31config FLASH_CFI_DRIVER
32	bool "Enable CFI Flash driver"
33	help
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.

56	  Use buffered writes to flash.
57
58config FLASH_CFI_MTD
59	bool "Enable CFI MTD driver"
60	depends on FLASH_CFI_DRIVER
61	help
62	  This option enables the building of the cfi_mtd driver
63	  in the drivers directory. The driver exports CFI flash
64	  to the MTD layer.
65
66config SYS_FLASH_PROTECTION
67	bool "Use hardware flash protection"
68	depends on FLASH_CFI_DRIVER
69	help
70	  If defined, hardware flash sectors protection is used
71	  instead of U-Boot software protection.
72
73config SYS_FLASH_CFI
74	bool "Define extra elements in CFI for flash geometry"
75	depends on FLASH_CFI_DRIVER
76	help
77	  Define if the flash driver uses extra elements in the
78	  common flash structure for storing flash geometry.
79
80config ALTERA_QSPI
81	bool "Altera Generic Quad SPI Controller"
82	depends on MTD
83	help
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.
