2010-04-26	sh: CPU hotplug support for SH-X3 SMP.	Paul Mundt
	This wires up CPU hotplug for SH-X3 SMP CPUs. Presently only secondary cores can be hotplugged given that the boot CPU has to contend with the broadcast timer. When real local timers are implemented this restriction can be lifted. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-26	sh: Make sure all SH-X3 cores are populated in the present CPU map.	Paul Mundt
	This iterates over the maximum number of CPUs we plan to support and makes sure they're all set in the present CPU map. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-21	sh: Move platform smp ops in to their own structure.	Paul Mundt
	This cribs the MIPS plat_smp_ops approach for wrapping up the platform ops. This will allow for mixing and matching different ops on the same platform in the future. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-15	sh: Disable IRQ balancing for timer and IPI IRQs.	Paul Mundt
	Make sure that the timer IRQs and IPIs aren't enabled for IRQ balancing. IPIs are disabled as a result of being percpu while the timers simply disable balancing outright. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-01-15	sh: Fix up the secondary CPU entry point for 32bit mode.	Paul Mundt
	Presently the secondary CPU entry point is only aimed at 29bit phys mode, causing it to point to a stray virtual address in 32bit mode. Fix it up after consulting with our shiny new __in_29bit_mode(). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-10-16	sh: Force boot CPU in to light sleep mode for SH-X3 SMP.	Paul Mundt
	All of the secondary CPUs are forced in to light sleep mode, but we were missing the same initialization for the boot CPU. This resulted in inconsistent sleep modes depending on which CPU we were on, confusing the idle loop when not polling. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-08-19	sh: Fix up clockevents broadcasting.	Paul Mundt
	This fixes up the clockevents broadcasting code as detailed in commit ee348d5a1d810bc9958cabb7c27302aab235d36e ("[ARM] realview: fix broadcast tick support"). This saves us from having to do strange ordering things with the broadcast clockevent device, relying on the rating instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-06-14	cpumask: Use accessors for cpu_*_mask: sh	Rusty Russell
	Use the accessors rather than frobbing bits directly (the new versions are const). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Mike Travis <travis@sgi.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-08	sh: smp: shove a cpu_relax() in the plat_start_cpu() busy loop.	Paul Mundt
	Without this, certain versions of GCC will happily optimize the entire loop out. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-09-08	sh: smp: Hook in to the generic IPI handler for SH-X3 SMP.	Paul Mundt
	Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-09-21	sh: Initial SH-X3 SMP support.	Paul Mundt
	This adds basic support for SH-X3 SMP (4 CPUs). More IPI and cache debugging is necessary, mostly interfacing the d-cache coherency and the I-cache broadcast invalidates. Only for testing at present! Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
