[coreboot] VGA doesn't work on Mohon Peak

[Kuzmichev Viktor]

Hello.

Sorry it took me so long to reply.

So, I tried the suggested setup and it didn't work. Here is my CBFS:
$ ./build/cbfstool build/coreboot.rom print
coreboot.rom: 8192 kB, bootblocksize 1024, romsize 8388608, offset 0x600000
alignment: 64 bytes, architecture: x86

fsp.bin                        0x77ffc0   fsp          372736
(empty)                        0x7db000   null         150424

And the output log with SeaBIOS debug level set to 8 is in the attachment.
