Subject: [PATCH 2/2] arm64: dts: msm8996: Add rmtfs sharedmem node
Date: Mon, 12 Feb 2018 17:37:24 -0800 [thread overview]
Message-ID: <20180213013724.3177-2-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <20180213013724.3177-1-bjorn.andersson@linaro.org>
A 2MB shared memory region is used on MSM8996 for exchanging sector data
in rmtfs. Add this chunk of reserved memory now that we have the
rmtfs-mem compatible to describe it and its memory protection
properties.
