2008-02-04[ARM] 4822/1: RealView: Change the REALVIEW_MPCORE configuration optionCatalin Marinas2-13/+10
This patch changes the REALVIEW_MPCORE configuration option to REALVIEW_EB_ARM11MP since this is only specific to RealView/EB. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-02-04[ARM] 4821/1: RealView: Remove the platform dependencies from localtimer.cCatalin Marinas3-5/+16
This patch removes the TWD_BASE macro used to set up and configure the local timers on ARM11MPCore. The twd_base_addr and twd_size variables are defined in localtimer.c and set from the realview_eb_init function. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-02-04[ARM] 4820/1: RealView: Select the timer IRQ at run-timeCatalin Marinas3-13/+24
This patch sets the timer IRQ at run-time by moving the sys_timer structure and the timer_init function to the realview_eb.c file. This allows multiple RealView platforms to be compiled in the same kernel image. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-02-04[ARM] 4819/1: RealView: Fix entry-macro.S to work with multiple platformsCatalin Marinas3-2/+8
This patch modifies the get_irqnr_preamble macro to work with multiple platforms at run-time by reading the address of the GIC controller from the gic_cpu_base_addr variable. This variable is defined in core.c and intialised in realview_eb.c (gic_init_irq). Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-02-04[ARM] 4818/1: RealView: Add core-tile detectionCatalin Marinas2-44/+61
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. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-02-04[ARM] 4817/1: RealView: Move the AMBA resource definitions to realview_eb.cCatalin Marinas3-83/+123
This patch moves the IRQ and DMA definitions from core.h into realview_eb.c since they are platform-specific. It adds a realview_eb11mp_fixup function to adjust the IRQ numbers if the ARM11MPCore tile is fitted. The realview_smc91x_device is also moved from core.c into realview_eb.c. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-02-04[ARM] 4816/1: RealView: Move the platform-specific definitions into board-eb.hCatalin Marinas3-4/+5
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.

2008-02-04[ARM] 4815/1: RealView: Add clockevents suport for the local timersCatalin Marinas1-29/+65
This patch registers the local timers on ARM11MPCore as clock event devices. The clock device can be set up as periodic or oneshot. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-02-04[ARM] 4814/1: RealView: Add broadcasting clockevents support for ARM11MPCoreCatalin Marinas4-4/+54
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. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-02-04[ARM] 4812/1: RealView: clockevents support for the RealView platformsCatalin Marinas1-12/+66
The patch updates the RealView code to the clockevents infrastructure. The SMP support is implemented in subsequent patches. Based on the Versatile implementation by Kevin Hilman. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-02-04[ARM] 4811/1: RealView: clocksource support for the RealView platformsCatalin Marinas1-42/+31
The patch updates the RealView platform code to use the generic clocksource infrastructure for basic time keeping. Based on the Versatile implementation by Kevin Hilman. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-01-28[ARM] Fix timer damage from d3d74453c34f8fd87674a8cf5b8a327c68f22e99Russell King1-4/+0
Move the xtime write mode seqlock into timer_tick(), so it only surrounds the call to do_timer(). This avoids a deadlock in update_process_times() ... hrtimer_get_softirq_time() which tries to get a read mode seqlock on xtime, thereby preventing booting. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-09-13[ARM] realview: disable second GIC on RevB MPCore platformsRussell King1-1/+1
The second GIC asserts a permanent interrupt on Rev.B MPCore platforms. Disable initialisation of this GIC to avoid unbootable systems. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-02-16[ARM] 4201/1: SMP barriers pair needed for the secondary boot processCatalin Marinas1-0/+2
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>
2007-02-15[ARM] 4130/1: Add L220 support to RealView/EBCatalin Marinas2-0/+12
This patch enables the L220 on the RealView/EB MPCore platform. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-02-15[ARM] 4109/2: Add support for the RealView/EB MPCore revC platformCatalin Marinas2-2/+12
The kernel originally supported revB only. This patch enables revC by default and adds a config option for building the kernel for the revB platform. Since the SCU base address was hard-coded in the proc-v6.S file (and only valid for RealView/EB revB), this patch also adds a more generic support for defining the SCU information.

2007-02-15[ARM] 4108/2: Allow multiple GIC interrupt controllers in a systemCatalin Marinas2-3/+3
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).

2006-07-02[PATCH] ARM: fixup irqflags breakage after ARM genirq mergeThomas Gleixner1-1/+1

2006-01-07[ARM] Move AMBA include files to include/linux/amba/Russell King3-4/+5

2006-01-03[ARM] Remove clk_use()/clk_unuse()Russell King1-11/+0
It seems that clk_use() and clk_unuse() are additional complexity which isn't required anymore. Remove them from the clock framework to avoid the additional confusion which they cause, and update all ARM machine types except for OMAP. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
