From ed9e4e427295623197d8dd76a1ca9ac15e085572 Mon Sep 17 00:00:00 2001 From: York Sun Date: Mon, 27 Oct 2014 11:31:32 -0700 Subject: [PATCH] mpc85xx/t208xqds: Adjust DDR timing parameters Adjust timing for dual-rank UDIMM, verified on M3CQ-8GHS3C0E for speed of 1066, 1333, 1600, 1866MT/s. The 1866 timing is copied to 2133 timing in case such DIMM comes available. Also update single-rank 1866 timing. Enable interactive debugging as well.
