From 22ee647380c42f44528f99b7c1b423725e542102 Mon Sep 17 00:00:00 2001 From: Sedji Gaouaou Date: Thu, 9 Jul 2009 10:16:29 +0200 Subject: at91: Introduction of at91sam9g45 SOC. AT91sam9g45 series is an ARM 926ej-s SOC family clocked at 400/133MHz. It embeds USB high speed host and device, LCD, DDR2 RAM, and a full set of peripherals. The first board that embeds at91sam9g45 chip is the AT91SAM9G45-EKES. On the board you can find 2 USART, USB high speed, a 480*272 LG lcd, ethernet, gpio/joystick/buttons.
