I don't have it working, but I would suggest to try either the last
commit which touches the mainboard files, or the last commit which
touches the platform component files (northbridge and southbridge).

git log with appropriate parameters makes it easy to find these
commits from the history.

It looks like raminit worked, but the fact that executing from RAM
does *not* work speaks against that.

Which toolchain did you use when building? Please run

make crossgcc

in the top-level coreboot directory to build a known-good toolchain
if you haven't already. After running that command, you can verify
that the toolchain will be used the next time you compile coreboot:

cat .xcompile

should show various paths into a subdirectory with an xgcc/ path
component.
