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_MT81xx_NOR
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_FSL_QUADSPI
tristate "Freescale Quad SPI controller"
depends on ARCH_MXC || SOC_LS1021A || ARCH_LAYERSCAPE || 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_HISI_SFC
tristate "Hisilicon SPI-NOR Flash Controller(SFC)"
depends on ARCH_HISI || COMPILE_TEST
depends on HAS_IOMEM && HAS_DMA
help
This enables support for hisilicon SPI-NOR flash controller.
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.
