Subject: [PATCH 2/3] ARM: dts: da850-lcdk: Add and enable CMA reserved pool for DSP
Date: Mon, 18 Sep 2017 19:28:32 -0500	[thread overview]
Message-ID: <20170919002833.5677-3-s-anna@ti.com> (raw)
In-Reply-To: <20170919002833.5677-1-s-anna@ti.com>

A CMA reserved memory node of 16 MB has been added and assigned to
the DSP remoteproc device on the OMAP-L138 LCDK board. The CMA starting
address matches the values used within the TI IPC 3.x software. Both
the CMA node and the corresponding rproc node are also marked okay
to enable the DSP on the OMAP-L138 LCDK board.
