From 22d1a56cbfb0bff34f477b4db6a55d076d829b83 Mon Sep 17 00:00:00 2001 From: Jens Gehrlein Date: Wed, 26 Sep 2007 17:55:54 +0200 Subject: TQM885D: Exchanged SDRAM timing by a more relaxed timing. CAS-Latency=2, Write Recovery Time tWR=2 The max. supported bus frequency is 66 MHz. Therefore, changed threshold to switch from 1:1 mode to 2:1 from 80 MHz to 66 MHz.
