Coreboot declares a complete documentation of some chips by: http://www.coreboot.org/Datasheets and particularly 82815E by: http://www.coreboot.org/Datasheets#Intel_82801BA.2FBAM_.28ICH2.29
Where is the documentation for integrated graphics controller of this chip? Only the explanation of some configuration registers are available.
Why Coreboot site maintainers do not clearly express that the necessary documentation for BIOS developing is not available? Even the open documents you have added in Data-sheet section are not complete.

It is publicly available, try googling "82815 PRM" or "Intel 815 programmers reference manual"

Watch your tongue, there is a huge difference "open documents" and public documents. The "coreboot site maintainers" which includes many people with wiki access, don't have the time to run around collecting 50 million documents floating around the web, especially chipsets that are not even supported by coreboot yet. Google is your friend.
FYI: You refer to the i815E Northbridge and link to the i82801BA ICH2 southbridge... two completely different things... are you sure you know what your doing???

Is this an Intel chip? Why don't you ask Intel?

Please, stop trolling, it is really tiresome. We explained this especially to you before, that getting documentation for BIOS development is hard, and especially hard with Intel systems. If you don't want to listen, or don't want to learn, please just go away.

How do you know that it is complete? I doubt that we have (even links to) complete documentation for anything besides superio chips.

It may be available from the manufacturer, Intel. Please talk to them. If you can acquire documentation and the permission to redistribute, then more information is of course very welcome on the datasheets web page.

Because that is already immediately obvious for someone who looks at the documentation that *is* available, or for someone with experience from PC firmware development, or for someone who starts reading the coreboot source code and tries to look up what the meaning of the code is, or for someone who gets told about this fact e.g. via email.
I'm sorry that none of this is sufficient for you.
