Subject: [PATCH v3 04/40] mtd: rawnand: Separate the ECC engine type and the OOB placement
Date: Thu, 19 Sep 2019 21:31:04 +0200
Message-ID: <20190919193141.7865-5-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20190919193141.7865-1-miquel.raynal@bootlin.com>
The use of "OOB_FIRST" or "SYNDROME" placements should not be encoded
in the ECC engine mode (also called type, or provider).
Create a "placement" field in NAND chip and change all occurrences of
the NAND_ECC_HW_SYNDROME and NAND_ECC_HW_OOB_FIRST enumerations to be
just NAND_ECC_HW and possibly a placement entry like
NAND_ECC_SYNDROME_OOB_PLACEMENT or NAND_ECC_OOB_FIRST_PLACEMENT.
