- help
- This is the framework for the SPI NOR which can be used by the SPI
- device drivers and the SPI-NOR device driver.

- tristate "Mediatek MT81xx SPI NOR flash controller"
- depends on HAS_IOMEM
- help
- This enables access to SPI NOR flash, using MT81xx SPI NOR flash
- controller. This controller does not support generic SPI BUS, it only
- supports SPI NOR Flash.
- 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_ATMEL_QUADSPI
- tristate "Atmel Quad SPI Controller"
- depends on ARCH_AT91 || (ARM && COMPILE_TEST)
- depends on OF && HAS_IOMEM
- help
- This enables support for the Quad SPI controller in master mode.
- This driver does not support generic SPI. The implementation only
- supports SPI NOR.
- config SPI_CADENCE_QUADSPI
- tristate "Cadence Quad SPI controller"
- depends on OF && ARM
- help
- Enable support for the Cadence Quad SPI Flash controller.
- Cadence QSPI is a specialized controller for connecting an SPI
- Flash over 1/2/4-bit wide bus. Enable this option if you have a
- device with a Cadence QSPI controller and want to access the
- Flash as an MTD device.
- config SPI_FSL_QUADSPI

- This enables support for the Quad SPI controller in master mode.
- This controller does not support generic SPI. It only supports
- SPI NOR.

- 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.
