;

                  #address-cells = <1>;

                  #size-cells = <1>;

                  bank-width = <2>;

                  fsl,weim-cs-timing = <0x10610281 0x00000001 0x0b020000

                      0x00008000 0x1c000000 0x00000000>;

       

                  };

          };

       

      Is there any patch to support this NOR flash?

       

      Thanks and regards,

      Sumish
