USB resources and DMA40 configurations are dynamically with the data provided in ux500_add_usb() call.

2011-02-23ARM: 6759/1: smp: Select local timers vs broadcast timer support runtimeSantosh Shilimkar1-1/+2
The current code support of dummy timers in absence of local timer is compile time. This is an attempt to convert it to runtime so that on few SOC version if the local timers aren't supported kernel can switch to dummy timers. OMAP4430 ES1.0 does suffer from this limitation. This patch should not have any functional impact on affected files.

2010-12-20ARM: Fix subtle race in CPU pen_release hotplug codeRussell King1-7/+15
There is a subtle race in the CPU hotplug code, where a CPU which has been offlined can online itself before being requested, which results in things going astray on the next online/offline cycle. What happens in the normal online/offline/online cycle is: CPU0 CPU3 requests boot of CPU3 pen_release = 3 flush cache line checks pen_release, reads 3 starts boot pen_release = -1 ... requests CPU3 offline ... ... dies ... checks pen_release, reads -1 requests boot of CPU3 pen_release = 3 flush cache line checks pen_release, reads 3 starts boot pen_release = -1 However, as the write of -1 of pen_release is not fully flushed back to memory, and the checking of pen_release is done with caches disabled, this allows CPU3 the opportunity to read the old value of pen_release: CPU0 CPU3 requests boot of CPU3 pen_release = 3 flush cache line checks pen_release, reads 3 starts boot pen_release = -1 ... requests CPU3 offline ... ... dies ... checks pen_release, reads 3 starts boot pen_release = -1 requests boot of CPU3 pen_release = 3 flush cache line Fix this by grouping the write of pen_release along with its cache line flushing code to ensure that any update to pen_release is always pushed out to physical memory.

2010-12-20ARM: SMP: remove smp_mpidr.hRussell King1-1/+0
With "ARM: CPU hotplug: remove bug checks in platform_cpu_die()", we now do not use hard_smp_processor_id(), we no longer need to read the hardware processor ID. Remove the include providing this function. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2010-12-20ARM: CPU hotplug: remove bug checks in platform_cpu_die()Russell King1-10/+0
platform_cpu_die() is entered from the CPU's own idle thread, which can not be migrated to other CPUs. Moreover, the 'cpu' argument comes from the thread info, which will always be the 'current' CPU. So remove this useless bug check. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2010-12-20ARM: CPU hotplug: move cpu_killed completion to core codeRussell King1-7/+1
We always need to wait for the dying CPU to reach a safe state before taking it down, irrespective of the requirements of the platform. Move the completion code into the ARM SMP hotplug code rather than having each platform re-implement this. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2010-12-20ARM: SMP: consolidate trace_hardirqs_off() into common SMP codeRussell King1-2/+0

2010-12-20ARM: SMP: consolidate the common parts of smp_prepare_cpus()Russell King1-21/+3
There is a certain amount of smp_prepare_cpus() which doesn't belong in the platform support code - that is, code which is invariant to the SMP implementation.

2010-12-20ARM: SMP: Clean up ncores sanity checksRussell King1-6/+0
scu_get_core_count() never returns zero cores, so we don't need to check and correct if ncores is zero. Tegra was missing the check against NR_CPUS, leading to a potential bitfield overflow if this becomes the case. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2010-12-20ARM: SMP: move CPU number sanity checks to smp_init_cpus()Russell King1-13/+13
