Dear coreboot folks,
I noticed commit 5d1494adda44 (mb/system76/tgl: Update VBTs to version
250) [1]:
> mb/system76/tgl: Update VBTs to version 250
>
> Commit 4c7e97b26a34 ("Update fsp submodule to upstream master branch")
> included an update to the VBT from 240 to 250, breaking parsing of
> existing VBTs.
>
> After that commit, the VBT was parsed as (from gaze16-3060-b):
>
> [DEBUG] PCI: 00:02.0 init

Updating the submodule pointer of 3rdparty/fsp brings in commit
849ce8261bb0 (Tiger Lake FSP A.0.7E.70) with no commit message body. The

Vladimir (φ-coder) also published the tool intelvbtupgrader [2] to
address this problem.
I would have assumed that FSP versions would be backwards compatible. I
attache the output of `intel_vbt_decode` of both VBT files.
Does somebody have more insight?
Kind regards,
Paul
