Cherry picking did not worked for me. I cloned coreboot today on an new
linux installation.
So i did additional:
$ cd 3rdparty/libgfxinit/
$ git checkout master
$ cd -
$ git add 3rdparty/libgfxinit/
Then i build the buildroot and the coreboot image.
I think i should have the patch (and some other things that was merged
in between) now inside the image. But i still dont have any seabios
output on the screen. I am using seabios master.
Then i tried out linear (high resolution) framebuffer.
I got that when building:
...

Hello H42,
there is an issue with upscaling VGA text mode on G4x that is about to
be fixed [1]. Looking at your logs again, you are likely also affected
(scaling 640x400 to 1920x1080). The fix is already merged to the lib-
gfxinit repository, but the submodule pointer in coreboot is not
updated
yet. You can try the fix as follows:
$ cd 3rdparty/libgfxinit/
$ git fetch https://review.coreboot.org/libgfxinit
refs/changes/55/28255/3
$ git cherry-pick FETCH_HEAD
$ cd -
$ git add 3rdparty/libgfxinit/
Then rebuild your coreboot.
Hope that fixes your issue. Another workaround would be to use a linear
framebuffer instead of text mode (CONFIG_GENERIC_LINEAR_FRAMEBUFFER).
