3 config SYS_NAND_SELF_INIT
6 This option, if enabled, provides more flexible and linux-like
7 NAND initialization process.
10 bool "Support Denali NAND controller"
11 select SYS_NAND_SELF_INIT
14 Enable support for the Denali NAND controller.
16 config SYS_NAND_DENALI_64BIT
17 bool "Use 64-bit variant of Denali NAND controller"
18 depends on NAND_DENALI
20 The Denali NAND controller IP has some variations in terms of
21 the bus interface. The DMA setup sequence is completely differenct
22 between 32bit / 64bit AXI bus variants.
24 If your Denali NAND controller is the 64-bit variant, say Y.
25 Otherwise (32 bit), say N.
27 config NAND_DENALI_SPARE_AREA_SKIP_BYTES
28 int "Number of bytes skipped in OOB area"
29 depends on NAND_DENALI
32 This option specifies the number of bytes to skip from the beginning
33 of OOB area before last ECC sector data starts. This is potentially
34 used to preserve the bad block marker in the OOB area.
37 bool "Support for Freescale NFC for VF610"
38 select SYS_NAND_SELF_INIT
41 Enables support for NAND Flash Controller on some Freescale
42 processors like the VF610, MCF54418 or Kinetis K70.
43 The driver supports a maximum 2k page size. The driver
44 currently does not support hardware ECC.
47 prompt "Hardware ECC strength"
48 depends on NAND_VF610_NFC
49 default SYS_NAND_VF610_NFC_45_ECC_BYTES
51 Select the ECC strength used in the hardware BCH ECC block.

57 bool "32-error correction (60 ECC bytes)"
62 bool "Support for NAND on PXA3xx and Armada 370/XP/38x"
63 select SYS_NAND_SELF_INIT
66 This enables the driver for the NAND flash device found on
67 PXA3xx processors (NFCv1) and also on Armada 370/XP (NFCv2).
70 bool "Support for NAND on Allwinner SoCs"
71 depends on MACH_SUN4I || MACH_SUN5I || MACH_SUN7I
72 select SYS_NAND_SELF_INIT
73 select SYS_NAND_U_BOOT_LOCATIONS
76 Enable support for NAND. This option enables the standard and
78 The SPL driver only supports reading from the NAND using DMA

92 int "Allwinner NAND SPL Usable Page Size"
98 bool "Configure Arasan Nand"
101 This enables Nand driver support for Arasan nand flash
102 controller. This uses the hardware ECC for read and
106 bool "MXS NAND support"
107 depends on MX6 || MX7
110 This enables NAND driver for the NAND flash controller on the

121 comment "Generic NAND options"
123 # Enhance depends when converting drivers to Kconfig which use this config
124 # option (mxc_nand, ndfc, omap_gpmc).
125 config SYS_NAND_BUSWIDTH_16BIT
126 bool "Use 16-bit NAND interface"
127 depends on NAND_VF610_NFC
129 Indicates that NAND device has 16-bit wide data-bus. In absence of this
130 config, bus-width of NAND device is assumed to be either 8-bit and later
131 determined by reading ONFI params.
132 Above config is useful when NAND device's bus-width information cannot
133 be determined from on-chip ONFI params, like in following scenarios:
134 - SPL boot does not support reading of ONFI parameters. This is done to
135 keep SPL code foot-print small.
136 - In current U-Boot flow using nand_init(), driver initialization
137 happens in board_nand_init() which is called before any device probe
138 (nand_scan_ident + nand_scan_tail), thus device's ONFI parameters are
139 not available while configuring controller. So a static CONFIG_NAND_xx
140 is needed to know the device's bus-width in advance.
144 config SYS_NAND_U_BOOT_LOCATIONS
145 bool "Define U-boot binaries locations in NAND"
147 Enable CONFIG_SYS_NAND_U_BOOT_OFFS though Kconfig.
148 This option should not be enabled when compiling U-boot for boards
149 defining CONFIG_SYS_NAND_U_BOOT_OFFS in their include/configs/<board>.h

161 hex "Location in NAND to read U-Boot from"
162 default SYS_NAND_U_BOOT_OFFS

166 should be loaded from.
