From: Fabio Estevam fabio.estevam@freescale.com

SolidRun has designed the Hummingboard board based on mx6q/dl/solo.

Add the initial support for the mx6 solo variant.

More information about this hardware can be found at: http://imx.solid-run.com/wiki/index.php?title=Carrier-One_Hardware

(Carrier-One was the previous name of Hummingboard).

Based on the work from Jon Nettleton jon.nettleton@gmail.com.
