log when HDMI and eDP are connected.

HW : Intel Braswell N3000/N3710/J3710
FW : coreboot+FSP MR2

Linux drivers (latest taken from 01.org website) are not detecting connected
displays correctly.
The same linux with kernel option "nomodeset" boots properly... but graphics HW
acceleration is not working.
1)
When LFP display is connected on eDP port (port B) - all seems to work fine -
display is working, graphics drive is also fine.
     ---> however - a second display connected on port C (HDMI) is not even
detected.
2)
When LFP display is not connected - HDMI is actvie at boot time, by starting
from kernel driver - display is black and not active.  HDMI display device is
not detected.

Is this a known problem ???
What's the fix ?

The same HW/FW works fine with Windows 10 OS - no matter what's display
configuratuion.

Thanks,
Marek.
