Current code sets the mtd->type with MTD_NANDFLASH for both SLC and MLC. So the jffs2 may supports the MLC nand, but in actually, the jffs2 should not support the MLC. This patch uses the nand_is_slc() to check the nand cell type, and set the mtd->type with the right nand type. After this patch, the jffs2 only can support the SLC nand.
