Thanks for the review and the welcome. The first part (infrastructure 
changes to support platform devices) has not really been commented yet. 
If this means it is already in acceptable shape, I propose to re-submit 
it separately so it can be merged ahead of the rest. Let me know if you 
would like us to generalize the use of the bus abstraction functions 
throughout the driver.

For the actual GK20A support, what worries me the most is the memory 
model, and my very incomplete understanding of how Nouveau manages 
memory doesn't help here. I hope to get some more feedback about it and 
see if we can fit somewhere before attempting broader changes.

Thanks!
Alex.
