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

440 hardware engine and use NAND boot mode.
441 Some legacy platforms like OMAP3xx do not have in-built ELM h/w engine,
