Netbsd /avr32 update.

[Tomas Niño Kehoe <tomasninokehoe%gmail.com@localhost>]

Hi everyone,

Today I presented my NetBSD/avr32 port at eurobsdcon in Malta.

This came out ok, and I received great feedback from those present. I can't
remember all the names right now, I do remember Adrian Steinman and Valeriy
Ushakov being there.

NetBSD/avr32 is now capable of executing a shell, which is a static Linux
busybox, due to reasons explained during the presentation (i.e the
development was focused on the kernel)

The next step, besides continuing / fixing the actual port is to start
working on the toolchain. Particularly an llvm backend for NetBSD/avr32 seems
the way to go.

As usual code is availabe at
https://github.com/Tommmster/netbsd-avr32

Starting kernel at 90000000 (params at 11fc0040)...
