[ARM] 5130/4: Support for the at91sam9g20
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 wabsite:
