Subject: [PATCH 07/11] fix: ARM64: dts: cp110: Switch to 8-bit ECC NAND setting
Date: Wed, 3 Feb 2021 15:31:34 +0200 [thread overview]
Message-ID: <20210203133138.10754-8-kostap@marvell.com> (raw)
In-Reply-To: <20210203133138.10754-1-kostap@marvell.com>
From: Konstantin Porotchkin <kostap@marvell.com>
All A7K/A8K boards are using NAND chip that supports
8 bit ECC strength. Using lower ECC strength is not recommended
by the flash manufacturer and may cause data corruption.
This patch changes the nand-ecc-strength value from 4 to 8.
