Thanks, that helps set the stage with AMD discussions.

Comparing the blob-free versions from Intel (which are apparently signed, so according to http://www.coreboot.org/Binary_situation are at a 9000+ panic level), would it be possible to have blob-free (probably through RE) that would work (meaning does not require signed binaries) on an AMD board?

We will do what we can here. The issue is even with immense leverage, having the source released (from AMI, or AMD, (or Intel for that matter)) would undermine tremendous profit that these companies make by keeping this proprietary. So I’m leaning toward the direction that we’d have to RE the missing pieces (but could be wrong, thus the questions).
