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.
25 config FLASH_CFI_DRIVER
26 bool "Enable CFI Flash driver"
28 The Common Flash Interface specification was developed by Intel,
29 AMD and other flash manufactures. It provides a universal method
30 for probing the capabilities of flash devices. If you wish to
31 support any device that is CFI-compliant, you need to enable this
32 option. Visit <http://www.amd.com/products/nvd/overview/cfi.html>
33 for more information on CFI.
36 bool "Enable Driver Model for CFI Flash driver"
39 The Common Flash Interface specification was developed by Intel,
40 AMD and other flash manufactures. It provides a universal method
41 for probing the capabilities of flash devices. If you wish to
42 support any device that is CFI-compliant, you need to enable this
43 option. Visit <http://www.amd.com/products/nvd/overview/cfi.html>
44 for more information on CFI.
46 config SYS_FLASH_USE_BUFFER_WRITE
47 bool "Enable buffered writes to flash"
48 depends on FLASH_CFI_DRIVER
50 Use buffered writes to flash.
53 bool "Enable CFI MTD driver"
54 depends on FLASH_CFI_DRIVER
56 This option enables the building of the cfi_mtd driver
57 in the drivers directory. The driver exports CFI flash
60 config SYS_FLASH_PROTECTION
61 bool "Use hardware flash protection"
62 depends on FLASH_CFI_DRIVER
64 If defined, hardware flash sectors protection is used
65 instead of U-Boot software protection.
68 bool "Define extra elements in CFI for flash geometry"
69 depends on FLASH_CFI_DRIVER
71 Define if the flash driver uses extra elements in the
72 common flash structure for storing flash geometry.
75 bool "Altera Generic Quad SPI Controller"
78 This enables access to Altera EPCQ/EPCS flash chips using the
79 Altera Generic Quad SPI Controller. The controller converts SPI
80 NOR flash to parallel flash interface. Please find details on the
81 "Embedded Peripherals IP User Guide" of Altera.
84 bool "Microchip PIC32 Flash driver"
85 depends on MACH_PIC32 && DM_MTD
87 This enables access to Microchip PIC32 internal non-CFI flash
88 chips through PIC32 Non-Volatile-Memory Controller.
91 bool "Renesas RCar Gen3 RPC Hyperflash driver"
92 depends on RCAR_GEN3 && DM_MTD
94 This enables access to Hyperflash memory through the Renesas
95 RCar Gen3 RPC controller.
98 bool "HyperBus controller driver for AM65x SoC"
101 This is the driver for HyperBus controller on TI's AM65x and
