Dear list, thank you for the help with cross-compiling for ppc64 so far! It is important but I overjumped enthusiastically the OF basics :-)
I read many webpages, hints and maybe old sites etc and solved many things. But is there a "beginners how-to" somewhere? What I would find most usefull:
1) Best source-code to use? There is a version-1.1.zip, a svn repo and a git repo.
2) The names are also a bit confusing when you see it first. I know about the IEEE standard and a few things about the history (from wikipedia), but if you for example visit the website and click on the "openfirmware" link, the you see a page with "OpenBIOS" heading. So even if one knows about history, there is confusion about actual used names.
3) How is the device-tree given to OF? And how does OF handle it over to a linux kernel?
4) Minimal prerequisites on a new hardware, so that OF is able to run? E.g. which type of RAM does it need? Does it need a stack or .text segment or other things to run (like c-code)? ...
If these points would be clarified, the it would be much easier for new people to help with e.g. additional targets or maybe new architectures.
Thanks for your time! Greetings, Michael
