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.
