2009-05-31[ARM] Kconfig: remove 'default n'Russell King
Kconfig entries default to n, so there's no need for this to be explicitly specified. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-05-30RealView: Move the IRQ_* definitions out of the board-*.h filesCatalin Marinas
The IRQ_* macros need to be made visible via the mach/irqs.h file but without the additional macros defined in the board-*.h files. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2009-05-30RealView: Toggle one LED per CPUCatalin Marinas
If CONFIG_LEDS is enabled, it makes more sense to toggle one LED per CPU in SMP systems rather than a single LED for all the CPUs. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2009-05-30RealView: Allow access to the secure flash memory block on PB1176Catalin Marinas
This patch adds a Kconfig option for specifying whether Linux will only be run in secure mode on the RealView PB1176 platform. Enabling it will make the secure flash memory block (64MB @ 0x3c000000) available to Linux. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2009-05-30RealView: Add support for the RealView/PBX platformColin Tuckley
This is a RealView platform supporting core tiles with ARM11MPCore, Cortex-A8 or Cortex-A9 (multicore) processors. It has support for MMC, CompactFlash, PCI-E. Signed-off-by: Colin Tuckley <colin.tuckley@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

2009-05-17[ARM] smp: SCU is used on non-realview platformsRussell King
The SCU can be used by non-realview platforms, so make it visible for other people to use rather than having them copy the header file. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2009-05-17[ARM] realview: fix broadcast tick supportRussell King
Having discussed broadcast tick support with Thomas Glexiner, the broadcast tick devices should be registered with a higher rating than the global tick device, and it should have the ONESHOT and PERIODIC feature flags set.

2009-05-17[ARM] realview: remove useless smp_cross_call_done()Russell King
smp_cross_call_done() is a no-op for MPCore, and since it's only used by platform code, there's no point in having it unless it's doing something. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-05-17[ARM] smp: fix cpumask usage in ARM SMP codeRussell King
The ARM SMP code wasn't properly updated for the cpumask changes, which results in smp_timer_broadcast() broadcasting ticks to non-online CPUs. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2009-04-02[ARM] 5444/1: ARM: Realview: Fix event-device multiplicators in localtimer.cSantosh Shilimkar
Set the "mult" to finite value in the local_timer_setup in case of CONFIG_LOCAL_TIMERS not enabled. Othewise this throws warning in the boot log because of detect zero event-device multiplicators. This can cause division-by-zero crashes. Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-03-19[ARM] pass reboot command line to arch_reset()Russell King
OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). This patch fixes things to pass this string to arch_reset(). This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.

2009-02-19[ARM] 5397/1: RealView: Add support for the ISP1761 USB chipCatalin Marinas

2009-02-19[ARM] 5396/1: RealView: Use PATA_PLATFORM to access the CompactFlashCatalin Marinas
This driver adds the platform_device definitions to allow the use of CompactFlash on the RealView PB11MPCore and PB-A8 platforms. Note that the CompactFlash controller is expected to be initialised by the Boot Monitor and support the True IDE mode.

2009-02-19[ARM] 5395/1: RealView: Add support for the DS1338 RTC chipCatalin Marinas

2008-12-13cpumask: convert struct clock_event_device to cpumask pointers.Rusty Russell
Impact: change calling convention of existing clock_event APIs struct clock_event_timer's cpumask field gets changed to take pointer, as does the ->broadcast function. Another single-patch change. For safety, we BUG_ON() in clockevents_register_device() if it's not set. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Cc: Ingo Molnar <mingo@elte.hu>

2008-12-01RealView: Select CPU_V6 for MACH_REALVIEW_PB11MPCatalin Marinas
This seems to be missing from the arm:devel branch, though the other RealView configurations were modified accordingly. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-12-01RealView: Allow the in-kernel smc911x.c driver on RealViewCatalin Marinas
This patch adds smc911x.c device configuration to the RealView platforms. At some point it may be changed to the new smsc911x.c driver (once complete testing was done). Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

2008-12-01RealView: Use only the shadow mapping of ARM11MPCore local timersCatalin Marinas
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>

2008-12-01RealView: Allow PHYS_OFFSET at 0x70000000Catalin Marinas
RealView boards like PB11MPCore have 512MB of RAM available contiguously at 0x70000000. Half of the memory is mirrored at 0x00000000 for backwards compatibility. This patch adds the CONFIG_REALVIEW_HIGH_PHYS_OFFSET option option to change the physical base address so that the full amount of RAM is available to Linux. Note that the EB board has 256MB of RAM also mirrored at 0x70000000, the only board without this feature being PB1176. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-11-30[ARM] Add a common typesafe __io implementationRussell King
As Al did for Versatile in 2ad4f86b60b649fd7428265c08d73a3bd360c81b, add a typesafe __io implementation for platforms to use. Convert platforms to use this new simple typesafe implementation. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-11-29[ARM] Hide ISA DMA API when ISA_DMA_API is unsetRussell King
When ISA_DMA_API is unset, we're not implementing the ISA DMA API, so there's no point in publishing the prototypes via asm/dma.h, nor including the machine dependent parts of that API. This allows us to remove a lot of mach/dma.h files which don't contain any useful code. Unfortunately though, some platforms put their own private non-ISA definitions into mach/dma.h, so we leave these behind and fix the appropriate #include statments.

2008-11-28[ARM] remove a common set of __virt_to_bus definitionsNicolas Pitre
Let's provide an overridable default instead of having every machine class define __virt_to_bus and __bus_to_virt to the same thing. What most platforms are using is bus_addr == phys_addr so such is the default. One exception is ebsa110 which has no DMA what so ever, so the actual definition is not important except only for proper compilation. Also added a comment about the special footbridge bus translation. Let's also remove comments alluding to set_dma_addr which is not (and should not) be commonly used.

2008-11-27[ARM] realview: convert to clkdev and lookup clocks by device nameRussell King
People often point to the Integrator/Versatile/Realview implementations to justify using the consumer name as the sole selector for clocks.

2008-11-10RealView: Make more vmalloc space by changing IO_ADDRESSCatalin Marinas
Since boards like PB11MPCore have 512MB of RAM and 128MB of flash, the virtual space is short on vmalloc memory and mapping the flash fails. This patch changes the IO_ADDRESS so that static mappings start at 0xfc000000 and moves the PCI virtual addresses higher up. The new VMALLOC_END is set to 0xf8000000 (512MB higher than the old value). Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
2008-11-10RealView: Add debug-macro.S support for the PB1176 platformCatalin Marinas
The UART0 address is different on PB1176 from EB or PB11MPCore. This patch adds the necessary #ifdef's to this file. The disadvantage is that enabling CONFIG_DEBUG_LL will work properly on PB1176 if only this platform is enabled. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
