I found the terms 'Embedded Controller' 'Northbridge' 'southbridge' 'Platform Controller Hub' 'super I-O' and I am not sure to understand the difference.
Northbridge and southbride difference is clear as it's explained on wikipedia
EC is also explained on wikipedia.
However no mention of each other is on neither page. And I have a feeling that they might be the same?
I am trying to write on an EC register and got confused by the North/southbridge notions. (note this EC is IT8570 for reference).
