Date: Tue, 23 Jun 2020 21:56:56 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Rob Herring <robh@...nel.org>, James Tai <james.tai@...ltek.com>, Andreas Färber <afaerber@...e.de> Subject: [PATCH 5.7 419/477] arm64: dts: realtek: rtd129x: Carve out boot ROM from memory From: Andreas Färber <afaerber@...e.de> commit 3040e132beda2aee56e6ea9be8db69889bcb2e7a upstream. Update DS418j, MeLE V9, PROBOX2 AVA, Zidoo X9S and DS418 /memory nodes to exclude 0..0x1efff from reg entry and update unit address to match. Add this region to /soc ranges and for now just update the /memreserve/s. Suggested-by: Rob Herring <robh@...nel.org> Fixes: 72a7786c0a0d ("ARM64: dts: Add Realtek RTD1295 and Zidoo X9S") Fixes: d938a964a966 ("arm64: dts: realtek: Add ProBox2 Ava") Fixes: a9ce6f854581 ("arm64: dts: realtek: Add MeLE V9") Fixes: cf976f660ee8 ("arm64: dts: realtek: Add RTD1293 and Synology DS418j") Fixes: 5133636e41a2 ("arm64: dts: realtek: Add RTD1296 and Synology DS418") Cc: James Tai <james.tai@...ltek.com> Signed-off-by: Andreas Färber <afaerber@...e.de> Signed-off-by: Greg Kroah-Hartman <gregkh@...uxfoundation.org> --- arch/arm64/boot/dts/realtek/rtd1293-ds418j.dts | 6 +++--- arch/arm64/boot/dts/realtek/rtd1295-mele-v9.dts | 6 +++--- arch/arm64/boot/dts/realtek/rtd1295-probox2-ava.dts | 6 +++--- arch/arm64/boot/dts/realtek/rtd1295-zidoo-x9s.dts | 4 ++-- arch/arm64/boot/dts/realtek/rtd1296-ds418.dts | 4 ++-- arch/arm64/boot/dts/realtek/rtd129x.dtsi | 9 +++++---- 6 files changed, 18 insertions(+), 17 deletions(-) --- a/arch/arm64/boot/dts/realtek/rtd1293-ds418j.dts +++ b/arch/arm64/boot/dts/realtek/rtd1293-ds418j.dts @@ -1,6 +1,6 @@ // SPDX-License-Identifier: (GPL-2.0-or-later OR BSD-2-Clause) /* - * Copyright (c) 2017 Andreas Färber + * Copyright (c) 2017-2019 Andreas Färber */ /dts-v1/; @@ -11,9 +11,9 @@ compatible = "synology,ds418j", "realtek,rtd1293"; model = "Synology DiskStation DS418j"; - memory@0 { + memory@...00 { device_type = "memory"; - reg = <0x0 0x40000000>; + reg = <0x1f000 0x3ffe1000>; /* boot ROM to 1 GiB */ }; aliases { --- a/arch/arm64/boot/dts/realtek/rtd1295-mele-v9.dts +++ b/arch/arm64/boot/dts/realtek/rtd1295-mele-v9.dts @@ -1,5 +1,5 @@ /* - * Copyright (c) 2017 Andreas Färber + * Copyright (c) 2017-2019 Andreas Färber * * SPDX-License-Identifier: (GPL-2.0+ OR MIT) */ @@ -12,9 +12,9 @@ compatible = "mele,v9", "realtek,rtd1295"; model = "MeLE V9"; - memory@0 { + memory@...00 { device_type = "memory"; - reg = <0x0 0x80000000>; + reg = <0x1f000 0x7ffe1000>; /* boot ROM to 2 GiB */ }; aliases { --- a/arch/arm64/boot/dts/realtek/rtd1295-probox2-ava.dts +++ b/arch/arm64/boot/dts/realtek/rtd1295-probox2-ava.dts @@ -1,5 +1,5 @@ /* - * Copyright (c) 2017 Andreas Färber + * Copyright (c) 2017-2019 Andreas Färber * * SPDX-License-Identifier: (GPL-2.0+ OR MIT) */ @@ -12,9 +12,9 @@ compatible = "probox2,ava", "realtek,rtd1295"; model = "PROBOX2 AVA"; - memory@0 { + memory@...00 { device_type = "memory"; - reg = <0x0 0x80000000>; + reg = <0x1f000 0x7ffe1000>; /* boot ROM to 2 GiB */ }; aliases { --- a/arch/arm64/boot/dts/realtek/rtd1295-zidoo-x9s.dts +++ b/arch/arm64/boot/dts/realtek/rtd1295-zidoo-x9s.dts @@ -11,9 +11,9 @@ compatible = "zidoo,x9s", "realtek,rtd1295"; model = "Zidoo X9S"; - memory@0 { + memory@...00 { device_type = "memory"; - reg = <0x0 0x80000000>; + reg = <0x1f000 0x7ffe1000>; /* boot ROM to 2 GiB */ }; aliases { --- a/arch/arm64/boot/dts/realtek/rtd1296-ds418.dts +++ b/arch/arm64/boot/dts/realtek/rtd1296-ds418.dts @@ -11,9 +11,9 @@ compatible = "synology,ds418", "realtek,rtd1296"; model = "Synology DiskStation DS418"; - memory@0 { + memory@...00 { device_type = "memory"; - reg = <0x0 0x80000000>; + reg = <0x1f000 0x7ffe1000>; /* boot ROM to 2 GiB */ }; aliases { --- a/arch/arm64/boot/dts/realtek/rtd129x.dtsi +++ b/arch/arm64/boot/dts/realtek/rtd129x.dtsi @@ -5,8 +5,8 @@ * Copyright (c) 2016-2019 Andreas Färber */ -/memreserve/ 0x0000000000000000 0x0000000000030000; -/memreserve/ 0x0000000000030000 0x00000000000d0000; +/memreserve/ 0x0000000000000000 0x000000000001f000; +/memreserve/ 0x000000000001f000 0x00000000000e1000; /memreserve/ 0x0000000001b00000 0x00000000004be000; #include <dt-bindings/interrupt-controller/arm-gic.h> @@ -52,8 +52,9 @@ compatible = "simple-bus"; #address-cells = <1>; #size-cells = <1>; - /* Exclude up to 2 GiB of RAM */ - ranges = <0x80000000 0x80000000 0x80000000>; + ranges = <0x00000000 0x00000000 0x0001f000>, /* boot ROM */ + /* Exclude up to 2 GiB of RAM */ + <0x80000000 0x80000000 0x80000000>; reset1: reset-controller@...00000 { compatible = "snps,dw-low-reset";
