Gumstix / PXA270 support

[Magnus Eriksson <magetoo%fastmail.fm@localhost>]

I am about to get involved in a small project that will likely use a 
Gumstix board as a major component; and it will be one of the Vertex 
boards, which are PXA270-based.
I see that PXA255 is supported by evbarm now, but not PXA270.  How 
complicated would it be to add support for the '270?  I am not up to the 
task of doing any major development work, but minor tweaks or simply 
testing somebody elses code should be fine I think.

(Our project is not dependent on getting NetBSD running, by the way - it 
would just be nice to be able to add support for the boards.)
