From mboxrd@z Thu Jan 1 00:00:00 1970 From: geert+renesas@glider.be (Geert Uytterhoeven) Date: Thu, 15 Dec 2016 16:31:29 +0100 Subject: [PATCH resend] arm64: dts: r8a7796: salvator-x: Update memory node to 4 GiB map Message-ID: <1481815889-15583-1-git-send-email-geert+renesas@glider.be> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Takeshi Kihara This patch updates memory region: - After changes, the new map of the Salvator-X board on R8A7796 SoC Bank0: 2GiB RAM : 0x000048000000 -> 0x000bfffffff Bank1: 2GiB RAM : 0x000600000000 -> 0x0067fffffff - Before changes, the old map looked like this: Bank0: 2GiB RAM : 0x000048000000 -> 0x000bfffffff Signed-off-by: Takeshi Kihara [geert: Correct size of old map] Signed-off-by: Geert Uytterhoeven --- Simon, please apply! U-Boot already adds the second memory region to the "reg" property of the first memory node in DT, so this patch is actually a no-op. IMHO it doesn't make much sense to keep on pretending we don't have enabled memory outside the 32-bit address space. --- arch/arm64/boot/dts/renesas/r8a7796-salvator-x.dts | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/arch/arm64/boot/dts/renesas/r8a7796-salvator-x.dts b/arch/arm64/boot/dts/renesas/r8a7796-salvator-x.dts index f35e96ca7d6050b7..38bde9de3250ecbb 100644 --- a/arch/arm64/boot/dts/renesas/r8a7796-salvator-x.dts +++ b/arch/arm64/boot/dts/renesas/r8a7796-salvator-x.dts @@ -31,6 +31,11 @@ reg = <0x0 0x48000000 0x0 0x78000000>; }; + memory at 600000000 { + device_type = "memory"; + reg = <0x6 0x00000000 0x0 0x80000000>; + }; + reg_1p8v: regulator0 { compatible = "regulator-fixed"; regulator-name = "fixed-1.8V"; -- 1.9.1
