Subject: [PATCH] arm64: dts: qcom: Move rmtfs memory region
Date: Mon, 29 Mar 2021 18:46:10 -0700
Message-ID: <20210330014610.1451198-1-sujitka@chromium.org> (raw)

Move rmtfs memory region so that it does not overlap with system
RAM (kernel data) when KAsan is enabled. This puts rmtfs right
after mba_mem which is not supposed to increase beyond 0x94600000
