Hello, This patch series is a proposal to add per partition ECC config.
It defines a new partition type called nand_part which stores a pointer to a nand_ecc_ctrl struct. This specific nand_ecc_ctrl struct is used in place of the base NAND chip nand_ecc_ctrl struct when accessing NAND chip from nand_part MTD device. If the partition does not define any ECC config, the NAND chip ECC config is used instead. This patch series also provides an helper function to parse DT defined NAND partitions (ofnandpart_parse). If you want to test it you'll have to replace calls to mtd_device_parse_register with ofnandpart_parse within your NAND controller driver and implement a driver specific parser function that will provide the ECC config (see ofnandpart_data struct). The 4th patch of this series is here as an example on how to move from MTD partitions to NAND partitions.
