The Denali NAND controller IP has some variations in terms of

the bus interface. The DMA setup sequence is completely differenct
|
|

between 32bit / 64bit AXI bus variants.

If your Denali NAND controller is the 64-bit variant, say Y.

Otherwise (32 bit), say N.

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.
