Subject: [PATCH v5 1/6] mtd: spinand: micron: Generalize the OOB layout structure and function names
Date: Fri, 28 Feb 2020 16:03:06 +0100	[thread overview]
Message-ID: <20200228150311.12184-2-sshivamurthy@micron.com> (raw)
In-Reply-To: <20200228150311.12184-1-sshivamurthy@micron.com>

From: Shivamurthy Shastri <sshivamurthy@micron.com>

In order to add new Micron SPI NAND devices, we generalized the OOB
layout structure and function names.
