config SPI_FLASH_USE_4K_SECTORS
bool "Use small 4096 B erase sectors"
depends on SPI_FLASH
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).
