Subject: [PATCH 2/2] Add support for MEMEC 2VP30-FF1152 eval board with simple FPGA design

From: Grant Likely <[email-masked]>
Date: Sat, 10 Sep 2005 01:37:39 -0600

Here is an example port to another V2PRO based board.

This patch is for information only and is NOT suitable for submission up to
mainline
