Subject: [PATCH v6 9/9] EDAC: armada_xp: Add support for more SoCs
Date: Fri,  9 Nov 2018 20:03:49 +1300	[thread overview]
Message-ID: <20181109070349.20464-10-chris.packham@alliedtelesis.co.nz> (raw)
In-Reply-To: <20181109070349.20464-1-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.
