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.
Signed-off-by: Albin Tonnerre albin.tonnerre@free-electrons.com --- Changes in v7: - As per Jean-Christophe's commentes, fix long lines and use uppercase for defines in include/configs/tny_a9260.h. Slightly rework the ifdef logic in the process - Add an entry in MAINTAINERS for the tny_a9g20 as weel, since both 9260 and 9g20 are supported
Changes in v8: - Update MAKEALL to reflect the changes in Makefile, and add the tny_a9g20
