From 2e95c4d672ce6c931951c87b5dbfa4106fd3cae6 Mon Sep 17 00:00:00 2001 From: Zong Li Date: Wed, 17 Oct 2018 21:15:51 +0800 Subject: nds32: Remove the redundant assignment For early version, the value of r2 register was used to display a character on UART when error occurred. Remove these r2 assignments because we no longer show the character.
