the following patch was just integrated into master: commit 53072d869ad9234781b5a479dfcc9a9288723da6 Author: Alexandru Gagniuc mr.nuke.me@gmail.com Date: Sat Apr 12 21:57:18 2014 -0500
cpu/amd/agesa/family15tn: Add initial support for SMM mode
This is the minimal setup needed to be able to execute SMI handlers. Only support for ASEG handlers is added, which should be sufficient for Trinity (up to 4 cores).
There are a few hacks which need to be introduced in generic code in order to make this work properly, but these hacks are self-contained. They are a not a result of any special needs of this CPU, but rather from a poorly designed infrastructure. Comments are added to explain how such code could be refactored in the future.
