目前我自己配置的Linux，始终无法生成MTD。以下是正确的打印数据

[ 0.800710] dwmac-sun8i 1c30000.ethernet: PTP uses main clock
可以我的内核却无论如何也生成不出来。。。。。
我做了如何工作：
1 在uboot中添加了分区命令行。
#define CONFIG_BOOTCOMMAND "sf probe 0; " \
"sf read 0x41800000 0x100000 0x10000; " \
"sf read 0x41000000 0x110000 0x600000; " \
"bootz 0x41000000 - 0x41800000"
#define CONFIG_BOOTARGS "console=ttyS0,115200 earlyprintk panic=5 rootwait " \
"mtdparts=spi32766.0:1M(uboot)ro,64k(dtb)ro,6M(kernel)ro,-(rootfs) root=/dev/mtdblock3 rw rootfstype=jffs2"
2. 在arch/arm/boot/dts/sun8i-v3s-lichee-zero.dts中添加了以下内容：
&spi0 {
status ="okay";
w25q128bv:w25q128bv@0 {
compatible = "jedec,spi-nor";
reg = <0x0>;
spi-max-frequency = <50000000>;
#address-cells = <1>;
#size-cells = <1>;
};
};
3. 在内核中device drive->mtd support->Command line partition table parsing 选中
在内核中device drive->SPI support 进行了选中。
我按Zero的官方文档上的做了添加，却依然无法读到MTD相关参数。我不知道哪里出了错，希望有经验的朋友指教一二。多谢。
