I have a device with a SPI NOR flash and I want to place there u-boot, kernel and rootfs.
To do so I’ve added partitions in th devicetree:

&spi0 {
    pinctrl-names = "default";
    pinctrl-0 = <&spi0_pc_pins>;
    status = "okay";

    flash@0 {
        #address-cells = <1>;
        #size-cells = <1>;
        compatible = "winbond,w25q128", "jedec,spi-nor";
        reg = <0>;
        spi-max-frequency = <40000000>;

        partition@0 {
            label = "u-boot";
            reg = <0x000000 0x80000>;
        };

        partition@80000 {
            label = "boot";
            reg = <0x80000 0x680000>;
        };

        partition@680000 {
            label = "rootfs";
            reg = <0x680000 0x1000000>;
        };
    };
};

Then I’ve extended the u-boot config. It might have unnecessary options, but during the development I’m trying different options to achive my goal

CONFIG_MTD_BLKDEVS=y

CONFIG_DOS_PARTITION=y

u-boot starts but can’t boot anything, because it doesn’t see any partitions of the spi device

Do you have any idea what have I missed?
