config SYS_NAND_SELF_INIT
bool
help
This option, if enabled, provides more flexible and linux-like
NAND initialization process.
config NAND_DENALI

help
Enable support for the Denali NAND controller.
config SYS_NAND_DENALI_64BIT
bool "Use 64-bit variant of Denali NAND controller"
depends on NAND_DENALI
help
The Denali NAND controller IP has some variations in terms of
the bus interface. The DMA setup sequence is completely differenct
between 32bit / 64bit AXI bus variants.
If your Denali NAND controller is the 64-bit variant, say Y.
Otherwise (32 bit), say N.
config NAND_DENALI_SPARE_AREA_SKIP_BYTES
int "Number of bytes skipped in OOB area"
depends on NAND_DENALI
range 0 63
help
This option specifies the number of bytes to skip from the beginning
of OOB area before last ECC sector data starts. This is potentially
used to preserve the bad block marker in the OOB area.
config NAND_VF610_NFC
bool "Support for Freescale NFC for VF610/MPC5125"
select SYS_NAND_SELF_INIT
help
Enables support for NAND Flash Controller on some Freescale
processors like the VF610, MPC5125, MCF54418 or Kinetis K70.
The driver supports a maximum 2k page size. The driver
currently does not support hardware ECC.

This enables the driver for the NAND flash device found on
PXA3xx processors (NFCv1) and also on Armada 370/XP (NFCv2).

---help---
Enable support for NAND. This option enables the standard and
SPL drivers.
The SPL driver only supports reading from the NAND using DMA
transfers.
config NAND_ARASAN
bool "Configure Arasan Nand"
help
This enables Nand driver support for Arasan nand flash
controller. This uses the hardware ECC for read and
write operations.

help
This enables NAND driver for the NAND flash controller on the
MXS processors.

the configure of page size and ecc type lie on switch on the board.
so the page size and ecc type is controlled by Hardware see demo
board of SOC.

auto-sensed the page size and ecc type value. driver will try each of
page size and ecc type one by one till flash can be read and wrote
accurately. so the page size and ecc type is match adaptively without
switch on the board

config SYS_NAND_BUSWIDTH_16BIT
bool "Use 16-bit NAND interface"
depends on NAND_VF610_NFC
help
Indicates that NAND device has 16-bit wide data-bus. In absence of this
config, bus-width of NAND device is assumed to be either 8-bit and later
determined by reading ONFI params.
Above config is useful when NAND device's bus-width information cannot
be determined from on-chip ONFI params, like in following scenarios:
- SPL boot does not support reading of ONFI parameters. This is done to
keep SPL code foot-print small.
- In current U-Boot flow using nand_init(), driver initialization
happens in board_nand_init() which is called before any device probe
(nand_scan_ident + nand_scan_tail), thus device's ONFI parameters are
not available while configuring controller. So a static CONFIG_NAND_xx
is needed to know the device's bus-width in advance.
