bcm53xx: add initial support for ARM based BCM47XX and BCM53XX SoCs
This was only tested on a Netgear R6250, but it could also work on
other devices when the correct images are generated.
It is only possible to boot into a ram disk, no Ethernet, Wifi, flash,
USB is supported.

Add ARM global timer + support. + +This is a simple driver for the global timer module found in the Cortex +A9-MP cores from revision r1p0 onwards. This should be able to perform +the functions of the system timer and the local timer in an SMP system. + +The global timer has the following features: + The global timer is a 64-bit incrementing counter with an +auto-incrementing feature. It continues incrementing after sending +interrupts. The global timer is memory mapped in the private memory +region. + The global timer is accessible to all Cortex-A9 processors in the +cluster. Each Cortex-A9 processor has a private 64-bit comparator that +is used to assert a private interrupt when the global timer has reached +the comparator value. All the Cortex-A9 processors in a design use the +banked ID, ID27, for this interrupt. ID27 is sent to the Interrupt +Controller as a Private Peripheral Interrupt. The global timer is +clocked by PERIPHCLK. + +Signed-off-by: Stuart Menefy <stuart.menefy@st.com> +Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@st.com> +CC: Arnd Bergmann <arnd@arndb.de> +CC: Rob Herring <robherring2@gmail.com> +CC: Linus Walleij <linus.walleij@linaro.org> +CC: Will Deacon <will.deacon@arm.com> +CC: Thomas Gleixner <tglx@linutronix.de> +--- + .../devicetree/bindings/arm/global_timer.txt | 21 ++ + drivers/clocksource/Kconfig | 13 + + drivers/clocksource/Makefile | 1 + + drivers/clocksource/arm_global_timer.c | 325 ++++++++++++++++++++ + 4 files changed, 360 insertions(+) + create mode 100644 Documentation/devicetree/bindings/arm/global_timer.txt + create mode 100644 drivers/clocksource/arm_global_timer.c + +--- /dev/null ++++ b/Documentation/devicetree/bindings/arm/global_timer.txt +@@ -0,0 +1,21 @@ ++ ++* ARM Global Timer ++ Cortex-A9 are often associated with a per-core Global timer. ++ ++** Timer node required properties: ++ ++- compatible : Should be "arm,cortex-a9-global-timer" ++ Driver supports versions r2p0 and above. ++ ++- interrupts : One interrupt to each core ++ ++- reg : Specify the base address and the size of the GT timer ++ register window. ++ ++Example: ++ ++ timer@2c000600 { ++ compatible = "arm,cortex-a9-global-timer"; ++ reg = <0x2c000600 0x20>; ++ interrupts = <1 13 0xf01>; ++ }; +--- a/drivers/clocksource/Kconfig ++++ b/drivers/clocksource/Kconfig +@@ -67,6 +67,19 @@ config ARM_ARCH_TIMER + bool + select CLKSRC_OF if OF + ++config ARM_GLOBAL_TIMER ++ bool ++ select CLKSRC_OF if OF ++ help ++ This options enables support for the ARM global timer unit ++ ++config CLKSRC_ARM_GLOBAL_TIMER_SCHED_CLOCK ++ bool ++ depends on ARM_GLOBAL_TIMER ++ default y ++ help ++ Use ARM global timer clock source as sched_clock ++ + config CLKSRC_METAG_GENERIC + def_bool y if METAG + help +--- a/drivers/clocksource/Makefile ++++ b/drivers/clocksource/Makefile +@@ -28,4 +28,5 @@ obj-$(CONFIG_CLKSRC_EXYNOS_MCT) += exyno + obj-$(CONFIG_CLKSRC_SAMSUNG_PWM) += samsung_pwm_timer.o + + obj-$(CONFIG_ARM_ARCH_TIMER) += arm_arch_timer.o ++obj-$(CONFIG_ARM_GLOBAL_TIMER) += arm_global_timer.o + obj-$(CONFIG_CLKSRC_METAG_GENERIC) += metag_generic.o +--- /dev/null ++++ b/drivers/clocksource/arm_global_timer.c +@@ -0,0 +1,325 @@ ++/* ++ * drivers/clocksource/arm_global_timer.c ++ * ++ * Copyright (C) 2013 STMicroelectronics (R&D) Limited. ++ * Author: Stuart Menefy <stuart.menefy@st.com> ++ * Author: Srinivas Kandagatla <srinivas.kandagatla@st.com> ++ * ++ * This program is free software; you can redistribute it and/or modify ++ * it under the terms of the GNU General Public License version 2 as ++ * published by the Free Software Foundation. ++ */ ++ ++#include <linux/init.h> ++#include <linux/interrupt.h> ++#include <linux/clocksource.h> ++#include <linux/clockchips.h> ++#include <linux/cpu.h> ++#include <linux/clk.h> ++#include <linux/err.h> ++#include <linux/io.h> ++#include <linux/of.h> ++#include <linux/of_irq.h> ++#include <linux/of_address.h> ++ ++#include <asm/sched_clock.h> ++#include <asm/cputype.h> ++ ++#define GT_COUNTER0 0x00 ++#define GT_COUNTER1 0x04 ++ ++#define GT_CONTROL 0x08 ++#define GT_CONTROL_TIMER_ENABLE BIT(0) /* this bit is NOT banked */ ++#define GT_CONTROL_COMP_ENABLE BIT(1) /* banked */ ++#define GT_CONTROL_IRQ_ENABLE BIT(2) /* banked */ ++#define GT_CONTROL_AUTO_INC BIT(3) /* banked */ ++ ++#define GT_INT_STATUS 0x0c ++#define GT_INT_STATUS_EVENT_FLAG BIT(0) ++ ++#define GT_COMP0 0x10 ++#define GT_COMP1 0x14 ++#define GT_AUTO_INC 0x18 ++ ++/* ++ * We are expecting to be clocked by the ARM peripheral clock. ++ * ++ * Note: it is assumed we are using a prescaler value of zero, so this is ++ * the units for all operations. ++ */ ++static void __iomem *gt_base; ++static unsigned long gt_clk_rate; ++static int gt_ppi; ++static struct clock_event_device __percpu *gt_evt; ++ ++/* ++ * To get the value from the Global Timer Counter register proceed as follows: ++ * 1.
