Hi,
You need to send correct commands to firmware. Plz check
http://www.coreboot.org/AMD_IMC for a summary. Then I would say the interface
did not change much, so looking into some agesa code will tell you how to
program stuff there (there are files like imcEnv.c iirc) I need run now, plz ask
if you want more info.
Also, you will need to enable the IMC and load firmware. The agesa has some
straps override for this. You just need to place the imc.bin in cbfs on right
offset.
Thanks
Rudolf
