  14           This enables access to SPI NOR flash, using MT81xx SPI NOR flash
  15           controller. This controller does not support generic SPI BUS, it only

  21         help
  22           Many flash memories support erasing small (4096 B) sectors. Depending
  23           on the usage this feature may provide performance gain in comparison
  24           to erasing whole blocks (32/64 KiB).
  25           Changing a small part of the flash's contents is usually faster with
  26           small sectors. On the other hand erasing should be faster when using
  27           64 KiB block instead of 16 × 4 KiB sectors.
  28
  29           Please note that some tools/drivers/filesystems may not work with
  30           4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum).
