From 19b85c086019e54c1976fdaf56e8923f7e568091 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Tue, 23 Oct 2012 08:17:20 +0200 Subject: [PATCH] arm: mvebu: support for the PlatHome OpenBlocks AX3-4 board This platform, available in Japan from PlatHome, has a dual-core Armada XP, the MV78260. For now, only the two serial ports and the three front LEDs are supported. Support for SMP, network, SATA, USB and other peripherals will be added as drivers for them become available for Armada XP in mainline. Signed-off-by: Thomas Petazzoni Acked-by: Gregory CLEMENT Tested-by: Gregory CLEMENT --- This is 3.8 material. Changes since v2: * Renamed the .dts file to armada-xp-openblocks-ax3-4.dts * Removed the compatible string from armada-370-xp.c (which now only lists the common SoC compatible string) Changes since v1: * Renamed the board to OpenBlocks AX3-4, since there is a variant called AX3-2 which has less RAM, and no mini PCIe port. Requested by Andrew Lunn. * Fix the amount of memory to 3 GB. In fact, the board has 1 GB soldered, and 2 GB in a SODIMM slot (which is therefore removable). But as the board is delivered as is, we'll assume it has 3 GB of memory by default. --- arch/arm/boot/dts/Makefile | 3 +- .../boot/dts/armada-xp-openblocks-ax3-4.dts | 69 +++++++++++++++++++ 2 files changed, 71 insertions(+), 1 deletion(-) create mode 100644 arch/arm/boot/dts/armada-xp-openblocks-ax3-4.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index f37cf9fa5fa0..718584df3398 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -44,7 +44,8 @@ dtb-$(CONFIG_ARCH_KIRKWOOD) += kirkwood-dns320.dtb \ dtb-$(CONFIG_ARCH_MSM) += msm8660-surf.dtb \ msm8960-cdp.dtb dtb-$(CONFIG_ARCH_MVEBU) += armada-370-db.dtb \ - armada-xp-db.dtb + armada-xp-db.dtb \ + armada-xp-openblocks-ax3-4.dtb dtb-$(CONFIG_ARCH_MXC) += imx51-babbage.dtb \ imx53-ard.dtb \ imx53-evk.dtb \ diff --git a/arch/arm/boot/dts/armada-xp-openblocks-ax3-4.dts b/arch/arm/boot/dts/armada-xp-openblocks-ax3-4.dts new file mode 100644 index 000000000000..cb86853fef95 --- /dev/null +++ b/arch/arm/boot/dts/armada-xp-openblocks-ax3-4.dts @@ -0,0 +1,69 @@ +/* + * Device Tree file for OpenBlocks AX3-4 board + * + * Copyright (C) 2012 Marvell + * + * Thomas Petazzoni + * + * This file is licensed under the terms of the GNU General Public + * License version 2.
