This patch provides support for AFEB9260 board, a product of
OpenSource hardware and software. Some commertial projects
are made with this design. A board is basically AT91SAM9260-EK
with some modifications and different peripherals and different
parts used. Main purpose of this project is to gain experience in
hardware design.
More info: http://groups.google.com/group/arm9fpga-evolution-board
(In Russian only, sorry).
