-+	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 small part of flash content 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).
