From mboxrd@z Thu Jan 1 00:00:00 1970 From: s-anna@ti.com (Suman Anna) Date: Thu, 1 Sep 2016 17:58:44 -0500 Subject: [PATCH 3/5] ARM: dts: keystone-k2e: Add MSM RAM node In-Reply-To: <20160901225846.31058-1-s-anna@ti.com> References: <20160901225846.31058-1-s-anna@ti.com> Message-ID: <20160901225846.31058-4-s-anna@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Add the RAM managed by the Multicire Shared Memory Controller (MSMC) as a mmio-sram node. The Keystone 2 Edison SoC has 2 MB of such memory. Any specific MSM memory range needed by a software module ought to be reserved using an appropriate child node.
