mainboard/amd: add support for F2950 system board

Hardware / Coreboot - Andrey Korolyov [xdel.ru] - 17 July 2016 09:50 UTC

F2950 SBC, also known as TONK 1201/TONK 1202, was originally produced as a Centerm F2950 using DB800 reference design. Common configuration does include a 600 MHz GeodeLX CPU underclocked to 500 or 400 MHz, 128 or 512 MiB of RAM in the single SODIMM slot and 128 or 512 MB IDE DOM. The board does have three USB 2.0 ports (none of them possessing debug capabilities), PS/2, VGA, Geode audio in/out and the serial port.

EEPROM needs to be soldered out and flashed externally at the time of this message because flashrom would neither be able to dump BIOS correctly while running vendor BIOS nor write flash contents.

All peripherals were tested against Linux 3.16 and seem to work flawlessly. At the moment of this commit coreboot does not pass PCI_COMMAND_IO from the configuration space to SeaBIOS, thereby preventing VGA OPROM from being executed. This would be fixed in the SeaBIOS itself or in a subsequent commit. As a workaround, user may put VGA OPROM to vgaroms/seavgabios.bin in CBFS.
