Subject: [PATCH 4/5] ARM: dts: keystone-k2g: Add MSM RAM node
Date: Thu, 1 Sep 2016 17:58:45 -0500 [thread overview]
Message-ID: <20160901225846.31058-5-s-anna@ti.com> (raw)
In-Reply-To: <20160901225846.31058-1-s-anna@ti.com>
Add the RAM managed by the Multicore Shared Memory Controller (MSMC)
as a mmio-sram node. The Keystone 2 K2G SoC has 1 MB of such memory.
Any specific MSM memory range needed by a software module ought to
be reserved using an appropriate child node.
