From 3f9c542d3d69b1a10a5e193e779133a0454d1f44 Mon Sep 17 00:00:00 2001 From: Lee Nipper Date: Thu, 10 Apr 2008 09:35:06 -0500 Subject: mpc83xx: Update DIMM data bus width test to support 40-bit width 32-bit wide ECC memory modules report 40-bit width. Changed the DIMM data bus width test to 'less than 64' instead of 'equal 32'.
