From 2f3a71f235f442beb9419cee94ef6888b24f8259 Mon Sep 17 00:00:00 2001 From: "Ira W. Snyder" Date: Mon, 21 Nov 2011 13:20:33 -0800 Subject: mpc8xxx: update module_type values from JEDEC DDR3 SPD Specification Newer JEDEC DDR3 SPD Specifications define several additional values for the DDR3 module_type field which were undefined when this code was written. Update the code to handle the newer module types. Signed-off-by: Ira W.
