I think there is no public BSP from us for that board, although we have
worked a lot with the atmel chips in the past (but usually on custom
hardware). You can basically use any BSP for a start and adapt it to
your hardware needs.

Atmel plays nicely with the mainline kernel, so please start with 3.4.x
and check how far you come.

Currently yes.

It depends on what you want to achieve by running in QEMU. As a rule of
thumb, qemu is often a good thing when it comes to system issues, but if
you care about hardware, you should run on hardware.

This is modelled in the open firmware devicetree. Your bootloader has to
know the information and put it into the right location.
