32config FLASH_CFI_DRIVER
33	bool "Enable CFI Flash driver"
34	help
35	  The Common Flash Interface specification was developed by Intel,
36	  AMD and other flash manufactures. It provides a universal method
37	  for probing the capabilities of flash devices. If you wish to
38	  support any device that is CFI-compliant, you need to enable this
39	  option. Visit <http://www.amd.com/products/nvd/overview/cfi.html>
40	  for more information on CFI.

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