cover ARM: SMP initialization consolidation

Quoted 52 lines · Rob Herring

From: Rob Herring<[email protected]>
In order to avoid duplicating the same platform code yet again for a new platform, this series consolidates platforms using similar SMP startup code to a common implementation. A new kconfig entry SMP_COMMON_PEN is added for platforms using the common pen functions.
OMAP uses a h/w mechansism for its pen, but it seems like it could use the same mechansism.

ARM: move Versatile SMP pen code to common location
ARM: ux500: convert to use common secondary pen code
ARM: msm: use common secondary pen code
ARM: add common scu_init_cpus
ARM: omap: use common scu_init_cpus
ARM: realview: use common scu_init_cpus
ARM: vexpress: use common scu_init_cpus
ARM: ux500: use common scu_init_cpus
ARM: shmobile: use common scu_init_cpus
ARM: move set_cpu_present calls to common smp code

I only have a Versatile Express to test on, so any Tested-by's would be appreciated.

I don't seem to be able to find the actual patch messages themselves, only this message. Do you have a reference on an archive somewhere?

Thanks,
David
