Subject: [PATCH v3 2/2] arm64: dts: ti: k3-am64-main: Add ELM (Error Location Module) node
Date: Fri, 4 Feb 2022 13:15:33 +0200 [thread overview]
Message-ID: <20220204111533.10787-3-rogerq@kernel.org> (raw)
In-Reply-To: <20220204111533.10787-1-rogerq@kernel.org>
The ELM module is used for GPMC NAND accesses for detecting
and correcting errors during reads due to NAND bitflips errors.
4-, 8-, and 16-bit error-correction levels are supported using
the BCH (Bose-ChaudhurI-Hocquenghem) algorithm.
