[PATCH 0/2] mvebu: ddr3: Armada-385 read ODT configuration

[Chris Packham <judge.packham@gmail.com>]

We've been doing some finer grained testing on our Armada-385 based
platforms and found that on a read the ODT was kicking in 3 clock cycles
too early.

It is likely this has gone unnoticed because prior to commit 247c80d6b8ad
("mv_ddr: ddr3: only use active chip-selects when tuning ODT") most
systems would have ended up maxing out the read ODT values.

Marvell have been directing us to add 3 to the min/max read calculation
and that seems to do the trick. Rather than just adding +3 I've adjusted
the existing manipulations.

I've only got access to our x530 platform at the moment so it would be
good if anyone with access to other Armada-385 could take this for a
spin.
