Patch Set 1:
There is thorough functionality in libgfxinit. If it's only about fetching the EDID, we'd just have to export one more function. Let me know if you want to give it a try.
Heh, this "just have to export" turned into a series of patches. The library was only included into the build when configured to use it for actual gfxinit. But I got something to compile, untested though: CB:31458. It includes an update to the submodule pointer with wip changes to libgfxinit, so that requires a manual fetch there: cd 3rdparty/libgfxinit git fetch https://review.coreboot.org/libgfxinit refs/changes/54/31454/3
Oh, and I realize now, it's not hooked up for all sup- ported platforms yet.
I was distracted with other fires but I got a chance to try this today and it was functional and I was able to read the EDID.
I need to figure out how to integrate this into the chromium build to use it, looking into the feasibility of that now...
