Subject: [PATCH 3/6] ARM: dts: omap3-n900: Add secure reserved region to ocmcram node
Date: Mon, 9 May 2016 16:49:23 -0500 [thread overview]
Message-ID: <1462830566-28708-4-git-send-email-d-gerlach@ti.com> (raw)
In-Reply-To: <1462830566-28708-1-git-send-email-d-gerlach@ti.com>
Platforms with secure silicon, like omap3-n900, need to mark off a
section of the ocmcram as reserved because it is used by secure
software.
