  To: barebox, marek.belisko

This work is mainly based on a9m2440 board implementation
from Juergen Beisert <jbe@pengutronix.de>. Functionality
was tested only running barebox from ram. Loading to flash
and booting will not work because missing lowlevel_init
functionality (lack of jtag debugger on my side ;)).
