From df486b1fa3f750b153eac7daa0b3bf1f594e5098 Mon Sep 17 00:00:00 2001 From: Nicolas Ferre Date: Sun, 22 Mar 2009 14:48:16 +0100 Subject: at91: Support for the at91sam9g20 : Atmel 400Mhz ARM 926ej-s SOC. AT91sam9g20 is an evolution of the at91sam9260 with a faster clock speed. The AT91SAM9G20-EK board is an updated revision of the AT91SAM9260-EK board. It is essentially the same, with a few minor differences.
