I'm working on a system which some decently advanced functionality booting a linux 3.14 kernel on an ARM. Currently I'm getting around ~5 seconds, from turning the power on to having the system fully loaded and ready. I could possibly get it lower but it meets spec and any additional shaving off would probably require plenty of work while sacrificing debug-ability etc. so for now I'm fine where it is :)
