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

|

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
