- 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.

- 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 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.
