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

	bool "Use small 4096 B erase sectors"
	default y
	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).
