Good news? This is soon going to change...
Finally, AMD is now committed to support coreboot for all future products on
the roadmap starting next with support for the upcoming “Llano” APU. AMD
has come to realize that coreboot is useful in a myriad of applications and
markets, even beyond what was originally considered. Consequently, AMD plans
to continue building its support of coreboot in both features and roadmap for
the foreseeable future.
