[PATCH 0/4] Get kexec working on SMP omap variants

Hi all,

Here are some patches to make kexec work for SMP omaps. To test
these you need to use the latest kexec-tools.git kexec with
Russell's recent patches in "[PATCH 0/2] Simple fix to the ARM
kexec tools implementation" thread fixed for 6x. Or else you
need to use appended DTB.

I've tested these so far on 4430 duovero, omap5-uevm, and
beagle-x15.

Regards,

Tony
