你的 dts/dtsi 没出问题来, spi 总线和 spi flash 都启用了,
看下你的 m25p80 驱动是否勾选？

把root=/dev/mtdblock3修改为root=31:03就可以了，有大神可以解释一下原因吗？

你应该还改了其他地方吧， 我看了前面的 kernel log 都没生成分区.
即使 bootargs 改成 root=31:03 我认为也是没用的。

Re: linux内核启动过程中没有看到分区标信息
终于找到了不生成分区的原因， 原来是使用了错误 SPI 驱动.
应该使用 CONFIG_SUN6I_SPI, 而不是 CONFIG_SUN4I_SPI
最迷惑的就是 u-boot 里面配置是对的， 而 linux kernel 的配置是错误的，
开始一直没有怀疑是这个问题,
直到参考 @chong 大神的 linux 4.19 才发现。
官方的配置文件 https://whycan.cn/files/members/3/lichee_nano_linux_config.zip (不是压缩文件，直接改后缀名即可!) 是有坑的.

Re: linux内核启动过程中没有看到分区标信息
果然有坑， 搜来搜去又搜到坑网,
应该是这样:
CONFIG_SPI_SUN6I
而不是这样:
CONFIG_SUN6I_SPI

还好终于把问题解决了， 都差点要卷铺盖了 ....

先学习了，很有用啊。话说，没有详尽的文档，始终是开发者最头疼的事情

Re: linux内核启动过程中没有看到分区标信息
配置SPI NAND之后，可以生成分区，但是就是无法挂载，好奇挂
