AMD Publishes New SB Register, Programming Docs
While most of the time getting new documentation out of AMD is for their ATI graphics processors, today they have pushed out four documents that amount to several hundred pages of information covering their latest Southbridges. The AMD SB700/710/750 chipsets are now well documented in these NDA-free programming guides that also cover the registers for this hardware.
Over at AMD Developer Central is the AMD SB700/710/750 Register Reference Guide, AMD SB700/710/750 BIOS Developer’s Guide, AMD SB700/710/750 Register Programming Requirements, and lastly is the AMD SB710 Databook.
Sure, programming guides and register descriptions for a southbridge is not nearly as exciting as for the latest ATI GPU, but this information is what the CoreBoot developers (the same ones working on Flashrom) have been after for a while. As can be seen from the AMD Developer Forums there have been open-source developers after this hardware documentation for a number of months.
