   5           This is the framework for the SPI NOR which can be used by the SPI
   6           device drivers and the SPI-NOR device driver.

  14           Many flash memories support erasing small (4096 B) sectors. Depending
  15           on the usage this feature may provide performance gain in comparison
  16           to erasing whole blocks (32/64 KiB).
  17           Changing a small part of the flash's contents is usually faster with
  18           small sectors. On the other hand erasing should be faster when using
  19           64 KiB block instead of 16 × 4 KiB sectors.

  21           Please note that some tools/drivers/filesystems may not work with
  22           4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum).

  28           This enables support for the Quad SPI controller in master mode.
  29           We only connect the NOR to this controller now.
