Subject: Boot cpu != cpu 0 ?

Hi
How hard it could be to build a system on multi-core arm hardware, that has
linux SMP running in cores other than 0th ?
Say, if bootloader starts kernel on hardware core 1, will kernel be able to
work (and use cores 1,2,3 on 4-core hardware) after some tweaking?
Or "boot cpu" concept is uncouplable from "hardware core 0" by
architecture?
I'm asking because there is a project with a strict requerement to have
core 0 reserved and not touched by linux, and I need to understand how
realistic it is.
Thanks for any hints.
Nikita
