You are missing some definitions, The #address-cells and #size-cells = <1>;
tis is a snippet of teh dts i defined for my board.
flash@0,0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "cfi-flash";
reg = <0x0 0x0 0x08000000>;
bank-width = <4>;
device-width = <1>;
/* set flash partition to correspond tu mtd parts in
u-boot*/
/* 0xf8000000 */
partition@0x0 {
label = "factory-image";
reg = <0x00000000 0x01000000>;
};
/* 0xf9000000 */
partition@0x01000000 {
label = "app-image-1";
reg = <0x01000000 0x01000000>;
};
