Thu Dec 5 08:28:06 EST 2013
From: Eric Bénard <eric at eukrea.com>
The following devices/functionalities were tested:
* Main UART.
* Ethernet0.
* Ethernet1.
* SD.
* USB host.
* USB otg.
* Display(and its backlight).
* Touchscreen.
* Audio.
* nand.
* i2c and the pcf8563 device.
* The gpio buttons.
* The gpio leds.
* Watchdog
