I've been able to implement the 'AGESA_HOOKBEFORE_DRAM_INIT' to try to see what AGESA blob is doing and it's call 10 time before
resetting the board. Any with AGESA experience could confirm this is a normal behavior?
Anybody knows if there are any board using the IDS (Integrated Debug Services) of the AGESA? I would like to activate it to try to get more info
about what's going on...

I'm trying to use coreboot on a custom board based on the stoneyridge AMD SOC. I'm
reusing the mainboard/amd/gardenia code. We have serial console and I've been able
to trace down to 'AmdInitPost(PostParams);' called from 'src/soc/amd/common/block/pi/agesawrapper.c'
to the responsible to make the board reset. Maybe we have some hardware problem related
to the DIMM area.
Then, there is some way to get some callback, trace, etc from the AGESA blackbox code? Any
chance to use the Integrated Debug Services (IDS)? Any recommendation to solve this?
