Subject: [PATCH v13 15/20] mtd: nand: Use the new generic ECC object
Date: Thu, 27 Aug 2020 10:52:03 +0200	[thread overview]
Message-ID: <20200827085208.16276-16-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20200827085208.16276-1-miquel.raynal@bootlin.com>

Embed a generic NAND ECC high-level object in the nand_device
structure to carry all the ECC engine configuration/data.
