2 tristate "SPI-NOR device support"
5 This is the framework for the SPI NOR which can be used by the SPI
6 device drivers and the SPI-NOR device driver.
11 tristate "Mediatek MT81xx SPI NOR flash controller"
14 This enables access to SPI NOR flash, using MT81xx SPI NOR flash
15 controller. This controller does not support generic SPI BUS, it only
16 supports SPI NOR Flash.
18 config MTD_SPI_NOR_USE_4K_SECTORS
19 bool "Use small 4096 B erase sectors"
22 Many flash memories support erasing small (4096 B) sectors. Depending
23 on the usage this feature may provide performance gain in comparison
24 to erasing whole blocks (32/64 KiB).
25 Changing a small part of the flash's contents is usually faster with
26 small sectors. On the other hand erasing should be faster when using
27 64 KiB block instead of 16 × 4 KiB sectors.
29 Please note that some tools/drivers/filesystems may not work with
30 4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum).
33 tristate "Aspeed flash controllers in SPI mode"
34 depends on ARCH_ASPEED || COMPILE_TEST
35 depends on HAS_IOMEM && OF
37 This enables support for the Firmware Memory controller (FMC)
38 in the Aspeed AST2500/AST2400 SoCs when attached to SPI NOR chips,
39 and support for the SPI flash memory controller (SPI) for
40 the host firmware. The implementation only supports SPI NOR.
42 config SPI_CADENCE_QUADSPI
43 tristate "Cadence Quad SPI controller"
44 depends on OF && (ARM || ARM64 || COMPILE_TEST)
46 Enable support for the Cadence Quad SPI Flash controller.
48 Cadence QSPI is a specialized controller for connecting an SPI
49 Flash over 1/2/4-bit wide bus. Enable this option if you have a
50 device with a Cadence QSPI controller and want to access the
51 Flash as an MTD device.
53 config SPI_FSL_QUADSPI
54 tristate "Freescale Quad SPI controller"
55 depends on ARCH_MXC || SOC_LS1021A || ARCH_LAYERSCAPE || COMPILE_TEST
58 This enables support for the Quad SPI controller in master mode.
59 This controller does not support generic SPI. It only supports
63 tristate "Hisilicon SPI-NOR Flash Controller(SFC)"
64 depends on ARCH_HISI || COMPILE_TEST
67 This enables support for hisilicon SPI-NOR flash controller.
70 tristate "NXP SPI Flash Interface (SPIFI)"
71 depends on OF && (ARCH_LPC18XX || COMPILE_TEST)
74 Enable support for the NXP LPC SPI Flash Interface controller.
76 SPIFI is a specialized controller for connecting serial SPI
77 Flash. Enable this option if you have a device with a SPIFI
78 controller and want to access the Flash as a mtd device.
83 config SPI_INTEL_SPI_PCI
84 tristate "Intel PCH/PCU SPI flash PCI driver (DANGEROUS)"
88 This enables PCI support for the Intel PCH/PCU SPI controller in
89 master mode. This controller is present in modern Intel hardware
90 and is used to hold BIOS and other persistent settings. Using
91 this driver it is possible to upgrade BIOS directly from Linux.
93 Say N here unless you know what you are doing. Overwriting the
94 SPI flash may render the system unbootable.
96 To compile this driver as a module, choose M here: the module
97 will be called intel-spi-pci.
99 config SPI_INTEL_SPI_PLATFORM
100 tristate "Intel PCH/PCU SPI flash platform driver (DANGEROUS)"
104 This enables platform support for the Intel PCH/PCU SPI
105 controller in master mode. This controller is present in modern
106 Intel hardware and is used to hold BIOS and other persistent
107 settings. Using this driver it is possible to upgrade BIOS
110 Say N here unless you know what you are doing. Overwriting the
111 SPI flash may render the system unbootable.
113 To compile this driver as a module, choose M here: the module
114 will be called intel-spi-platform.
116 config SPI_STM32_QUADSPI
117 tristate "STM32 Quad SPI controller"
118 depends on ARCH_STM32 || COMPILE_TEST
120 This enables support for the STM32 Quad SPI controller.
121 We only connect the NOR to this controller.
