Remove arm_machine_restart() as this function no longer does anything useful. For samsung platforms, remove the include of mach/system-reset.h and plat/system-reset.h from their respective mach/system.h headers as these just define their arch_reset functions. As a result, the s3c2410 and plat-samsung system-reset.h files are no longer referenced, so remove these files entirely.

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

When the kernel is compiled in Thumb-2 mode, this is invalid and causes the machine to hang hard when a CPU is offlined. 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).

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

* | ARM: 6635/2: Configure reference clock for Versatile Express timersPawel Moll2011-01-251-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Timers on Versatile Express mainboard are used as system clock/event sources. Driver assumes that they are clocked with 1MHz signal. Old V2M firmware apparently configured it by default, but on newer boards one can observe that "sleep 1" command takes over 30 seconds to finish, as the timers are fed with 32kHz instead... This patch performs required magic and also removes code clearing timer's control registers, as exactly the same operations are performed by the timer driver few jiffies later.
