From 6c3ff8b11a16ec69199ab85b74a5fae6d9c59db7 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Wed, 30 Oct 2013 18:21:09 -0700 Subject: ARM: Introduce CPU_METHOD_OF_DECLARE() for cpu hotplug/smp The goal of multi-platform kernels is to remove the need for mach directories and machine descriptors. To further that goal, introduce CPU_METHOD_OF_DECLARE() to allow cpu hotplug/smp support to be separated from the machine descriptors. Implementers should specify an enable-method property in their cpus node and then implement a matching set of smp_ops in their hotplug/smp code, wiring it up with the CPU_METHOD_OF_DECLARE() macro. When the kernel is compiled we'll collect all the enable-method smp_ops into one section for use at boot. At boot time we'll look for an enable-method in each cpu node and try to match that against all known CPU enable methods in the kernel. If there are no enable-methods in the cpu nodes we fallback to the cpus node and try to use any enable-method found there. If that doesn't work we fall back to the old way of using the machine descriptor.

The board-v7.c name as we expect this file to ultimately contain the DT_MACHINE_START definitions for all ARMv7 Marvell EBU platforms (370, 375, 38x, XP and Dove as of today). In relation to this file rename, this commit also: * Renames the hidden Kconfig symbol MACH_ARMADA_370_XP to MACH_MVEBU_V7. This hidden symbol is selected by the various per-SoC visible Kconfig options to trigger the build of board-v7.c. * Renames a certain number of functions in board-v7.c so that their armada_370_xp prefix is replaced by a mvebu prefix. The .dt_compat array keeps its armada_370_xp prefix because the new SOCs will be introduced with separate .dt_compat arrays, due to the need for different SMP operations.

These SoCs share most of their IP with the Armada 370/XP SoCs. The main difference is the use of a Cortex A9 CPU instead of the PJ4B CPU. The Armada 380 is a single core Cortex-A9, while the Armada 385 is a dual-core Cortex-A9. The support is introduced in board-v7.c, together with Armada 370/XP, but a separate DT structure is added, because Armada 38x will need a different set of SMP operations when the SMP support is introduced.

In order to help Debian transition between mach-kirkwood and mach-mvebu, the DTS files are compiled for both, allowing Debian to continue using mach-kirkwood until all remaining boards are supported by mach-mvebu. Debian is then expected to simply swap from mach-kirkwood to mach-mvebu and mach-kirkwood will be removed.

Selecting ARCH_KIRKWOOD and MACH_KIRKWOOD is necessary during the migration from mach-kirkwood to mach-mvebu. Until the last four legacy kirkwood board files have a DT equivalent, we need to support building DT from both mach-kirkwood and mach-mvebu.

However, additional SoCs now leverage the OMAP4 clockdomain code so update it to use SW_SLEEP if the clockdomain data specifies that the CLKDM has the CLKDM_CAN_FORCE_SLEEP flag set rather than using HW_AUTO for both cases. Without this patch, clockdomain handling is broken on AM43xx and no clockdomains are actually being put into idle on this platform. Any attempt to idle them results in the HW_AUTO value (0x3) being written to them with no apparent effect.

Also, the arrays are only taken as the 5th argument for the imx_clk_mux() function, which is in the type of 'const char **parents'. So, let's remove the 2nd const specifier right after 'char'.

To achieve that, we need to copy the suspend code to ocram and run the low level hardware related code(set DDR IOs to high-Z state) in ocram. If there is no ocram space available, then system will still do suspend in external DDR, hence no DDR IOs will be set to high-Z. The OCRAM usage layout is as below, ocram suspend region(4K currently): ======================== high address ====================== . . . ^ ^ ^ imx6_suspend code PM_INFO structure(imx6_cpu_pm_info) ======================== low address ======================= Reviewed-by: Sascha Hauer Signed-off-by: Anson Huang Signed-off-by: Shawn Guo --- arch/arm/mach-imx/Makefile | 3 +- arch/arm/mach-imx/common.h | 6 +- arch/arm/mach-imx/hardware.h | 4 +- arch/arm/mach-imx/mach-imx6q.c | 2 +- arch/arm/mach-imx/mach-imx6sl.c | 3 +- arch/arm/mach-imx/pm-imx6q.c | 281 ++++++++++++++++++++++++++++++++++++- arch/arm/mach-imx/suspend-imx6.S | 289 +++++++++++++++++++++++++++++++++++++++ 7 files changed, 577 insertions(+), 11 deletions(-) create mode 100644 arch/arm/mach-imx/suspend-imx6.S diff --git a/arch/arm/mach-imx/Makefile b/arch/arm/mach-imx/Makefile index 21114a9a2ae7..48b47aa6224a 100644 --- a/arch/arm/mach-imx/Makefile +++ b/arch/arm/mach-imx/Makefile @@ -102,7 +102,8 @@ obj-$(CONFIG_HOTPLUG_CPU) += hotplug.o obj-$(CONFIG_SOC_IMX6Q) += clk-imx6q.o mach-imx6q.o obj-$(CONFIG_SOC_IMX6SL) += clk-imx6sl.o mach-imx6sl.o -obj-$(CONFIG_SOC_IMX6Q) += pm-imx6q.o headsmp.o +AFLAGS_suspend-imx6.o :=-Wa,-march=armv7-a +obj-$(CONFIG_SOC_IMX6Q) += pm-imx6q.o headsmp.o suspend-imx6.o # i.MX6SL reuses i.MX6Q code obj-$(CONFIG_SOC_IMX6SL) += pm-imx6q.o headsmp.o diff --git a/arch/arm/mach-imx/common.h b/arch/arm/mach-imx/common.h index b909b689619b..91d69ccf7c76 100644 --- a/arch/arm/mach-imx/common.h +++ b/arch/arm/mach-imx/common.h @@ -1,5 +1,5 @@ /* - * Copyright 2004-2013 Freescale Semiconductor, Inc.

[ 0.037768] imx6_pm_common_init: failed to initialize ocram suspend -19! This happens because CONFIG_SRAM is not selected by default in multi_v7_defconfig. Fix this by selecting CONFIG_SRAM at ARCH_MXC level, so that other SoCs could use the SRAM driver as well. As SRAM automatically selects GENERIC_ALLOCATOR, just drop it from the Kconfig entry.

With kernel 3.10 I have also seen this fault at different places in the boot process, but starting with 3.11 they are always occurring after the "Freeing unused kernel memory" message. I never was able to completely boot to userspace without this handler. The abort code is constant 0x1c06. This fault just happens once in the boot process I have never seen it happing twice or more. I also tried changing the CPSR.A bit to 0 in init_early, with this code like Afzal suggested, but that did not change anything: asm volatile("mrs r12, cpsr\n" "bic r12, r12, #0x00000100\n" "msr cpsr_c, r12" ::: "r12", "cc", "memory"); Disabling the L2 cache by building with CONFIG_CACHE_L2X0 unset did not help. This workaround was copied from the vendor code including most of the comments. It says it they think this is caused by the CFE boot loader used on this device. I do not have any access to any datasheet or errata document to check this.
