   9 Commit 1b47b98acce2 ("ARM: BCM5301X: Add DT entry for SPI controller and
  10 NOR flash") enabled SPI-NOR device on routers using serial flash only.
  11 However there are also devices with two flash memories:
  12 1) Small SPI attached flash used mostly for booting
  13 2) Bigger NAND used mostly for storing firmware
  14 On such devices we still need SPI-NOR e.g. to access NVRAM data.
