From d4b3a86433d0c99f37dc4c94986c51e1d472712c Mon Sep 17 00:00:00 2001 From: Thomas Chou Date: Mon, 31 Dec 2007 18:16:04 +0800 Subject: [PATCH] nios2: fix memory module size detection The previous code does not work for bus width larger than 128 bits. This patch replace the limited test cases, and should work without bus width limitation.
