AMD just released the following docs we need for SB700/SB710/SB750 coreboot support:
* AMD SB700/710/750 Register Reference Guide * AMD SB700/710/750 BIOS Developer’s Guide * AMD SB700/710/750 Register Programming Requirements * AMD SB710 Databook
Links to all data sheets are at http://www.coreboot.org/Datasheets#AMD_SB700.2FSB710.2FSB750
This is a great step towards supporting current RS780/SB700 family systems.
Immediate benefits of this doc release are: - We can implement SB700/SB710/SB750 support without NDA. - We can study the embedded controller environment and the SuperI/O functionality in some SB7x0 southbridges.
Future benefits are: - We can support 690/SB700 boards once the SB700 code is done. - We can test SB700 code in 690/SB700 boards and make sure it works perfectly before we start working on RS780 code. - We have 50% of the docs we need for almost all boards with AMD chipset on sale today.
What can we do next? - Implement SB700 code. - RS690/SB700 boards do not exist. However, it seems that RS740 is RS690 with a modified graphics core, so RS740/SB700 boards are the best targets we can pick.
List of possible targets with RS740/SB700: - ECS Elitegroup A740GM-M (89-206-V15102) http://www.ecs.com.tw/ECSWebSite/Products/ProductsDetail.aspx?detailid=864&a...

Thanks to AMD for releasing these docs!
