This driver has no arch-specific instructions but is only ever useful
on MIPS; so disable this driver if we're not compiling for MIPS, unless
the driver is compile-tested.

It has been replaced with the newer Ingenic NAND driver.

If MTD_NAND_JZ4780 is y and MTD_NAND_JZ4780_BCH is m,
which select CONFIG_MTD_NAND_INGENIC_ECC to m, building fails:
drivers/mtd/nand/raw/ingenic/ingenic_nand.o: In function `ingenic_nand_remove':
ingenic_nand.c:(.text+0x177): undefined reference to `ingenic_ecc_release'
drivers/mtd/nand/raw/ingenic/ingenic_nand.o: In function `ingenic_nand_ecc_correct':
ingenic_nand.c:(.text+0x2ee): undefined reference to `ingenic_ecc_correct'
To fix that, the ingenic_nand and ingenic_ecc modules have been fused
into one single module.
- The ingenic_ecc.c code is now compiled in only if
$(CONFIG_MTD_NAND_INGENIC_ECC) is set. This is now a boolean instead
of tristate.
- To avoid changing the module name, the ingenic_nand.c file is moved to
ingenic_nand_drv.c. Then the module name is still ingenic_nand.
- Since ingenic_ecc.c is no more a module, the module-specific macros
have been dropped, and the functions are no more exported for use by
the ingenic_nand driver.

Add SPDX license identifiers to all Make/Kconfig files which:
- Have no license information of any form
These files fall under the project license, GPL v2 only. The resulting SPDX

This list is a mess, while some items should probably not be in the
raw/ sub-directory, others are definitely at the right place but not
with the right description. Write uniform titles and group IPs by
vendor.
NAND controllers will appear under the list named "Raw/parallel NAND
flash controllers" while the other drivers will appear under
"Misc". Software ECC engines will later be moved out of the raw/
directory.

The boot ROM of the JZ4725B SoC expects a specific OOB layout on the
NAND, so we use it unconditionally in the ingenic-nand driver.
Also add the jz4725b-bch driver to support the JZ4725B-specific BCH
hardware.

Add support for probing the ingenic-nand driver on the JZ4740 SoC from
Ingenic, and the jz4740-ecc driver to support the JZ4740-specific
ECC hardware.

The ingenic-nand driver uses an API provided by the jz4780-bch driver.
This makes it difficult to support other SoCs in the jz4780-bch driver.
To work around this, we separate the API functions from the SoC-specific
code, so that these API functions are SoC-agnostic.

Before adding support for more SoCs and seeing the number of files for
these drivers grow, we move them to their own subfolder to keep it tidy.
