1menu "MTD Support" 2 3config MTD 4 bool "Enable Driver Model for MTD drivers" 5 depends on DM 6 help 7 Enable driver model for Memory Technology Devices (MTD), such as 8 flash, RAM and similar chips, often used for solid state file 9 systems on embedded devices. 10 11config MTD_NOR_FLASH 12 bool "Enable parallel NOR flash support" 13 help 14 Enable support for parallel NOR flash. 15 16config MTD_DEVICE 17 bool "Enable MTD Device for NAND and ONENAND devices" 18 help 19 Adds the MTD device infrastructure from the Linux kernel. 20 Needed for mtdparts command support. 21 22config MTD_PARTITIONS 23 bool "Add MTD Partioning infrastructure" 24 help 25 Adds the MTD partitioning infrastructure from the Linux 26 kernel. Needed for UBI support. 27 28config CFI_FLASH 29 bool "Enable Driver Model for CFI Flash driver" 30 depends on MTD 31 help 32 The Common Flash Interface specification was developed by Intel, 33 AMD and other flash manufactures. It provides a universal method 34 for probing the capabilities of flash devices. If you wish to 35 support any device that is CFI-compliant, you need to enable this 36 option. Visit <http://www.amd.com/products/nvd/overview/cfi.html> 37 for more information on CFI. 38 39config ALTERA_QSPI 40 bool "Altera Generic Quad SPI Controller" 41 depends on MTD 42 help 43 This enables access to Altera EPCQ/EPCS flash chips using the 44 Altera Generic Quad SPI Controller. The controller converts SPI 45 NOR flash to parallel flash interface. Please find details on the 46 "Embedded Peripherals IP User Guide" of Altera. 47 48config FLASH_PIC32 49 bool "Microchip PIC32 Flash driver" 50 depends on MACH_PIC32 && MTD 51 help 52 This enables access to Microchip PIC32 internal non-CFI flash 53 chips through PIC32 Non-Volatile-Memory Controller. 54 55config RENESAS_RPC_HF 56 bool "Renesas RCar Gen3 RPC Hyperflash driver" 57 depends on RCAR_GEN3 && MTD 58 help 59 This enables access to Hyperflash memory through the Renesas 60 RCar Gen3 RPC controller. 61 62endmenu 63 64source "drivers/mtd/nand/Kconfig" 65 66source "drivers/mtd/spi/Kconfig" 67 68source "drivers/mtd/ubi/Kconfig" 69
