The Amlogic Meson GXBB/GXL/GXM secure monitor uses part of the memory space, this patch adds this reserved zone and redefines the usable memory range. Signed-off-by: Neil Armstrong <narmstrong@xxxxxxxxxxxx> --- Changes since v1 at [1] : - Renamed reg into linux,usable-memory to ovveride u-boot memory - only kept secmon memory zone [1] http://lkml.kernel.org/r/20161212101801.28491-1-narmstrong@xxxxxxxxxxxx arch/arm64/boot/dts/amlogic/meson-gx-p23x-q20x.dtsi | 2 +- arch/arm64/boot/dts/amlogic/meson-gx.dtsi | 12 ++++++++++++ arch/arm64/boot/dts/amlogic/meson-gxbb-nexbox-a95x.dts | 2 +- arch/arm64/boot/dts/amlogic/meson-gxbb-odroidc2.dts | 2 +- arch/arm64/boot/dts/amlogic/meson-gxbb-p20x.dtsi | 2 +- arch/arm64/boot/dts/amlogic/meson-gxbb-vega-s95-meta.dts | 2 +- arch/arm64/boot/dts/amlogic/meson-gxbb-vega-s95-pro.dts | 2 +- arch/arm64/boot/dts/amlogic/meson-gxbb-vega-s95-telos.dts | 2 +- arch/arm64/boot/dts/amlogic/meson-gxl-nexbox-a95x.dts | 2 +- arch/arm64/boot/dts/amlogic/meson-gxl-s905x-p212.dts | 2 +- arch/arm64/boot/dts/amlogic/meson-gxm-nexbox-a1.dts | 2 +- 11 files changed, 22 insertions(+), 10 deletions(-) diff --git a/arch/arm64/boot/dts/amlogic/meson-gx-p23x-q20x.dtsi b/arch/arm64/boot/dts/amlogic/meson-gx-p23x-q20x.dtsi index 7a078be..ca3c7fa 100644 --- a/arch/arm64/boot/dts/amlogic/meson-gx-p23x-q20x.dtsi +++ b/arch/arm64/boot/dts/amlogic/meson-gx-p23x-q20x.dtsi @@ -56,7 +56,7 @@ memory@0 { device_type = "memory";
