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