| * arch: Remove unnecessary inclusions of asm/semaphore.hMatthew Wilcox2008-04-191-1/+0Star
| | | | | | | | | | | | | | | | | | None of these files use any of the functionality promised by asm/semaphore.h. It's possible that they rely on it dragging in some unrelated header file, but I can't build all these files, so we'll have fix any build failures as they come up.

* | RealView: Move more device address definitions to board-eb.hCatalin Marinas2008-04-181-21/+21
| | | | | | | | | | | | | | | | | | | | | | | | The upcoming PB11MPCore and PB1176 have different memory maps and some of the definitions in platform.h are no longer common. This patch moves them to the board-eb.h file and updates their usage in realview_eb.c. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
* | RealView: Move the UART definitions to EB specific filesCatalin Marinas2008-04-181-16/+16
| | | | | | | | | | | | | | | | | | | | Since the PB1176 has different UART base addresses, this patch moves the definitions form platorm.h to board-eb.h. It also modifies uncompress.h to detect the platform type at run-time. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
* | RealView: Move the timer definitions into the EB specific filesCatalin Marinas2008-04-183-23/+32
| | | | | | | | | | | | | | | | | | | | | | | | This patch moves the timer definitions from platform.h into board-eb.h as they are different on PB11MPCore and PB1176. It also adds timerX_va_base variables in core.c which are set by the realview_eb_timer_init function before invoking realview_timer_init. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
* | RealView: Move the flash definitions out of platform.hCatalin Marinas2008-04-183-9/+14
| | | | | | | | | | | | | | | | | | | | This patch moves the patch definitions into board-eb.h and realview_eb.c (from core.c) as they are different on the PB11MPCore and PB1176 platforms. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
* | RealView: Move the EB GIC definitions to the board fileCatalin Marinas2008-04-181-8/+8
| | | | | | | | | | | | | | | | This is in preparation for the RealView PB11MPCore and PB1176 patches which have different base addresses for the GIC. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
* | Add RealView/EB support for the LAN9118 Ethernet chipCatalin Marinas2008-04-181-8/+31
| | | | | | | | | | | | | | | | RealView/EB revD platform comes with the SMSC LAN9118 Ethernet chip. This patch allows either the smc91x or the smc911x drivers to be used with the RealView/EB platform. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
* | RealView: Move the SCU initialisation out of __v6_setupCatalin Marinas2008-04-181-8/+35
|/ | | | | | | | | 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] 4822/1: RealView: Change the REALVIEW_MPCORE configuration optionCatalin Marinas2008-02-042-13/+10Star
| | | | | | | | 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>
* [ARM] 4821/1: RealView: Remove the platform dependencies from localtimer.cCatalin Marinas2008-02-043-5/+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.

* [ARM] 4820/1: RealView: Select the timer IRQ at run-timeCatalin Marinas2008-02-043-13/+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>
* [ARM] 4819/1: RealView: Fix entry-macro.S to work with multiple platformsCatalin Marinas2008-02-043-2/+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>
* [ARM] 4818/1: RealView: Add core-tile detectionCatalin Marinas2008-02-042-44/+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>
* [ARM] 4817/1: RealView: Move the AMBA resource definitions to realview_eb.cCatalin Marinas2008-02-043-83/+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.

* [ARM] 4816/1: RealView: Move the platform-specific definitions into board-eb.hCatalin Marinas2008-02-043-4/+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.

* [ARM] 4815/1: RealView: Add clockevents suport for the local timersCatalin Marinas2008-02-041-29/+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>
* [ARM] 4814/1: RealView: Add broadcasting clockevents support for ARM11MPCoreCatalin Marinas2008-02-044-4/+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.

| | | | | | | | | | | 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.

* [ARM] 4201/1: SMP barriers pair needed for the secondary boot processCatalin Marinas2007-02-161-0/+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>

* [ARM] 4109/2: Add support for the RealView/EB MPCore revC platformCatalin Marinas2007-02-152-2/+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.

* [ARM] 4108/2: Allow multiple GIC interrupt controllers in a systemCatalin Marinas2007-02-152-3/+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).
