- 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"
- 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).
- config SPI_FSL_QUADSPI
- tristate "Freescale Quad SPI controller"
- depends on ARCH_MXC || COMPILE_TEST
- depends on HAS_IOMEM
- help
- This enables support for the Quad SPI controller in master mode.
- This controller does not support generic SPI. It only supports
- SPI NOR.
- config SPI_NXP_SPIFI
- tristate "NXP SPI Flash Interface (SPIFI)"
- depends on OF && (ARCH_LPC18XX || COMPILE_TEST)
- depends on HAS_IOMEM
- help
- Enable support for the NXP LPC SPI Flash Interface controller.
- SPIFI is a specialized controller for connecting serial SPI
- Flash. Enable this option if you have a device with a SPIFI
- controller and want to access the Flash as a mtd device.
