From 49baa91d6863df480fa05eb57524a274f77fa886 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Thu, 8 Feb 2007 01:11:00 -0600 Subject: [POWERPC] 83xx: Updated and renamed MPC834x SYS to MPC834x MDS The MPC834x SYS board has always been called the MPC834x MDS since its public release. Removed all references to SYS and replaced with MDS. Additionally renamed the .dts to match the defconfig (mpc834x_mds*).
