This patch lists all supported vesa mode by oprom using Function 0x4F00 (return vbe controller information). This information might be useful for user to select correct vesa mode for oprom. TEST=Enabling external pcie based graphics card on ICLRVP Case 1: with unsupported vesa mode 0x118 Now coreboot will show below msg to user to know there is a potential issue with choosen vesa mode and better users know the failure rather going to depthcharge and debug further. Calling Option ROM... ... Option ROM returned. VBE: Getting information about VESA mode 4118 VBE: Function call invalid with unsupported video mode 0x118! User to select mode from below list - Supported Video Mode list for OpRom are: 0x110 0x111 0x113 0x114 0x116 0x117 0x119 0x11a 0x165 0x166 0x121 0x122 0x123 0x124 0x145 0x146 0x175 0x176 0x1d2 0x1d4 Error: In vbe_get_mode_info function Case 2: with supported vesa mode 0x116 Calling Option ROM... ...
