我的SPI flash启动不起来，不知道为什么。。。。
[ 0.819749] m25p80 spi0.0: mx25l12805d (16384 Kbytes)
[ 0.824837] spi0.0: parser cmdlinepart: 0
[ 0.828928] spi0.0: parser ofpart: 0
以上是Log信息。也确认命令行内容是没有问题的。
却解析不出分区信息来。不知道为什么。

我照着文档对了一轮，menuconfig中没有问题，那些其他参数也都是对的。却查不到问题在哪里。。。。。真的是很坑爹。

嗯。连轮都轮不了。。。。。。因为我现在是用的新的板。公司的，把串口改到2去了。原来的，全部用不了。。。这才是最坑爹的地方。。。。

我重新下了4.13.版的源代码来编译，终于可以识别到分区了。可是不能正确引导。。。。。吐血。。。。前面的问题，经过对比，发现是dts的问题。
