Subject: [PATCH] ARM: mx53loco: Fix DD3 initialization
Date: Tue, 23 Aug 2011 21:11:04 -0300 [thread overview]
Message-ID: <1314144664-2752-1-git-send-email-festevam@gmail.com> (raw)
Updated mx53 ddr3 script in order to align with the latest Freescale version from July 8, 2011:
-change ESDREF[REF_SEL]=01 (for 32KHz), from incorrect setting of 00 (64KHz)
-change DDR3 MR0 write to "setmem /32 0x63fd901c = 0x052080b0" from "0x092080b0".
This changes write recovery from 8 clocks to 6 clocks(in line with ESDCFG1[tWR])
