There have likewise been some API updates, so we refactor to use the consolidated smp_prepare_cpus(). Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Add SMP support for ag5evm and the sh73a0 processor. Onlining and offlining works well, but at this point offlined processor cores are not put into sleep mode. There is no spinlock for syncing the secondary core with the first one in this implementation. The code instead relies on the cpu_online() check in __cpu_up().

Add SMP base support for R-Mobile / SH-Mobile processors. This patch contains all base code to support CONFIG_SMP regardless of ARCH_SHMOBILE processor type. Both local timer and CPU hotplug are supported, but no processor specific code is included. At this point only the default behavior is in place, so a single core will always be used even though CONFIG_SMP is enabled on multicore systems. The SMP Kconfig entry for arch/arm/Kconfig is excluded from this patch to simplify merging. Signed-off-by: NMagnus Damm <damm@opensource.se> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>
