10 NAND initialization process.

17 Enable support for the Denali NAND controller.
19 config SYS_NAND_DENALI_64BIT
20 bool "Use 64-bit variant of Denali NAND controller"
21 depends on NAND_DENALI
23 The Denali NAND controller IP has some variations in terms of
24 the bus interface. The DMA setup sequence is completely differenct
25 between 32bit / 64bit AXI bus variants.
27 If your Denali NAND controller is the 64-bit variant, say Y.
28 Otherwise (32 bit), say N.
30 config NAND_DENALI_SPARE_AREA_SKIP_BYTES
31 int "Number of bytes skipped in OOB area"
32 depends on NAND_DENALI
35 This option specifies the number of bytes to skip from the beginning
36 of OOB area before last ECC sector data starts. This is potentially
37 used to preserve the bad block marker in the OOB area.
40 bool "Support for Freescale NFC for VF610"
41 select SYS_NAND_SELF_INIT
44 Enables support for NAND Flash Controller on some Freescale
45 processors like the VF610, MCF54418 or Kinetis K70.

74 depends on MACH_SUN4I || MACH_SUN5I || MACH_SUN7I
75 select SYS_NAND_SELF_INIT

101 bool "Configure Arasan Nand"
104 This enables Nand driver support for Arasan nand flash
105 controller. This uses the hardware ECC for read and
109 bool "MXS NAND support"
110 depends on MX6 || MX7
113 This enables NAND driver for the NAND flash controller on the
117 bool "Support for Zynq Nand controller"
118 select SYS_NAND_SELF_INIT
121 This enables Nand driver support for Nand flash controller
124 comment "Generic NAND options"
126 # Enhance depends when converting drivers to Kconfig which use this config
127 # option (mxc_nand, ndfc, omap_gpmc).
128 config SYS_NAND_BUSWIDTH_16BIT
129 bool "Use 16-bit NAND interface"
130 depends on NAND_VF610_NFC
132 Indicates that NAND device has 16-bit wide data-bus. In absence of this
133 config, bus-width of NAND device is assumed to be either 8-bit and later
134 determined by reading ONFI params.
135 Above config is useful when NAND device's bus-width information cannot
136 be determined from on-chip ONFI params, like in following scenarios:
137 - SPL boot does not support reading of ONFI parameters. This is done to
138 keep SPL code foot-print small.
139 - In current U-Boot flow using nand_init(), driver initialization
140 happens in board_nand_init() which is called before any device probe
141 (nand_scan_ident + nand_scan_tail), thus device's ONFI parameters are
142 not available while configuring controller. So a static CONFIG_NAND_xx
143 is needed to know the device's bus-width in advance.
147 config SYS_NAND_U_BOOT_LOCATIONS
148 bool "Define U-boot binaries locations in NAND"
150 Enable CONFIG_SYS_NAND_U_BOOT_OFFS though Kconfig.
