Hello,
This is the MTD PR for 6.18.
Thanks,
Miquèl

Merge tag 'nand/for-6.18' into mtd/next (2025-10-03 17:23:18 +0200)
----------------------------------------------------------------
MTD core:
- Bad blocks increment is skipped if the block is already known
bad (improves user statistics relevance).
- Expose the OOB layout via debugfs.
* Raw NAND:
- Add support for Loongson-2K1000 and Loongson-2K0500 NAND controllers,
including extra features, such as chip select and 6-byte NAND ID
reading support.
- Drop the s3c2410 driver.
* SPI NAND:
- Important SPI NAND continuous read improvements and fixes.
- Add support for FudanMicro FM25S01A.
- Add support for continuous reads in Gigadevice vendor driver.
* ECC:
- Add support for the Realtek ECC engine.
* SPI NOR:
- Some flashes can't perform reads or writes with start or end being an
odd number in Octal DTR mode. File systems like UBIFS can request such
reads or writes, causing the transaction to error out. Pad the read or
write transactions with extra bytes to avoid this problem.
This PR comes with the usual amount of various miscellaneous fixes.
