The Calao TNY-A9260 and TNY-9G20 are boards manufactured and sold by
Calao Systems <http://www.calao-systems.com>. 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.
