7 bool "Enable Driver Model for MTD drivers"
10 Enable driver model for Memory Technology Devices (MTD), such as
11 flash, RAM and similar chips, often used for solid state file
12 systems on embedded devices.
15 bool "Enable parallel NOR flash support"
17 Enable support for parallel NOR flash.
20 bool "Enable MTD Device for NAND and ONENAND devices"
22 Adds the MTD device infrastructure from the Linux kernel.
23 Needed for mtdparts command support.
26 bool "Add MTD Partioning infrastructure"
28 Adds the MTD partitioning infrastructure from the Linux
29 kernel. Needed for UBI support.
31 config FLASH_CFI_DRIVER
32 bool "Enable CFI Flash driver"
34 The Common Flash Interface specification was developed by Intel,
35 AMD and other flash manufactures. It provides a universal method
36 for probing the capabilities of flash devices. If you wish to
37 support any device that is CFI-compliant, you need to enable this
38 option. Visit <http://www.amd.com/products/nvd/overview/cfi.html>
39 for more information on CFI.
42 bool "Enable Driver Model for CFI Flash driver"
45 The Common Flash Interface specification was developed by Intel,
46 AMD and other flash manufactures. It provides a universal method
47 for probing the capabilities of flash devices. If you wish to
48 support any device that is CFI-compliant, you need to enable this
49 option. Visit <http://www.amd.com/products/nvd/overview/cfi.html>
50 for more information on CFI.
52 config SYS_FLASH_USE_BUFFER_WRITE
53 bool "Enable buffered writes to flash"
54 depends on FLASH_CFI_DRIVER
56 Use buffered writes to flash.
59 bool "Enable CFI MTD driver"
60 depends on FLASH_CFI_DRIVER
62 This option enables the building of the cfi_mtd driver
63 in the drivers directory. The driver exports CFI flash
66 config SYS_FLASH_PROTECTION
67 bool "Use hardware flash protection"
68 depends on FLASH_CFI_DRIVER
70 If defined, hardware flash sectors protection is used
71 instead of U-Boot software protection.
74 bool "Define extra elements in CFI for flash geometry"
75 depends on FLASH_CFI_DRIVER
77 Define if the flash driver uses extra elements in the
78 common flash structure for storing flash geometry.
81 bool "Altera Generic Quad SPI Controller"
84 This enables access to Altera EPCQ/EPCS flash chips using the
85 Altera Generic Quad SPI Controller. The controller converts SPI
86 NOR flash to parallel flash interface. Please find details on the
87 "Embedded Peripherals IP User Guide" of Altera.
90 bool "Microchip PIC32 Flash driver"
91 depends on MACH_PIC32 && MTD
93 This enables access to Microchip PIC32 internal non-CFI flash
94 chips through PIC32 Non-Volatile-Memory Controller.
97 bool "Renesas RCar Gen3 RPC Hyperflash driver"
98 depends on RCAR_GEN3 && MTD
100 This enables access to Hyperflash memory through the Renesas
101 RCar Gen3 RPC controller.
