[PATCH v2 0/4] mtd: atmel_nand: enable Nand Flash Controller (NFC) support

[Josh Wu]

This patch series enable NFC support for SAMA5 soc. It can send command,
address cycles automaticly. Also when enable NFC sram, NFC will transfer
data to sram. Which can save lots of cpu time.

v1 --> v2:
 1) rebase it with latest l2-mtd git tree: 
    - remove useless nand commands (NAND_CMD_DEPLETE1, NAND_CMD_STATUS_ERRORx).
    - adopt to the new nand write function's parameters. Add error message when
      handle subpage write via nfc sram.
 2) rewrite pmecc_enable function. Now I use exist NAND_ECC_READ/WRITE const
    instead of using a new enum definition.

Josh Wu (4):
  mtd: atmel_nand: replace pmecc enable code with one function.
  mtd: atmel_nand: add Nand Flash Controller (NFC) support
  mtd: atmel_nand: enable Nand Flash Controller (NFC) read data via
    sram
  mtd: atmel_nand: enable Nand Flash Controller (NFC) write via sram
