  config MTD_SPI_NOR_USE_4K_SECTORS
  	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).

  	  This enables support for the Quad SPI controller in master mode.
  	  We only connect the NOR to this controller now.
