We are planning to share more code between different NAND based devices (SPI NAND, OneNAND and raw NANDs), but before doing that we need to move the existing include/linux/mtd/nand.h file into include/linux/mtd/rawnand.h so we can later create a nand.h header containing all common structure and function prototypes.
