Boot cpu != cpu 0 ?

[Nikita V. Youshchenko]

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
