Coreboot support for atom c3000

[Tirumalesh]

Hi,

I am new to coreboot, could someone help me understand

1. Does coreboot support atom c2000 and in future c3000 once intel fsp is available?
2. Is there any limitations of intel atom support.
3. How much effort is it to port coreboot to new  board based on intel Atom

Thanks in advance.
