The first reason for selecting the CPU model at compile time was a
multi-second pause if booting a single core Fusion T40R with MAX_CPUS=2.
Recent tests show the pause has disappeared, someone must have fixed it.
The second reason was me not knowing how to make a single vgabios image
work with two different PCI IDs. Many thanks to Martin Roth for educating
me! Quote:
"The way to make coreboot use the same vbios for different video device IDs
is through the map_oprom_vendev function. In family 14 it's in
northbridge/amd/agesa/family14/amdfam14_conf.c You would name your video
bios 1002,9802 in the config and all the other device/vendor IDs for the
family 14h processors will fall through the initial check for the video
bios and will get remapped to use that vbios. This only works if you're
initializing the vbios inside coreboot. I don't know if you're using
SeaBios as a payload, but if you are you can add the vbios to cbfs as
vgaroms/vbios.rom and the rom will always be initialized."
I'd like to add the vgabios is added as type 'optionrom' when Coreboot make
adds it, however to work with SeaBios it has to be added manually with
cbfstool and with type 'raw', or it will hang.

Step 2: change the Persimmon code to adapt it to the new board's hardware.
The FrontRunner-AF is a PC/104+ form factor embedded board:
- AMD Fusion G-T56N (1.65 GHz dual core) or T40R (1 GHz single core) APU
- DDR3 SO-DIMM socket (1.5 or 1.35V)
- VGA and LVDS (via Analogix ANX3110)
- AMD A55E (Hudson-E1) southbridge
- 6x USB 2.0
- 1x SATA, 1x CFast socket
- HD Audio (via Realtek ALC886)
- PCI and ISA (via ITE IT8888)
- NEC uPD78F0532 microcontroller on I2C ("SEMA")
- Intel I210 GbE (on APU PCIe x1)
- SMSC SCH3112 SIO
- PS/2
- 2x RS232/485
- 2x SST 25VF032B (SO8, soldered) 4 MB SPI flash (BIOS and failsafe BIOS)

Step 1: copy all files unmodified from Persimmon. This makes it much
easier later to see how the two boards actually and deliberately differ
when porting bugfixes from one to the other. Git's copy detection is
imperfect (and slow).
