Subject: [PATCH v4 3/8] ARM: aurora-l2: add defines for parity and ECC registers
Date: Fri, 12 Jan 2018 14:27:50 +1300 [thread overview]
Message-ID: <20180112012755.20495-4-chris.packham@alliedtelesis.co.nz> (raw)
In-Reply-To: <20180112012755.20495-1-chris.packham@alliedtelesis.co.nz>
From: Jan Luebbe <jlu@pengutronix.de>
These defines will be used by subsequent patches to add support for the
parity check and error correction functionality in the Aurora L2 cache
controller.
