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.
