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). Subversion repository: svn://194.85.238.22/home/users/george/svn/arm9eb

All suggested changes handled (If I forgot something please remind me). Rebased against u-boot-arm.git Hope to get review.
