2014-06-17ARM: shmobile: Move common.hMagnus Damm1-1/+1
Change location for common.h so it can be used as #include "common.h" instead of the old style #include <mach/common.h>.

2013-09-30ARM: shmobile: Remove shmobile_smp_scu_boot_secondary()Magnus Damm1-8/+0
Remove shmobile_smp_scu_boot_secondary() since it is no longer used. CPU boot vector setup is instead handled by CPU notifiers. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2013-09-30ARM: shmobile: Add CPU notifier based SCU boot vector codeMagnus Damm1-0/+24
Add CPU notifiers for the shared mach-shmobile SCU code to allow removal of the shared SCU boot_secondary code. Regarding notifiers, at CPU_UP_PREPARE time the SMP boot vector is initialized so secondary CPU cores can boot.

2013-08-06ARM: shmobile: Per-CPU SMP boot / sleep code for SCU SoCsMagnus Damm1-6/+11
Hook in the per-CPU boot and sleep code in the shared mach-shmobile SCU code. CPUs may be kept in the asm routine until ->boot_secondary() when the per-CPU boot vector is installed. At the end of ->die() the asm sleep routine is invoked. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2013-08-06ARM: shmobile: Add shared SCU CPU Hotplug codeMagnus Damm1-0/+45
Add CPU Hotplug functions for SCU equipped mach-shmobile SoCs. The functions shmobile_smp_scu_cpu_die() together with shmobile_smp_scu_cpu_kill() perform basic shutdown and allows checking of shutdown status. These are written to work together with SMP boot code in headsmp-scu.S. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2013-08-06ARM: shmobile: Introduce shared SCU SMP boot codeMagnus Damm1-0/+31
Add SMP boot functions for SCU equipped mach-shmobile SoCs. At this point shmobile_smp_scu_prepare_cpus() controls the SCU and installs boot fn and arg, while shmobile_smp_scu_boot_secondary() currently does nothing. In the future the boot function and arg install code will be reworked, so the empty function is ground work for that.
