[Arm-netbook] Development environment for the A20 card

Sorry if this has come up before and I missed it.

Is there a recommended software development environment for the A20 card that people can use to experiment with in place of the real thing? I'm thinking of something as basic as a set of configuration options for qemu.

I know the Cubieboard or Cubietruck has been mentioned before in the context of whether software will be portable to the card. I just wondered if there's any more concrete information about using virtual environments for those systems in the context of the A20 card.
