This code should support the BCM4707, +BCM4708, BCM4709, BCM53010, BCM53011 and BCM53012 SoC. It uses one or +two ARM Cortex A9 Cores, some highlights are 2 PCIe 2.0 controllers, +4 Gigabit Ethernet MACs and a USB 3.0 host controller. + +This SoC uses a dual core CPU, but this is currently not implemented. +More information about this SoC can be found here: +http://www.anandtech.com/show/5925/broadcom-announces-bcm4708x-and-bcm5301x-socs-for-80211ac-routers + +Signed-off-by: Hauke Mehrtens +Acked-by: Arnd Bergmann +Acked-by: Christian Daudt +Signed-off-by: Matt Porter +--- + Documentation/devicetree/bindings/arm/bcm4708.txt | 8 ++++++ + MAINTAINERS | 8 ++++++ + arch/arm/configs/multi_v7_defconfig | 1 + + arch/arm/mach-bcm/Kconfig | 26 +++++++++++++++++++ + arch/arm/mach-bcm/Makefile | 1 + + arch/arm/mach-bcm/bcm_5301x.c | 28 +++++++++++++++++++++ + 6 files changed, 72 insertions(+) + create mode 100644 Documentation/devicetree/bindings/arm/bcm4708.txt + create mode 100644 arch/arm/mach-bcm/bcm_5301x.c + +--- /dev/null ++++ b/Documentation/devicetree/bindings/arm/bcm4708.txt +@@ -0,0 +1,8 @@ ++Broadcom BCM4708 device tree bindings ++------------------------------------------- ++ ++Boards with the BCM4708 SoC shall have the following properties: ++ ++Required root node property: ++ ++compatible = "brcm,bcm4708"; +--- a/MAINTAINERS ++++ b/MAINTAINERS +@@ -1883,6 +1883,14 @@ F: arch/arm/boot/dts/bcm2835* + F: arch/arm/configs/bcm2835_defconfig + F: drivers/*/*bcm2835* + ++BROADCOM BCM5301X ARM ARCHICTURE ++M: Hauke Mehrtens ++L: linux-arm-kernel@lists.infradead.org ++S: Maintained ++F: arch/arm/mach-bcm/bcm_5301x.c ++F: arch/arm/boot/dts/bcm5301x.dtsi ++F: arch/arm/boot/dts/bcm470* ++ + BROADCOM TG3 GIGABIT ETHERNET DRIVER + M: Nithin Nayak Sujir + M: Michael Chan +--- a/arch/arm/configs/multi_v7_defconfig ++++ b/arch/arm/configs/multi_v7_defconfig +@@ -11,6 +11,7 @@ CONFIG_ARCH_MVEBU=y + CONFIG_MACH_ARMADA_370=y + CONFIG_MACH_ARMADA_XP=y + CONFIG_ARCH_BCM=y ++CONFIG_ARCH_BCM_5301X=y + CONFIG_ARCH_BCM_MOBILE=y + CONFIG_ARCH_BERLIN=y + CONFIG_MACH_BERLIN_BG2=y +--- a/arch/arm/mach-bcm/Kconfig ++++ b/arch/arm/mach-bcm/Kconfig +@@ -32,6 +32,32 @@ config ARCH_BCM_MOBILE + BCM11130, BCM11140, BCM11351, BCM28145 and + BCM28155 variants. + ++config ARCH_BCM_5301X ++ bool "Broadcom BCM470X / BCM5301X ARM SoC" if ARCH_MULTI_V7 ++ depends on MMU ++ select ARM_GIC ++ select CACHE_L2X0 ++ select HAVE_ARM_SCU if SMP ++ select HAVE_ARM_TWD if SMP ++ select HAVE_SMP ++ select COMMON_CLK ++ select GENERIC_CLOCKEVENTS ++ select ARM_GLOBAL_TIMER ++ select CLKSRC_ARM_GLOBAL_TIMER_SCHED_CLOCK ++ select MIGHT_HAVE_PCI ++ help ++ Support for Broadcom BCM470X and BCM5301X SoCs with ARM CPU cores. ++ ++ This is a network SoC line mostly used in home routers and ++ wifi access points, it's internal name is Northstar. ++ This inclused the following SoC: BCM53010, BCM53011, BCM53012, ++ BCM53014, BCM53015, BCM53016, BCM53017, BCM53018, BCM4707, ++ BCM4708 and BCM4709. ++ ++ Do not confuse this with the BCM4760 which is a totally ++ different SoC or with the older BCM47XX and BCM53XX based ++ network SoC using a MIPS CPU, they are supported by arch/mips/bcm47xx ++ + endmenu + + endif +--- a/arch/arm/mach-bcm/Makefile ++++ b/arch/arm/mach-bcm/Makefile +@@ -13,3 +13,4 @@ + obj-$(CONFIG_ARCH_BCM_MOBILE) := board_bcm281xx.o bcm_kona_smc.o bcm_kona_smc_asm.o kona.o + plus_sec := $(call as-instr,.arch_extension sec,+sec) + AFLAGS_bcm_kona_smc_asm.o :=-Wa,-march=armv7-a$(plus_sec) ++obj-$(CONFIG_ARCH_BCM_5301X) += bcm_5301x.o +--- /dev/null ++++ b/arch/arm/mach-bcm/bcm_5301x.c +@@ -0,0 +1,28 @@ ++/* ++ * Broadcom BCM470X / BCM5301X ARM platform code. ++ * ++ * Copyright 2013 Hauke Mehrtens ++ * ++ * Licensed under the GNU/GPL.
