Some flash chips which do not have a SFDP table supports Quad Input
Page Program. One of those chips is is25wp256, and this series has been
tested with that chip. If the spi controller supports quad mode then the
chip can use Quad Input Page Program to give a much better performance.

  mtd: spi-nor: extend no_sfdp_flags to use u16
  mtd: spi-nor: add support for Quad Page Program to no_sfdp_flags
  mtd: spi-nor: issi: is25wp256: Enable Quad Input Page Program
