Some variants of the Denali NAND controller need some registers set up based on the device information that has been detected during nand_scan_ident(). CONFIG_SYS_NAND_SELF_INIT has to be defined to insert code between nand_scan_ident() and nand_scan_tail(). It is also helpful to reduce the difference between this driver and its Linux counterpart because this driver was ported from Linux. Moreover, doc/README.nand recommends to use CONFIG_SYS_NAND_SELF_INIT.

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.

This option specifies the number of bytes to skip from the beginning

of OOB area before last ECC sector data starts. This is potentially

used to preserve the bad block marker in the OOB area.
