* RealView: Clean up the machine_is_*() calls in platsmp.cCatalin Marinas2008-12-01
| | | | | | | | | | | Some of the calls weren't necessary and some others were duplicated. This patch tidies up the platsmp.c file. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
* RealView: Use only the shadow mapping of ARM11MPCore local timersCatalin Marinas2008-12-01
| | | | | | | | | | | | All the cases where the local timer for a CPU is accessed happen on the corresponding current CPU, hence no need to access the per-CPU local timer mappings. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
* RealView: Add Cortex-A9 support to the EB boardJon Callan2008-12-01
| | | | | | | | | | | This patch adds the necessary definitions and Kconfig entries to enable Cortex-A9 (ARMv7 SMP) tiles on the RealView/EB board. Signed-off-by: Jon Callan <Jon.Callan@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
* [ARM] Convert asm/io.h to linux/io.hRussell King2008-09-06

* [ARM] Move include/asm-arm/arch-* to arch/arm/*/include/machRussell King2008-08-07
| | | | | | This just leaves include/asm-arm/plat-* to deal with. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] Remove asm/hardware.h, use asm/arch/hardware.h insteadRussell King2008-08-07
| | | | | | | | | Remove includes of asm/hardware.h in addition to asm/arch/hardware.h. Then, since asm/hardware.h only exists to include asm/arch/hardware.h, update everything to directly include asm/arch/hardware.h and remove asm/hardware.h. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] 5131/1: Annotate platform_secondary_init with trace_hardirqs_offCatalin Marinas2008-06-30
| | | | | | | | | This patch annotates the platform_secondary_init function in arch/arm/mach-realview/platsmp.c with trace_hardirqs_off to avoid a warning when LOCKDEP and TRACE_IRQFLAGS are enabled.

* RealView: Add the SMP initialisation support for PB11MPCoreCatalin Marinas2008-04-18
| | | | | | | | | | | | This patch adds the initialisation calls for the SMP support on the PB11MPCore platform. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
* RealView: Move the SCU initialisation out of __v6_setupCatalin Marinas2008-04-18
| | | | | | | | | This patch moves the SCU initialisation from __v6_setup to the smp_prepare_cpus() function as it relies on platform-specific settings. Changes to get_core_count() are mainly for allowing cleaner code with the upcoming PB11MPCore patches. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
* [ARM] 4818/1: RealView: Add core-tile detectionCatalin Marinas2008-02-04
| | | | | | | | | This patch adds the core-tile detection and only enables devices if the corresponding tile is present. It currently detects the ARM11MPCore via the core_tile_eb11mp() macro.

* [ARM] 4816/1: RealView: Move the platform-specific definitions into board-eb.hCatalin Marinas2008-02-04
| | | | | | | | | | | | | This patch moves the platform specific definitions from platform.h into the board-eb.h file. It drops the INT_* definitions as they are no longer used in irqs.h (moved to board-eb.h). It renames REALVIEW_* macros to REALVIEW_EB_* or REALVIEW_EB11MP_* to distinguish between standard EB and EB + the ARM11MPCore tile. The platform.h file contains common definitions to the RealView platforms and it is only directly included in board-*.h files.

* [ARM] 4814/1: RealView: Add broadcasting clockevents support for ARM11MPCoreCatalin Marinas2008-02-04
| | | | | | | | | | | | | This patch adds dummy local timers for each CPU so that the board clock device is used to broadcast events to the other CPUs. The patch also adds the declaration for the dummy_timer_setup function (the equivalent of local_timer_setup when CONFIG_LOCAL_TIMERS is not set). Due to the way clockevents work, the dummy timer on the first CPU has to be registered before the board timer.

* [ARM] 4201/1: SMP barriers pair needed for the secondary boot processCatalin Marinas2007-02-16
| | | | | | | | | | In some situations, the pen_release store in platform_secondary_init() may stay forever in the write buffer while the CPU is waiting on the boot_lock to be released in boot_secondary(). The primary CPU could never see the pen_release update without the barriers. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* [ARM] 4108/2: Allow multiple GIC interrupt controllers in a systemCatalin Marinas2007-02-15
| | | | | | | | | The current implementation only assumes one GIC to be present in the system. However, there are platforms with more than one cascaded interrupt controllers (RealView/EB MPCore for example).

* [ARM] Fix arch-realview/system.h to use __io_address()Russell King2005-11-16
