From a1d558a20f1eaeae9927abc4e0978725d33bae53 Mon Sep 17 00:00:00 2001 From: York Sun Date: Mon, 8 Oct 2012 07:44:26 +0000 Subject: powerpc/mpc85xx: Add workaround for DDR erratum A004934 After DDR controller is enabled, it performs a calibration for the transmit data vs DQS paths. During this calibration, the DDR controller may make an inaccurate calculation, resulting in a non-optimal tap point.
