Good news for kernel hackers, and especially coreboot developers like me: AMD has released the chipset documentation for the RS780 chipset, including the BIOS Developer's Guide. And these documents are being released freely and openly to the public, no NDAs required, which is great!
The coreboot community, which includes government organizations, corporations, research labs and individuals from around the world, is very excited to expand on our existing and decade-long collaboration with AMD. This collaboration has, over the years, resulted in the inclusion of coreboot into everything from some of the largest AMD-based supercomputers in the world to some of the smallest embedded systems.
Together with the recent SB700/SB710/SB750 documentation release, the Developer Guide release for the RS780 family of Integrated Chipset/Graphics Processors enables the coreboot community to support any board with AMD chipsets out there, from embedded to enthusiast desktop and high-end server boards.
This new release once again demonstrates AMD's commitment to open standards and software that provides an improved user experience and Total Cost of Ownership for users in every walk of life. One cornerstone of this openness is the availability of documentation without NDA, enabling everyone to contribute.
Coreboot is open source, so every interested developer or user can modify, tweak and extend it to their heart's content.
An additional benefit of this documentation release is flashrom support for all AMD chipsets which enables users to reflash their BIOS/firmware/coreboot from within Linux and *BSD without rebooting.
Coreboot code for the SB700 and 780 chipset family is already being worked on by Zheng Bao at AMD in his spare time and the coreboot community is happy to work with him on finishing and integrating the code into the official coreboot codebase.
We'd like to thank Sharon Troia at AMD for making these documentation releases possible.

Since the "World's First Motherboard Using LinuxBIOS Released" hype at the beginning of this year (which was incorrect btw; it was not the first supported desktop board, there were many others before), LinuxBIOS hasn't been in the news very much. That doesn't mean that there was no progress, however. We've been working hard behind the scenes to improve the LinuxBIOS code, add support for new chipsets and boards, and advance the upcoming next-generation LinuxBIOSv3 version which will brings lots of great improvements in various areas.
Here's a random collection of stuff that happened in the last few months.
Most work will probably go into LinuxBIOSv3 in the future, in order to make it suitable for productive use.
Of course, work on new chipsets and boards will continue, too. For example the VIA CN700 chipset (plus Jetway J7F2WE board using it) is being worked on right now, probably also several others I don't know about.
If you're interesting in trying out LinuxBIOS, please check the list of supported motherboards. If your board is not listed there, but the chipset is already supported we can probably add support for your board relatively easy with some testing help from you.
An (incomplete) list of good candidate boards for future support is available in the wiki.
We're very grateful for the many contributors who have helped us with testing and fixing existing code, or who even contributed code for new chipsets and motherboards. Thanks a lot!
Many thanks especially to all hardware vendors who have been supporting us or even actively contributed by submitting code for their chipsets or boards (recently or in the past), including AMD, SiS, VIA, MSI, Tyan, Artec Group, and many others. Your efforts are very appreciated. Thanks!
