Masahiro Yamada 65e4145a20 mtd: denali: use CONFIG_SYS_NAND_SELF_INIT
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.

config SYS_NAND_SELF_INIT

This option, if enabled, provides more flexible and linux-like
NAND initialization process.

Enable support for the Denali NAND controller.

depends on NAND_DENALI
help
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.
config NAND_DENALI_SPARE_AREA_SKIP_BYTES
int "Number of bytes skipped in OOB area"
depends on NAND_DENALI
range 0 63
help
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.

bool "Support Denali NAND controller for SPL"
help
This is a small implementation of the Denali NAND controller
for use on SPL.
