Hi all,
I drafted a quick wikipage to explain how to port EDK2 (UEFI Open Source implementation) on a new ARM Platform : http://sourceforge.net/apps/mediawiki/tianocore/index.php?title=ArmPlatformP kg I am aware this wikipage could require some EDK2 knowledge but I will try to fill these gaps in the future by creating or referring to wikipages that explains some of the key EDK2 concepts.
Feel free to directly send me an email if you want more explanations about a specific concept. That would help to define priorities.
