ATI chipset based maintboards

[Mikhail Savchenko]

Hi, can you tell me what kind of technology documentations should our
company (we are AMD partner) get from AMD/ATI to be able add support of ATI
chipsets to coreboot?

Data books with all the information on the chipset register 
descriptions, register settings and programming steps.

Depends on the chipset. Some information (the RS690 Register Reference
Guide) is public, some information may be difficult to get (SB600).
Basically, the documentation you want are called "Register Reference
Manual" or "BIOS Writer's Guide" or something similar.

Regards,

Also, not to discourage, but keep in mind that if your company is using
coreboot in a product, your source code needs to be made available to the
public (a condition of the GPL). You should probably include this
information with your requests, and make sure that AMD is okay with it. I
can't imagine any problems, AMD has been very good to us, but best to cover
yourself ;)

You need the data sheets for (northbridge and) southbridge, as well as 
possibly schematics of the board used. Not sure if there is a specific 
"Bios Writers Guide" for the ATI chipset you are using. There is a "Bios 
and Kernel Developers Guide" for AMD64 from AMD which is an excellent 
document, but it covers (mostly) AMD chipsets only
