+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.
