mtd: rawnand: Change Kconfig titles and re-order a bit the list 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. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>

depends on JZ4780_NEMC
help
Enables support for NAND Flash connected to the NEMC on JZ4780 SoC
based boards, using the BCH controller for hardware error correction.
mtd: rawnand: ingenic: Separate top-level and SoC specific code 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.

mtd: rawnand: ingenic: Fix ingenic_ecc dependency 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.
