  13         help
  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).

  40           Cadence QSPI is a specialized controller for connecting an SPI
  41           Flash over 1/2/4-bit wide bus. Enable this option if you have a
