Depending 18 on the usage this feature may provide performance gain in comparison 19 to erasing whole blocks (32/64 KiB). 20 Changing a small part of the flash's contents is usually faster with 21 small sectors. On the other hand erasing should be faster when using 22 64 KiB block instead of 16 × 4 KiB sectors. 23 24 Please note that some tools/drivers/filesystems may not work with 25 4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum). 26 27source "drivers/mtd/spi-nor/controllers/Kconfig" 28 29endif # MTD_SPI_NOR 30
