Cover letter [PATCH 00/10] 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.

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