It would really be nice if you could help make this target work with
the updated coreboot sources.
I would actually expect this to require only moderate effort.

1. Backport support for high tables from current code
2. Fix current code for your target
I would strongly prefer option 2.
Can you show us boot logs from your working version and from the
very latest version?
