We now seem to have a chip keyword, in addition to config, device, 
driver and object keywords. We have a device_operations structure, a 
cpu_device_id structure and a cpu_driver structure as well as a 
pci_driver structure. The cpu tree has been reorganized to include 
vendor directories as well as architecture directories. We now seem to 
have a drivers directory tree.

Can someone please provide the following information:
1. What does each keyword actually do now?
2. How do the keywords relate to the data structures?
3. What files are now auto generated, and how is everything linked 
together?

4. What keywords/data structures are actually needed, and by which 
devices?

5. How/where are the data structures used?
6. What is the rationale behind the reorganization of the cpu tree, and 
how is it supposed to work?

7. What is the purpose of the drivers tree, how do drivers differ from 
devices, and why is the console not included?

The configuration process now seems so complicated that  I can't see 
how we could expect someone to port to a new board without some basic 
description of how everything is supposed to work. I have a major 
vendor interested in doing this, but at the moment I can't offer them 
any help.
