From 91671913f7db59dd876e86433d8f3462dbf66588 Mon Sep 17 00:00:00 2001 From: York Sun Date: Tue, 25 Jan 2011 22:05:49 -0800 Subject: powerpc/mpc85xx: implement workaround for errata DDR111 and DDR134 Workaround for the following errata: DDR111 - MCKE signal may not function correctly at assertion of HRESET DDR134 - The automatic CAS-to-Preamble feature of the DDR controller can calibrate to incorrect values These two workarounds must be implemented together because they touch common registers.
