coreboot-kgpe-d16/src/mainboard/amd/inagua/BiosCallOuts.c
Frank Vibrans 69da1b676c Add IBASE DB-FT1 and AMD Inagua motherboards. Patch 8 of 8. 
This code provides support for IBASE Technology DB-FT1 (AMD code name Persimmon) and AMD Inagua platforms. It is dependent on all other patches in this set.
