From 1079432e04ccf71aa3684181186182cd63512f19 Mon Sep 17 00:00:00 2001 From: Sergey Lapin Date: Fri, 31 Oct 2008 12:28:43 +0100 Subject: Custom AFEB9260 board support 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).
