[Intel-gfx] Tizen IVI EFI 3.0 graphics failure with FSP/OTM on Bayley Bay

[Wang, Stephanie]

Jesse, hey
I work for ISG FSP/OTM boot loader team under Khadker Islam. I've recently run into an issue that blocks FSP/OTM from supporting Tizen IVI 3.0 running Bay Trail B3 silicon on Bayley Bay board.
Log file with the failure is attached. The failure is very consistent, happens every time with Bay Trail B3 silicon running FSP/OTM boot loader. The boot image was generated from Tizen IVI 3.0 EFI image posted at http://download.tizen.org/releases/milestone/tizen/ivi/latest/images/ivi-release-efi-i586/. The original image from the sever booted with EFI BIOS on the same board. Our FSP/OTM is legacy boot loader without EFI support. Failure seems to be with the graphics driver. The messages from the failure log file are shown on both serial console and local console via VGA. I need some help to understand if the driver under efi OS only works with efi BIOS? Does it need some efi run time services from the BIOS? Or does it need certain POST set up from the BIOS? Also, is there a legacy version of Tizen IVI 3.0 ? if yes, where do I get this? Any help will be greatly appreciated!
Stephanie
