10 SPI-NOR, SPI-NAND, OneNAND, etc.
13 bool "Enable Driver Model for MTD drivers"
16 Enable driver model for Memory Technology Devices (MTD), such as
17 flash, RAM and similar chips, often used for solid state file
18 systems on embedded devices.
21 bool "Enable parallel NOR flash support"
23 Enable support for parallel NOR flash.
25 config SYS_MTDPARTS_RUNTIME
26 bool "Allow MTDPARTS to be configured at runtime"
29 This option allows to call the function board_mtdparts_default to
30 dynamically build the variables mtdids and mtdparts at runtime.
32 config FLASH_CFI_DRIVER
33 bool "Enable CFI Flash driver"
35 The Common Flash Interface specification was developed by Intel,
36 AMD and other flash manufactures. It provides a universal method
37 for probing the capabilities of flash devices. If you wish to
38 support any device that is CFI-compliant, you need to enable this
39 option. Visit <http://www.amd.com/products/nvd/overview/cfi.html>
40 for more information on CFI.
43 bool "Enable Driver Model for CFI Flash driver"
45 select FLASH_CFI_DRIVER
47 The Common Flash Interface specification was developed by Intel,
48 AMD and other flash manufactures. It provides a universal method
49 for probing the capabilities of flash devices. If you wish to
50 support any device that is CFI-compliant, you need to enable this
51 option. Visit <http://www.amd.com/products/nvd/overview/cfi.html>
52 for more information on CFI.
54 config SYS_FLASH_USE_BUFFER_WRITE
55 bool "Enable buffered writes to flash"
56 depends on FLASH_CFI_DRIVER
58 Use buffered writes to flash.
61 bool "Enable CFI MTD driver"
62 depends on FLASH_CFI_DRIVER
64 This option enables the building of the cfi_mtd driver
65 in the drivers directory. The driver exports CFI flash
68 config SYS_FLASH_PROTECTION
69 bool "Use hardware flash protection"
70 depends on FLASH_CFI_DRIVER
72 If defined, hardware flash sectors protection is used
73 instead of U-Boot software protection.
76 bool "Define extra elements in CFI for flash geometry"
77 depends on FLASH_CFI_DRIVER
79 Define if the flash driver uses extra elements in the
80 common flash structure for storing flash geometry.
83 bool "Altera Generic Quad SPI Controller"
86 This enables access to Altera EPCQ/EPCS flash chips using the
87 Altera Generic Quad SPI Controller. The controller converts SPI
88 NOR flash to parallel flash interface. Please find details on the
89 "Embedded Peripherals IP User Guide" of Altera.
92 bool "Microchip PIC32 Flash driver"
93 depends on MACH_PIC32 && DM_MTD
95 This enables access to Microchip PIC32 internal non-CFI flash
96 chips through PIC32 Non-Volatile-Memory Controller.
99 bool "Renesas RCar Gen3 RPC HyperFlash driver"
100 depends on RCAR_GEN3 && DM_MTD
102 This enables access to HyperFlash memory through the Renesas
103 RCar Gen3 RPC controller.
106 bool "HyperBus controller driver for AM65x SoC"
109 This is the driver for HyperBus controller on TI's AM65x and
113 bool "STM32 MCU Flash driver"
114 depends on ARCH_STM32
116 This is the driver of embedded flash for some STMicroelectronics
