Sure, I can.

Tunnel Creek has one GPU integrated, but on my Crown Bay board, the
output siginal is routed to LVDS to be connected to an external LCD,
which I don't have for now. There is no public datasheet describing
the details about the integrated GPU, neither did I found a legacy
video ROM supporting that. There seems to be a UEFI native graphics
driver from Intel, but that means I will need study that and write a
U-Boot native graphics driver, which needs some time. Maybe supporting
PCIe based graphics card is an option, and I will find some time to
try that.

Regards,
Bin
