Subject[PATCH 1/2] Support for the at91sam9g20 : Atmel 400Mhz ARM 926ej-s SOC
Support for the at91sam9g20 : Atmel 400Mhz ARM 926ej-s SOC.

At91sam9g20 is an evolution of the at91sam9260 with a faster clock speed.
We created a new board for this device but based the chip support directly
on 9260 files with little updates.
Here is the chip page on Atmel website :
http://atmel.com/dyn/products/product_card.asp?part_id=4337
