This is used by SoC platforms which do not have built-in ELM
hardware engine required for BCH ECC correction.
+ CONFIG_SYS_NAND_BUSWIDTH_16BIT
+ 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.
+ Some drivers using above config are:
+ drivers/mtd/nand/mxc_nand.c
+ drivers/mtd/nand/ndfc.c
+ drivers/mtd/nand/omap_gpmc.c
