Subject: [PATCH v3 2/9] dt-bindings: mtd: ingenic: Change 'BCH' to 'ECC' in documentation
Date: Mon, 4 Feb 2019 16:04:19 -0300 [thread overview]
Message-ID: <20190204190426.11618-2-paul@crapouillou.net> (raw)
In-Reply-To: <20190204190426.11618-1-paul@crapouillou.net>
The JZ4740 ECC hardware is not BCH but Reed-Solomon, so it makes more
sense to use the more generic ECC term.
Signed-off-by: Paul Cercueil <paul@crapouillou.net>
