menuconfig MTD_SPI_NOR
tristate "SPI-NOR device support"
depends on MTD
help
This is the framework for the SPI NOR which can be used by the SPI
device drivers and the SPI-NOR device driver.
if MTD_SPI_NOR
config MTD_SPI_NOR_USE_4K_SECTORS
bool "Use small 4096 B erase sectors"
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).
config SPI_CADENCE_QUADSPI
tristate "Cadence Quad SPI controller"
help
This enables support for the Cadence Quad SPI controller and NOR flash.
