From: Fabio Estevam <fabio.estevam@freescale.com>

Add initial support for Wandboard dual lite.

Wandboard is a development board that has two variants: one version based
on mx6 dual lite and another one based on mx6 solo.

For details on the features of Wandboard, please refer to:
http://www.wandboard.org/

This applies on top of Eric's series for adding nitrogen6x boards support.

Thanks!

Can we please use get_ram_size() to verify / test the actual RAM size?

Is this really needed?

What is the  "1u *" needed for?
