Subject: [PATCH v9 8/8] EDAC: armada_xp: Add support for more SoCs
Date: Fri, 12 Jul 2019 15:49:04 +1200
Message-ID: <20190712034904.5747-9-chris.packham@alliedtelesis.co.nz> (raw)
In-Reply-To: <20190712034904.5747-1-chris.packham@alliedtelesis.co.nz>

The Armada 38x and other integrated SoCs use a reduced pin count so the
width of the SDRAM interface is smaller than the Armada XP SoCs. This
means that the definition of "full" and "half" width is reduced from
64/32 to 32/16.
