Subject: [U-Boot] [PATCH v6 12/27] mtd: nand: Pass mode information to nand_page_io_req
Date: Wed,  1 Aug 2018 10:18:33 +0200	[thread overview]
Message-ID: <20180801081848.19398-13-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20180801081848.19398-1-miquel.raynal@bootlin.com>

From: Boris Brezillon <boris.brezillon@bootlin.com>

The NAND sub-layers are likely to need the MTD_OPS_XXX mode information
in order to decide if they should enable/disable ECC or how they should
place the OOB bytes in the provided OOB buffer.

Add a field to nand_page_io_req to pass this information.
