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

This patch was sumbitted while the merge window was open.
Is there any special reason it was not added, and the submitter received no feedback?
Best regards,

please update to the new network initialisation scheme.
Please rebase it also against the u-boot-arm/master
Note That just after the apply of your a common code will be create it will be nice it you can plan to retest it
