| | * | | | | ARM: vexpress: Use FDT data in platform SMP callsPawel Moll2012-02-242-2/+155
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Scan flatten device looking for A5/A9 SCU node and initialize it using base address in "reg" property. If nothing is found, assume that there is no special SCU initialization required and initialize CPUs basing on numbers of "cpu" type devices in "cpus" node of the Device Tree. All this happens only if the board was booted with FDT, otherwise ct_desc callbacks are used. Signed-off-by: Pawel Moll <pawel.moll@arm.com>

* | ARM: 7293/1: logical_cpu_map: decouple CPU mapping from SMPWill Deacon2012-01-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It turns out that the logical CPU mapping is useful even when !CONFIG_SMP for manipulation of devices like interrupt and power controllers when running a UP kernel on a CPU other than 0. This can happen when kexecing a UP image from an SMP kernel. In the future, multi-cluster systems running AMP configurations will require something similar for mapping cluster IDs, so it makes sense to decouple this logic in preparation for this support.

Boards/SoCs which cannot reliably operate without the L2 cache controller support will need to select CACHE_L2X0 directly from their own Kconfigs instead.

Using the wfi macro (which uses the appropriate assembler mnemonic) causes the correct instruction to be emitted in either case. As a consequence of this change, an apparently vestigial "cc" clobber is dropped from the asm (the macro uses "memory" only).

| * | | | ARM: 7022/1: allow to detect conflicting zreladdrsSascha Hauer2011-10-171-1/+1
| | |/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Boards used to specify zreladdr in their Makefile.boot with zreladdr-y := x, so conflicting zreladdrs were silently overwritten. This patch changes this to zreladdr-y += x, so that we end up with multiple words in zreladdr in such a case. We can detect this later and complain if necessary.

| |_|/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | Rather than clipping the number of CPUs using the compile-time NR_CPUS constant, use the runtime nr_cpu_ids value instead. This allows the nr_cpus command line option to work as expected. Cc: <stable@kernel.org> Reported-by: Mark Salter <msalter@redhat.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* | ARM: 7003/1: vexpress: Add clock definition for the SP805.Nick Bowler2011-08-241-0/+7
|/ | | | | | | | | | | | | | | | | It seems that an entry for the SP805 watchdog in the table of clocks was missing. This results in the sp805_wdt driver rejecting the device with the following errors: sp805-wdt mb:wdt: Clock not found sp805-wdt mb:wdt: Probe Failed!!! sp805-wdt: probe of mb:wdt failed with error -2 While not obviously stated in the hardware docs, the onboard SP810's "REFCLK" is connected to a 32.768KHz crystal, and this drives the watchdog. Add a struct clk and corresponding lookup entry for it. Signed-off-by: Nick Bowler <nbowler@elliptictech.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| * ARM: 6993/1: platsmp: Allow secondary cpu hotplug with maxcpus=1Stephen Boyd2011-07-071-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If an ARM system has multiple cpus in the same socket and the kernel is booted with maxcpus=1, secondary cpus are possible but not present due to how platform_smp_prepare_cpus() is called. Since most typical ARM processors don't actually support physical hotplug, initialize the present map to be equal to the possible map in generic ARM SMP code. Also, always call platform_smp_prepare_cpus() as long as max_cpus is non-zero (0 means no SMP) to allow platform code to do any SMP setup. After applying this patch it's possible to boot an ARM system with maxcpus=1 on the command line and then hotplug in secondary cpus via sysfs. This is more in line with how x86 does things.
