Lean Sheng Tan has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/34159 ) Change subject: mb/intel/coffeelake_rvp: Fix display issues on CFL-H, CFL-S, WHL Intel RVP ...................................................................... mb/intel/coffeelake_rvp: Fix display issues on CFL-H, CFL-S, WHL Intel RVP This patch fixes display issues on both CFL-H & S, and WHL Intel RVP platform where display are not showing up in UEFI shell, by configuring DDi ports in device tree. This patches also fixes no eDP display observed in UEFI shell on UEFI Payload. Root cause is eDP requires minimum delay between GPIO programming and eDP initialisation, which was not sufficient during FSP initialisation which causes VBT to return error during eDP init. This issue is fixed by programming eDP GPIO's in bootblock stage and skipping FSP GPIO programming by setting 'DdiPortEdp=0' in devicetree. TEST= verified eDP display, HDMI and DP functionalities on CFL-H, CFL-S & WHL Intel RVP platforms.
