[U-Boot] [PATCH][Re-Submit2] Custom AFEB9260 board support
Sergey Lapin
slapin at ossfans.org
Mon Sep 29 21:52:40 CEST 2008
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

Fixed wrong leftovers of net/eth.c somehow appeared insde patch due to
rebase messed-up somewhere
