From 2dc851e3b0f07a56f83060f13882ff4b62cf5112 Mon Sep 17 00:00:00 2001 From: Albin Tonnerre Date: Thu, 20 Aug 2009 16:04:49 +0200 Subject: Support for the Calao TNY-A9260/TNY-A9G20 boards The Calao TNY-A9260 and TNY-9G20 are boards manufactured and sold by Calao Systems . Their components are very similar to the AT91SAM9260EK board, so their configuration is based on the configuration of this board. There are however some differences: different clocks, no LCD, no ethernet. They also can use SPI EEPROM to store the environment.
