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

435 hardware engine and use NAND boot mode.
436 Some legacy platforms like OMAP3xx do not have in-built ELM h/w engine,
437 so those platforms should use CONFIG_SPL_NAND_SIMPLE for enabling
438 SPL-NAND driver with software ECC correction support.
