http://www.telit.com

Based on at91sam9260ek board support.

Signed-off-by: Fabio Porcedda <fabio.porcedda at gmail.com>
---
v3:
 - add dfu support
 - init.c: reduced bootstrap size
 - init.c: moved istructions from evk_add_device_nand function to the struct
 - init.c: remove blank line
 - renamed to telit-evk-pro3

v2:
 - init.c: remove 9260ek and g20ek references
 - init.c: rename ek_ -> evk_
 - init.c: cleanup headers
 - init.c: use clock framework
 - init.c: remove function ek_set_board_type
 - init.c: remove bus_width_16 initialization
