I forget the u-boot specifics here, but if you boot over networking, for example, does that eventually end up calling bootm or would Hyp mode not be entered in this case? I'm only raising this issue because it's important to minimize the hoops and efforts for booting in Hyp mode, since it's harmless to do so regardless of the linux kernel we're booting.
