new mvebu/armada-370 boot failure (was: mainline boot: 33 pass, 3 fail (v3.13-8631-gba635f8))

Note that it only fails on multi_v7_defconfig, and not mvebu_defconfig. When it fails, there's no useful console output, but it was bisected down to: first bad commit: [af8d1c63afcbf36eea06789c92e22d4af118d2fb] ARM: mvebu: Add support to get the ID and the revision of a SoC. Based on an idea from Jason, I added CONFIG_PCI=y and CONFIG_MVEBU_PCI=y to multi_v7_defconfig and that made it start booting again, some something is probably hanging when accessing PCI registers?

[PATCH 00/20] Make ACPI core running on ARM64

by Hanjun Guo

This patch set trys to make ACPI core running on ARM64. 1. Why ACPI is needed ? ACPI provides standard interfaces for power managment, themal control, device enumeration and configuration and etc. So ACPI can make OS and hardware decoupling and make people upgrade software or hardware more easily. ACPI is more than that. It can provide standard error report interface called ACPI Platform Error Interface (APEI) for RAS features, and provide standard interface for dynamic system device reconfigurations such as CPU/memory/computer node hot-add and hot-remove, this is especially useful for servers. 2. Does ACPI run propably on ARM64 ? ACPI spec 5.0 introduces hardware reduced mode, GICC/GICD, GTDT for arch timer and etc for Socs. This makes it possible to run ACPI on ARM/ARM64. Some company already did that (UEFI+ACPI) on ARM platforms. ACPI spec for ARM/ARM64 is still need to be improved and people are working on that, but for now, we can run ACPI propably except for some new features such as PSCI and GICv3. 3. What we did in this patch set patch 1-8(Hanjun Guo) will make ACPI core running on ARM64 and make the compilation is ok on ARM64. patch 9-12 will enumeration cpus presented by MADT table. since PSCI is not available for ACPI 5.0, we use spin-table method for SMP initialization. patch 13-16 will initialize GIC in the system. ACPI only support one GIC and only report information about GICC and GICD, so there will some limitations for GICv3 and GICH for GICv2 for virtualization. patch 17-19 and patch from Amit will finish the arch timer initialization. We get informatiom from GTDT (Generic Timer Description Table) to initialize arch timer and introduce a macro CLOCKSOURCE_ACPI_DECLARE to do the same job as CLOCKSOURCE_OF_DECLARE to make it scalable for other timers. All the ACPI tables are available with BSD license at: git://git.linaro.org/arm/acpi/acpi-asl.git Changs since last RFC version: 1) Introduce some PCI functions when PCI is enabled 2) Select ACPI_REDUCED_HARDWARE_ONLY if ACPI is enabled 3) Remove ACPI based CPU hotplug code 4) Use spin-table method for SMP initialization 5) Add macro CLOCKSOURCE_ACPI_DECLARE for ACPI timer init 6) Address lots of comments and suggestions in last RFC version 7) Remove RFC tag and make all the patches seperated as two parts, one is "ACPI: Some patches to prepare for running ACPI on !x86 and !ia64", and another is this one. 8) Rebased on 3.13-rc8. Amit Daniel Kachhap (1): clocksource / acpi: Add macro CLOCKSOURCE_ACPI_DECLARE Hanjun Guo (19): ARM64 / ACPI: Make PCI optional for ACPI on ARM64 ARM64 : Add dummy asm/cpu.h ARM64 / ACPI: Introduce the skeleton of _PDC related for ARM64 ARM64 / ACPI: Introduce arm_core.c and its related head file ARM64 / ACPI: Introduce lowlevel suspend function ARM64 / ACPI: Introduce some PCI functions when PCI is enabled ARM64 / ACPI: Enable ARM64 in Kconfig ARM64 / ACPI: Select ACPI_REDUCED_HARDWARE_ONLY if ACPI is enabled on ARM64 ARM64 / ACPI: Implement core functions for parsing MADT table ARM64 / ACPI: Enumerate possible/present CPU set and map logical cpu id to APIC id ARM64 / ACPI: Get the enable method for SMP initialization ARM64 / ACPI: Use Parked Address in GIC structure for spin table SMP initialisation ARM64 / ACPI: Define ACPI_IRQ_MODEL_GIC needed for arm Irqchip / gic: Set as default domain so we can access from ACPI ACPI / ARM64: Update acpi_register_gsi to register with the core IRQ subsystem ACPI / GIC: Initialize GIC using the information in MADT clocksource / arch_timer: Use ACPI GTDT table to initialize arch timer clocksource / ACPI: Introduce clocksource_acpi_init() using CLOCKSOURCE_ACPI_DECLARE ARM64 / clocksource: Use clocksource_acpi_init() arch/arm64/Kconfig | 3 + arch/arm64/Makefile | 1 + arch/arm64/include/asm/acpi.h | 112 +++++++ arch/arm64/include/asm/cpu.h | 25 ++ arch/arm64/include/asm/cpu_ops.h | 1 + arch/arm64/include/asm/pci.h | 20 ++ arch/arm64/include/asm/processor.h | 2 + arch/arm64/include/asm/smp.h | 2 +- arch/arm64/kernel/cpu_ops.c | 2 +- arch/arm64/kernel/irq.c | 6 + arch/arm64/kernel/process.c | 3 + arch/arm64/kernel/setup.c | 6 + arch/arm64/kernel/smp.c | 42 ++- arch/arm64/kernel/smp_spin_table.c | 12 +- arch/arm64/kernel/time.c | 6 + arch/arm64/pci/Makefile | 1 + arch/arm64/pci/pci.c | 33 ++ drivers/acpi/Kconfig | 11 +- drivers/acpi/Makefile | 4 +- drivers/acpi/bus.c | 3 + drivers/acpi/internal.h | 7 + drivers/acpi/osl.c | 3 +- drivers/acpi/plat/Makefile | 1 + drivers/acpi/plat/arm-core.c | 599 ++++++++++++++++++++++++++++++++++ drivers/acpi/tables.c | 21 ++ drivers/clocksource/Makefile | 1 + drivers/clocksource/arm_arch_timer.c | 101 +++++- drivers/clocksource/clksrc-acpi.c | 36 ++ drivers/irqchip/irq-gic.c | 7 + include/asm-generic/vmlinux.lds.h | 10 + include/linux/acpi.h | 7 + include/linux/clocksource.h | 15 + include/linux/pci.h | 33 +- 33 files changed, 1099 insertions(+), 37 deletions(-) create mode 100644 arch/arm64/include/asm/acpi.h create mode 100644 arch/arm64/include/asm/cpu.h create mode 100644 arch/arm64/include/asm/pci.h create mode 100644 arch/arm64/pci/Makefile create mode 100644 arch/arm64/pci/pci.c create mode 100644 drivers/acpi/plat/Makefile create mode 100644 drivers/acpi/plat/arm-core.c create mode 100644 drivers/clocksource/clksrc-acpi.c -- 1.7.9.5

[PATCH] spi/s3c64xx: Split wait_for_xfer() into PIO and DMA versions

From: Mark Brown <broonie(a)linaro.org> There is no meaningful code sharing between the PIO and DMA variants (just the timeout calculation) so in order to make the code easier to work with split the two cases. Looking at the code it is not clear how the PIO version works for large transmits, greater than FIFO size is only handled for RX.
