Yes, serial/vidconsole (in that order) is the default for quite all defconfigs in u-boot.
I know where to hack/change that in u-boot but I also think that a massive u-boot hack is not what we want.
U-boot hands over to the dw- linux driver(which contains inno hdmi) in the dts-source and we fail to handle the dts/driver.
while I also think the GOP nevertheless  should persist visible for bsd.
Normally I would say that they don`t expose the frame buffer address by default, but then why does it work on RK3399 , puuuhh..
Also don`t know if my motivation for looking further is big enough :-) 
but thanks to point to the GOP-issue and vidconsole stuff,
