  mtd: eLBC NAND: remove elbc_fcm_ctrl->oob_poi
  NAND: Add -y option to nand scrub command
  NAND: Add nand read.raw and write.raw commands
  NAND: Really ignore bad blocks when scrubbing
  spl, nand: add 4bit HW ecc oob first nand_read_page function
  mxc_nand: fix a problem writing more than 32MB
