Has the upstream Seaboard (or Harmony) build ever been able to boot a kernel? I've never tried it, as I thought it was too incomplete for that yet (i.e. needs more drivers/periphs init'd first).
You can file a bug if you wish as a placeholder. I'm not sure what's missing (if it's not a regression) - bootargs for a kernel? _ATAG config items? If they were there & were taken out in a particular patch series, I'd like to see the person responsible for that be tasked w/replacing them (edited, if need be, for current state such as WB/LP0 vec, usb/mmc boot, etc.).
