This patch adds a workaround for the 458692 Cortex-A8 (r2p0) erratum. It sets the corresponding bits in the auxiliary control register so that the PLD instruction becomes a NOP. Signed-off-by:

According to the ARM11MPCore Erratum 351422 (r0p0), under extremely rare conditions, in an MPCore node consisting of at least 3 CPUs, two CPUs trying to perform a STREX to data on the same shared cache line can enter a livelock situation. This patch adds variable spinning time to the locking routines. Signed-off-by:

Errata 411920 - Invalidation of the Instruction Cache operation can fail. This Errata is present in 1136, 1156 and 1176. It does not affect the MPCore. This patch implements the ARM Ltd recommended workaround. Signed-off-by:

This patch is a workaround for the 364296 ARM1136 r0pX errata (possible cache data corruption with hit-under-miss enabled). It sets the undocumented bit 31 in the auxiliary control register and the FI bit in the control register, thus disabling hit-under-miss without putting the processor into full low interrupt latency mode.

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:

This patch enables the use of the Advanced SIMD (NEON) extension on ARMv7. The NEON technology is a 64/128-bit hybrid SIMD architecture for accelerating the performance of multimedia and signal processing applications. The extension shares the registers with the VFP unit and enabling/disabling and saving/restoring follow the same rules. In addition, there are instructions that do not have the appropriate CP number encoded, the checks being made in the call_fpe function. Signed-off-by:

'select' used by config symbol 'INTEL_IOATDMA' refers to undefined symbol 'DCA' Although drivers/dma is currently the only user future drivers outside of drivers/dma may select this option so it is better to add this to arch/arm/Kconfig than move DCA to drivers/dma/Kconfig. Signed-off-by:

Commit 09cadedb ("Combine instrumentation menus in kernel/Kconfig.instrumentation") broke ARM profiling support, since ARM has some extra Kconfig options and doesn't just use the common OPROFILE/KPROBES config options. Rather than just revert the thing outright, or add ARM-specific knowledge to the generic Kconfig.instrumentation file (where the only and whole point was to be generic, not too architecture-specific), this just makes ARM not use the generic version, since it doesn't suit it. So create an arm-specific version of Kconfig.instrumentation instead, and use that. Acked-by:

Most of these fixes were already submitted for old kernel versions, and were approved, but for some reason they never made it into the releases. Because this is a consolidation of a couple old missed patches, it touches both Kconfigs and documentation texts. Signed-off-by:

Quoting Randy: "It seems sad that this patch sources Kconfig.marker, a 7-line file, 20-something times. Yes, you (we) don't want to put those 7 lines into 20-something different files, so sourcing is the right thing. However, what you did for avr32 seems more on the right track to me: make _one_ Instrumentation support menu that includes PROFILING, OPROFILE, KPROBES, and MARKERS and then use (source) that in all of the arches."

Bugfixes for the OSK led support: - Fix Kconfig merge glitches: Mistral handles idle and timer leds just fine - Fix pm_suspend() runtime botch: can't sleep, so can't touch tps65010 leds Improvements: - Switch sense of Mistral idle led, so idle == off Probably the TPS65010 leds should be handled only by the "new led" API.

Support for generic input output for MX1 family. The implementation prevents allocation of one pin by two users, but does not store pointer to the user description permanently, because this solution would have bigger memory overhead. The simple way to integrate code with per BSP pins setup and allocation is required else all GPIO registration checking is useless. The function imx_gpio_setup_multiple_pins() can be used for this purpose in future. Signed-off-by:
