This patchset adds support for spi-nand detection using parameter page.
This helps dealing with future JEDEC ID conflicts introduced by crazy
vendors. Also, the added ability to auto-detect chip capacity can help
reducing number of entries in our spi-nand id table.

Change since v1: extract common functions from raw nand

Chuanhong Guo (3):
  mtd: nand: extract some onfi functions to nandcore
  mtd: spinand: add support for detection with param page
  mtd: spinand: probe Winbond W25N01GV/W using param page
