6config MTD
7	bool "Enable Driver Model for MTD drivers"
8	depends on DM
9	help
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.

25config FLASH_CFI_DRIVER
26	bool "Enable CFI Flash driver"
27	help
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.

54	depends on FLASH_CFI_DRIVER
55	help
56	  This option enables the building of the cfi_mtd driver
57	  in the drivers directory. The driver exports CFI flash
58	  to the MTD layer.
59
60config SYS_FLASH_PROTECTION
61	bool "Use hardware flash protection"
62	depends on FLASH_CFI_DRIVER
63	help
64	  If defined, hardware flash sectors protection is used
65	  instead of U-Boot software protection.
66
67config SYS_FLASH_CFI
68	bool "Define extra elements in CFI for flash geometry"
69	depends on FLASH_CFI_DRIVER
70	help
71	  Define if the flash driver uses extra elements in the
72	  common flash structure for storing flash geometry.
73
74config ALTERA_QSPI
75	bool "Altera Generic Quad SPI Controller"
76	depends on MTD
77	help
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.
