Android 内核 yaffs2文件系统 不能包含

Yaff2文件系统支持的位置:

File system---> Miscellaneous filesystems ---> YAFFS2 file system support  <M>

Yaffs2文件系统依赖于MTD_BLOCK,所以需要先选上 Y,默认为M

Device Drivers -> Memory Technology Device (MTD) support -> Caching block device access to MTD devices

而MTD_CHAR对应的选项为：

Device Drivers -> Memory Technology Device (MTD) support -> Direct char device access to MTD devices
