MTD partition support #5

Closed twu2 closed 5 years ago

twu2 commented 5 years ago

add following setting in device tree will make MTD work (u-boot, u-boot environment partition).

&ecspi1 { fsl,spi-num-chipselects = <2>; cs-gpios = <&gpio2 30 GPIO_ACTIVE_HIGH>, <&gpio3 19 GPIO_ACTIVE_HIGH>; pinctrl-names = "default"; pinctrl-0 = <&pinctrl_ecspi1>; status = "okay";

    flash: m25p80@0 {
    #address-cells = <1>;
    #size-cells = <1>;
            compatible = "m25p80", "jedec,spi-nor";
            spi-max-frequency = <20000000>;
            reg = <0>;

            partition@0 {
                    label = "uboot";
                    reg = <0x0 0xc0000>;
            };

            partition@c0000 {
                    label = "uboot environment";
                    reg = <0xc0000 0x40000>;
            };

            partition@100000 {
                    label = "reserved";
                    reg = <0x100000 0x100000>;
            };
   };

};

Latest branch 5.2.8 has the MTD partitions visible in Linux.
