From c69d2e57616f20eb1989cfe235ee036a26c78d5a Mon Sep 17 00:00:00 2001 From: Thomas Chou Date: Thu, 28 Aug 2014 17:29:06 +0800 Subject: [PATCH] nios2: link to CONFIG_SYS_MONITOR_BASE and remove text_base hook This patch changes the link script to base at CONFIG_SYS_MONITOR_BASE. Then we can remove the text_base hook in nios2-generic board.
