It's essential to have CONFIG_ASPEED_DP=y in _U-Boot_ config for DP
output to work. Because for whatever odd reason "The MCU FW controling
ASPEED DP is loaded by BMC boot loader."[0] And if it's not loaded
Linux just silently fails.
For Linux DT you might need to check that &video and &gfx are enabled.
With this the host system should see a video card on PCIe bus and if
you followed the reference schematics the image should appear on
AST2600 DP output.
