在移植内核nand flash分区部分时，在内核的启动过程中，看到分区部分的信息存在ftl_cs: FTL header not found.的问题，便通过查询相关资料解决该问题。在解决之前内核启动过程的信息如下：

标注红色字体的正是出现问题的部分，启动信息如上所示。
解决办法：
重新配置内核，取消下面三个选项（红色部分）。
在Make menuconfig时:
Device Drivers ->
Memory Technology Devices (MTD) ->
不要选择下面这三个选项
<>FTL (Flash Translation Layer) support
<> NFTL (NAND Flash Translation Layer) support
<>INFTL (Inverse NAND Flash Translation Layer) support
然后保存配置并重新编译即可。修改之后的的内核启动信息如下：
